10. When the Traveler is resolving to SMPTE time code, the
LOCK light glows green when lockup has been achieved.
The TACH light blinks once per second when the Traveler
is successfully reading address (time code) information.
9. ADAT optical and TOSLink signal present LEDs.
8. 4-segment metering for AES/EBU input.
7. MIDI activity LEDs for MIDI input and output.
6. 4-segment metering for S/PDIF input.
5. These four 4-segment meters show input signal level for
the analog TRS input jacks on the rear panel.
4. These four 4-segment meters show input signal level for
the mic/instrument XLR/combo inputs on the rear panel.
The LCD shows each Traveler input (XLR/combo, TRS,
ADAT, SPDIF and AES/EBU), along with the current mix
parameter setting for each input. To change a setting,
scroll to it with the CURSOR knob and change it with the
VALUE knob.

1. These four detented digital trim knobs provide 53dB of
gain, but they also function as pad switches (when
pushed) for an additional 20dB of gain or reduction.
When you turn or push the knobs, you’ll see dynamic
feedback of your adjustment in the LCD display.The total
gain range — from when pad is enabled and the trim is
turned all the way down to when the pad disabled and
trim is turned all the way up — is 73dB. All four inputs
have preamps, so you can plug in just about anything: a
microphone, a guitar, a synth, or even a +4 signal. Use
the trim knob and input level meters 1-4 in the metering
section to calibrate the input signal level. The meters
cover both the TRS and XLR input.

14. These round LEDs indicate signal presence on the eight
rear-panel TRS analog outputs. Their threshold is around
-42 dB.They do not indicate clipping in any way; use your
host audio software level meters to calibrate output
levels. Outputs 1-2 serve as the main outs. Push and
then turn the front-panel volume knob for volume
control.
13. These four round “L/R” LEDs indicate signal presence on
the stereo S/PDIF and AES/EBU digital outputs.
19. These switches provide phantom power for their respective microphone input. Left is off; right is on. (Right on!)
18. This is a standard quarter-inch stereo headphone jack.
From the factory, its output matches the main outs on
the rear panel. But it can be programmed to mirror any
other output pair (digital or analog). It can even be
programmed to serve as its own independent output.
Use the volume knob above to control its level.
17. Use the SETUP and SELECT knobs to change system
settings like the Traveler sample rate and clock source.
The SETUP knob chooses the setting; the SELECT knob
modifies the current system setting displayed in the LCD.
Some settings require that you push SELECT instead of
turning it, or you may need to push it to confirm the
setting you’ve chosen by turning it.

12. These lights indicate the global sample rate at which the
Traveler is operating. Use the MOTU FireWire Audio
Console to set the sample rate or to choose an external
clock source, from which the sample rate will be derived.
When no clock signal is currently present, one of these
LEDs flashes rapidly. For example, if you’ve set the
Traveler to slave to an external clock, such as ADAT, but
there is no clock signal currently being detected, it
flashes.

4. These optical digital I/O connectors can be connected
either to an ADAT-compatible “lightpipe” device (such as
a digital mixer) or to a S/PDIF optical (“TOSLink”)
3. These are standard word clock jacks. Use them for a
variety of applications, such as for digital transfers with
devices that cannot slave to the clock supplied by their
digital I/O connection with the Traveler. When the
Traveler is operating at a 2x sample rate (88.2 or 96 kHz)
or 4x sample rate (176.4 or 192kHz), the word clock
output can either match the Traveler’s sample rate or be
reduced to the equivalent 1x rate (either 44.1 or 48 kHz).
This setting is made via the FireWire Audio Console. See
“Word Out” on page 44.
2. Connect the Traveler to the computer here using the
standard 1394 FireWire A cable provided with your
Traveler. Important note: it is best to turn off the
Traveler when plugging in the FireWire cable, as this
avoids the possibility of static discharge, which can
harm the electrical components in the Traveler or
your computer. Use the second FireWire port to daisychain up to four MOTU FireWire audio interfaces to a
single FireWire bus. You can also connect other FireWire
devices. For details, see “Connecting multiple MOTU
FireWire interfaces” on page 37.

6. These jacks provide stereo, 24-bit S/PDIF digital input
and output at any sample rate up to 96kHz. They are
disabled at the 4x rates (176.4 and 192kHz).
5. If you are using the Traveler with an ADAT, use this
standard ADAT SYNC INPUT to connect the Traveler to the
end of your ADAT sync chain. For example, if you have
three ADATs, chain the ADATs in the usual fashion (SYNC
OUT to SYNC IN, etc.), and then connect the last ADAT’s
SYNC OUT to this SYNC IN. This connection allows you to
make sample-accurate audio transfers between
AudioDesk (or other sample-accurate software) and the
ADATs. If you have a MOTU MIDI Timepiece AV or Digital
Timepiece, make it the master of the ADAT SYNC chain so
that you can control everything from AudioDesk (or your
other MIDI Machine Control compatible software).
compatible device, such as an effects processor or DAT
machine. Be sure to set the format in the MOTU FireWire
Audio Console software. (see “Optical input/output” on
page 43) for details.) ADAT optical supplies eight
channels of 24-bit digital I/O (4 channels at 96kHz).
TOSLink is stereo. Note: you can choose independent
formats for the optical IN and OUT. For example, you
could choose ADAT for the optical IN (for, say, eight
channels of input from your digital mixer) and S/PDIF for
the optical OUT (for, say, your DAT machine).

9. These 4 analog inputs are gold-plated, balanced TRS (tip/
ring/sleeve) quarter-inch connectors that can also
accept an unbalanced plug. The front panel LCD and
Cuemix Console software let you adjust them for either
+4dB or -10dB input signals. They have 24-bit, 64x
oversampling converters. These inputs (5 through 8) do
not have microphone preamps, so they are best used for
synthesizers, drum machines, effects processors, and
other instruments with line level signals.
8. These two balanced, quarter-inch jacks serve as the
Traveler’s main outputs. You can connect them to a set of
powered studio monitors and then control the volume
from the front panel volume knob. (Push the knob first to
switch to main out volume control.) To hear disk tracks in
your audio software on these main outs, assign the disk
tracks (and master fader) to these main outs
(Analog 1-2). You can also use CueMix DSP to monitor
live Traveler inputs here as well.
7. The Traveler’s eight analog outputs are gold-plated,

Traveler from a battery pack via the 4-in XLR jack), turn
this switch to the OFF position.
11. Connect a MIDI device here using standard MIDI cables.
Connect the Traveler’s MIDI OUT port to the MIDI IN port
on the other device. Conversely, connect the Traveler’s
MIDI IN port to the MIDI OUT port on the other device.
You can connect different devices to each port, such as a
controller device to the IN port and a sound module to
the OUT port. You can also daisy-chain MIDI devices, but
be sure to manage their MIDI channels (so that they
don’t receive or transmit on the same channel).

If you have a foot switch connected to
another MOTU FireWire interface, these
settings let you map the foot switch to any
computer keyboard key for both the up and
down position.This setting does not apply to
the Traveler, which does not have a foot
switch input.
Choosing a smaller setting here
reduces the delay you may hear
when listening to live input that
you are running through effects
plug-ins in your software. But
lower settings also increase the
strain on your computer. For
details, see “Samples Per Buffer”
on page 43.
Check this option if the audio software you
are using with the Traveler does not support
Windows WDM drivers and instead only
supports legacy MME (Wave) drivers. When
checked, this option makes all of the Traveler
inputs and outputs available to legacy Wavedriver compatible audio software.
This option should always be left
on (checked).There are only a few
rare cases in which you would
want to turn it off. For details,
refer to the MOTU tech support
database at www.motu.com.

If you are running a Traveler interface at a high sample rate
(88.2, 96, 176.4 or 192kHz), this
option appears in the interface
tab. It lets you choose a word
clock output rate that either
matches the global sample rate
(e.g. 192kHz) or reduces the word
clock output to the corresponding
1x rate (either 44.1 or 48kHz).

eight analog outputs and four quarter-inch inputs
are on balanced TRS +4dB quarter-inch jacks. All
of these jacks can also accept unbalanced plugs.
The quarter-inch analog inputs can be switched in
pairs between a +4 and -10dB reference level. An
additional 6dB of software boost can be applied to
each channel individually via the CueMix Console
software application or via the front panel LCD
display.
Optical
The Traveler optical jacks support two digital audio
formats: ADAT and S/PDIF. The ADAT optical
format provides eight channels of 24-bit digital
audio at either 44.1 or 48 kHz, and four channels at
88.2 or 96kHz. The optical S/PDIF format (often
referred to as TOSLink), supplies stereo S/PDIF
input or output. The optical jacks are disabled at
the 4x sample rates (176.4 and 192kHz).
AES/EBU
The Traveler rear panel provides a standard AES/
EBU digital input and output that supports digital
I/O at 44.1, 48, 88.2 and 96 kHz. The AES/EBU
jacks are disabled at the 4x sample rates (176.4 and
192kHz).
S/PDIF
The Traveler rear panel provides S/PDIF input and
output in two different formats: RCA “coax” and
optical “TOSLink”. The RCA jacks are dedicated to
the S/PDIF format. The TOSLink jacks can be used
either for either TOSLink or ADAT optical. The
optical input /output jacks can operate independently. For example, the optical input can be set to
10

TOSLink while the optical output is set to ADAT.
The RCA and optical S/PDIF jacks are disabled at
the 4x sample rates (176.4 and 192kHz).
On-board SMPTE synchronization
The Traveler can resolve directly to SMPTE time
code via any analog input, without a separate
synchronizer. The Traveler can also generate time
code via any analog output. The Traveler provides a
DSP-driven phase-lock engine with sophisticated
filtering that provides fast lockup times and subframe accuracy. Direct time code synchronization
is supported by Cubase, Nuendo and other audio
sequencer software that supports the ASIO2
sample-accurate sync protocol.
The included FireWire SMPTE Console™ software
provides a complete set of tools to generate SMPTE
for striping, regenerating or slaving other devices
to the computer.
ADAT sync: sample-accurate synchronization
The Traveler’s standard 9-pin ADAT SYNC IN
connector provides sample-accurate synchronization with all Alesis ADAT tape decks connected
to the system—or any device that supports the
ADAT sync format. For example, if you digitally
transfer a single track of material from an ADAT
via light pipe into audio workstation software on
the computer, and then transfer the track back to
the ADAT, it will be recorded exactly at its original
location, down to the sample.
Word clock
The Traveler provides standard word clock that can
slave to any supported sample rate. In addition,
word clock can resolve to and generate “high” and
“low” sample rates. For example, if the Traveler
global sample rate is set to 96 kHz, the word clock
input can resolve to a “low” rate of 48 kHz.
Similarly, when the Traveler is operating at 96 kHz,
the MOTU FireWire Audio Console lets you
choose a word clock output rate of 48 kHz.
1394 FireWire
The two 1394 FireWire jacks accept a standard
IEEE 1394 FireWire cable to connect the Traveler to
a FireWire-equipped Macintosh or Windows
computer. The second jack can be used to daisy
chain multiple interfaces — up to four MOTU
FireWire interfaces — on a single FireWire bus. It
can also be used to connect other FireWire devices
without the need for a FireWire hub. The Traveler
has the ability to power itself from its FireWire
connection to the computer.
THE TRAVELER FRONT PANEL
Phantom power
Individual 48V phantom power can be enabled for
each preamp with the four front panel switches.
Digital Precision Trim™ rotary encoders
The four Digital Precision Trim™ detented rotary
encoders provide preamp gain adjustment and also
serve as 20dB pad switches when pushed. When
you turn these trim knobs, input gain can be
adjusted in 1dB increments, and the LCD display
provides active numeric feedback as the
adjustment is made.
Headphone output and main volume control
The Traveler front panel includes a quarter-inch
stereo headphone output jack and volume knob.
The volume knob also controls the rear-panel main
outs. Push the knob to toggle between them. The
LCD display provides feedback.
CueMix™ DSP no-latency on-board mixing
The CueMix DSP section of the front-panel
provides access to the Traveler’s on-board mixing
features, as well as global system settings. Together,
these features provide complete stand-alone
operation, without a computer. The Traveler can
mix all inputs to any output pair, and up to four
such mixes can be independently programmed
and simultaneously operated.
11
ABOUT THE TRAVELER
!Traveler Manual/Win Page 12 Monday, November 29, 2004 3:50 PM
Backlit LCD display
Any Traveler setting can be accessed directly from
the front panel using the six rotary encoders and
the 2x16 backlit LCD display. CueMix DSP settings
such as input gain, panning, +4/-10 input level,
6dB boost, stereo pair grouping, mix output
assignment and others are quickly accessed, clearly
marked and easy to adjust. Sixteen presets can be
created, saved, recalled and duplicated.
Metering section
The front panel of the Traveler displays several
banks of input metering and output activity LEDs.
The round analog, SPDIF and AES/EBU output
activity LEDs, as well as the ADAT optical in/out
activity LEDs, display signal presence. The
threshold for these lights is approximately -42 dB.
The four-segment input meters provide dedicated
multi-segment metering for their respective inputs.
The Clock lights indicate the global sample rate (as
chosen in the MOTU FireWire Audio Console
software). The LOCK and TACH LEDs provide
feedback for the Traveler’s on-board SMPTE
synchronization features.
TRAVELER SIDE PANEL
MIDI I/O
The Traveler’s standard MIDI IN and MIDI OUT
jacks supply 16 channels of MIDI I/O to and from
the computer via the Traveler’s FireWire
connection.
Bus power
The Traveler can draw power from three possible
sources:
1. the computer (via the FireWire cable connection
between the Traveler and the computer)
2. an external battery pack (purchased separately)
If you are using FireWire bus power only, then the
Bus Power switch needs to be turned on. However,
if you are using battery or DC power, and you do
not wish to draw power from the computer (to
conserve your laptop battery, for example), you can
disable bus power by moving the Bus Power switch
to the Off position.
Battery power
The 4-pin XLR battery power jack allows you to
connect a standard DC battery pack for extended
remote recording. The battery pack must supply a
minimum of 10-18 volts and 12 watts. For further
details, contact your preferred supplier of
professional audio/video equipment.
Power supply
If you do not want the Traveler to draw power from
the computer, and AC power is available, you can
power the Traveler from any standard 10-18V,
12 watt DC power supply with any polarity (tip
positive or negative).
16-BIT AND 24-BIT RECORDING
The Traveler system handles all data with a 24-bit
signal path, regardless of the I/O format. You can
record and play back 16-bit or 24-bit audio files at
any supported sample rate via any of the Traveler’s
analog or digital inputs and outputs. 24-bit audio
files can be recorded with any compatible host
application that supports 24-bit recording.
HOST AUDIO SOFTWARE
The Traveler system ships with a standard WDM
Windows driver that allows you to record, edit,
play back and mix your Traveler projects using
your favorite Windows audio software.
The Traveler also includes ASIO2 and GSIF2
drivers for multi-channel compatibility with any
audio application that supports these drivers.
3. a DC power supply

ABOUT THE TRAVELER
!Traveler Manual/Win Page 13 Monday, November 29, 2004 3:50 PM
A COMPUTER-BASED SYSTEM
Regardless of what software you use with the
Traveler, the host computer determines the
number of tracks the software can record and play
simultaneously, as well as the amount of real-time
effects processing you can apply to your mix. A
faster computer with more RAM and faster hard
drives will allow more simultaneous tracks and
real-time effects than a slower computer with less
RAM and slower hard drives. Today’s fastest
computers can typically play as many as 72 tracks
or more.

■
1 pair of RCA S/PDIF in and out
■
1 pair of AES/EBU in and out
■ 1 pair of optical in/out switchable between
ADAT (“Lightpipe”) or optical S/PDIF (TOSLink)
Here are a few things you should keep in mind as
you are making these connections to other devices.
Figure 4-1: Connecting the Traveler to the computer.
Mic/guitar/instrument inputs
Connect a microphone, guitar or other similar
instrument to the front-panel inputs, as
recommended in the table below. If your
microphone requires phantom power, move the
48V phantom power switch on the front panel to
the right (enabled). Use the trim knobs on the front
panel to adjust the input level as needed for each
input. The LCD provides feedback for the current
trim setting. The Traveler’s input trims are digital
controlled, so they allow you to make fine-tuned
adjustments in approximately 1dB increments. Use
the four input level meters on the front panel
(labeled ANALOG 1-4) to calibrate the level. These
meters register for both the XLR and TRS input.

To toggle the pad, push the input’s trim knob. The
LCD provides feedback for the current pad setting.
The pad settings above are recommended initial
settings. Use the front-panel trim knobs to adjust
input levels, and use the Traveler’s front-panel
4-segment meters to adjust the gain accordingly. If
necessary, after adjusting the trim, you can enable
or disable the pad as needed, depending on actual
signal levels.
Quarter-inch analog
The quarter-inch analog inputs (5-8) and outputs
(1-8) are balanced TRS connectors that can also
accept an unbalanced plug. The outputs are all
referenced to +4dBu. The inputs can be manually
set to either +4 or -10dBu. Use the front panel
controls to adjust the reference level (+4/-10) as
needed for each input (or input pair) as follows:
S/PDIF “TOSLink” device. Just make the
connections as needed and then you’ll set the
format later in the MOTU FireWire Audio Console.
Input and output are independent. For example,
you could connect ADAT optical input from your
digital mixer and connect TOSLink optical output
to your DAT deck.
The optical S/PDIF jacks are disabled at the 4x
sample rates (176.4 and 192kHz).
Analog outputs 1-2 can serve as main outs
Analog outputs 1-2 can serve as main outputs. The
main out volume is controlled by the volume knob
on the front panel. Push the knob to toggle
between phone and main out volume control. In a
standard studio configuration, the main outs are
intended for a pair of studio monitors, but they can
also be used as regular outputs for any purpose.
1 Turn the PARAM knob until you see the “4/10”
setting displayed in the LCD, as shown below.
CONNECT MIDI GEAR
If turning the PARAM knob doesn’t do anything,
press the SETUP knob once, and then turn it.
Connect your MIDI device’s MIDI IN jack to the
Traveler’s MIDI OUT jack (Connection A below).
Conversely, connect the MIDI device’s MIDI OUT
jack to the Traveler’s MIDI IN jack (Connection B).

shown in Figure 4-3. Similarly, devices that never
send data, such as a sound module, only need
Connection A. Make both connections for any
device that needs to both send and receive MIDI
data.
Connecting additional gear with MIDI THRUs
If you need to connect several pieces of MIDI gear,
run a MIDI cable from the MIDI THRU of a device
already connected to the Traveler to the MIDI IN
on the additional device as shown below in
Figure 4-4. The two devices then share the
Traveler’s MIDI OUT port. This means that they
share the same set of 16 MIDI channels, too, so try
to do this with devices that receive on only one
MIDI channel (such as effects modules) so their
receive channels don’t conflict with one another.

POWER OPTIONS
The Traveler can draw power from three possible
sources:
1. the computer (via FireWire)
2. an external battery pack
3. a DC power supply
Figure 4-5: The Traveler’s battery and power supply options.
Bus power requirements
The Traveler draws all the power it needs from the
FireWire bus connection to the computer.
However, the FireWire connection to the computer
must meet all of the requirements discussed below.
6-pin FireWire connectors
The Traveler can only draw power over the
FireWire bus from a 6-pin to 6-pin cable, or a 6-pin
to 9-pin (FireWire B) cable. It cannot draw power
from a FireWire cable with a 4-pin connector, as
shown below:

22
INSTALLING THE TRAVELER HARDWARE
!Traveler Manual/Win Page 23 Monday, November 29, 2004 3:50 PM
When operating under bus power, daisy-chaining
is not recommended
The Traveler can be daisy-chained with other
FireWire devices from a single FireWire
connection to the computer. However, if the
Traveler is operating under bus power, this is not
recommended. If you need to daisy chain the
Traveler with other devices on the same FireWire
bus, power the Traveler with a DC power supply
(or battery), and turn off the Bus Power switch on
the side panel. The other devices on the chain
should also have their own power supply. In
general, bus-powered FireWire devices should not
be daisy-chained.
FireWire adapter products must be powered
If you are using a FireWire adapter (a third-party
product that supplies one or more FireWire ports
to your computer), it must have direct access to a
power supply:
PCI FireWire cards — If you plan to connect the
Traveler to a PCI card and run the Traveler under
bus power, the PCI card must have a direct
connection to the power supply harness inside
your computer. This is the same power supply
harness to which you connect internal hard drives,
CD/DVD drives, etc.
■
PCMCIA slot adapters — If you plan to connect
the Traveler to a PC card FireWire adapter
(inserted in the PC card slot in your laptop), it
must provide a 6-pin connection and it must also
have its own power supply. Most commonly, these
types of products have a DC power adapter that
plugs into an AC wall outlet. As you can see,
however, this situation does not allow for remote
battery operation, as the PC card adapter requires
AC.
■
Examples of bus- powered operation
Here are a few typical examples of bus-powered
Traveler operation:
Bus power from a desktop computer
Your desktop computer is running off of its usual
AC power connection, and the Traveler draws
power from the FireWire cable connected to the
computer. There are no limits to running time.
Bus power from an AC-powered laptop
This scenario is identical to the desktop situation
described above: the laptop is powered by AC, the
Traveler is powered via the FireWire bus and there
are no limits to running time.
Bus power from a battery-powered laptop
The laptop is being powered by its own battery, and
the Traveler is being powered by its FireWire
connection to the computer. So the laptop battery
is supplying power to both the laptop and the
Traveler. This is the most compact and portable
operating scenario. Running time is determined by
the capacity of the laptop battery. For extended
recording sessions, bring extra, fully charged
laptop batteries.
Powering the Traveler from a battery pack
The 4-pin XLR battery jack on the Traveler side
panel allows you to connect a standard DC battery
pack, which is ideal for extended remote recording.
These products can provide multiple hours of
operation, depending on their capacity. The
battery pack should supply 10-18 volts and 12
watts. A typical application would employ a 12 volt
battery, therefore requiring 1 amp. In this scenario,
a 1 amp-hour battery will power the unit for
1 hour. A 10 amp-hour battery will power the unit
for 10 hours. Follow the manufacturer’s recommendations for battery discharge for proper
battery maintenance. For further details, contact
your preferred supplier of professional audio/video
equipment.

If you do not want the Traveler to draw power from
the computer, and AC power is available, you can
power the Traveler from any standard 8-18 volt,
12 watt DC power supply with any polarity (tip
positive or negative), and amperage as shown
below. To prevent the Traveler from drawing power
from the computer, turn off the Bus Power switch.

not the Traveler draws power from the computer
via FireWire.
For example, when battery or DC power supply
options are not being used, and FireWire is the
only available power source, turn on the Bus Power
switch.
If you are powering the Traveler via battery or DC
power supply, and you do not want it to draw
power from the computer (perhaps because it is a
laptop running under its own battery, and you
don’t want the Traveler to run down the laptop’s
battery unnecessarily), turn off the Bus Power

USING THE TRAVELER WITH A MIXER
While there are many ways to use the Traveler with
an external mixer, typically the Traveler serves as a
multi-channel “pipeline” between the mixer and
the computer. If your mixer is analog, connect the
analog section of the Traveler to your mixer. If your
mixer is digital, and it has ADAT optical I/O, you
can connect them optically as shown below in
Figure 4-8. The Traveler’s available analog, SPDIF
and AES/EBU inputs and outputs can serve as an
extension to the mixer I/O, but then you will
probably find yourself mixing in two places: the
mixer and the computer. A word of advice: if you
would like to use the Traveler with an external
mixer, use the mixer for mixing. Trying to mix
large multitrack projects in two places can become
very cumbersome very quickly.

MAKING SYNC CONNECTIONS
If you connect devices digitally to the Traveler, or if
you need to synchronize the Traveler with an
outside time reference such as SMPTE time code,
you must pay careful attention to the synchronization connections and clock source issues
discussed in the next few sections.
Do you need to synchronize the Traveler?
If you will be using only the Traveler’s analog inputs
and outputs (and none of its digital I/O), and you
have no plans to synchronize your Traveler system
to SMPTE time code, you don’t need to make any
sync connections. You can skip this section and
proceed to “MOTU FireWire Audio Console” on
page 39 where you’ll open the MOTU FireWire
Audio Console and set the Clock Source setting to
Internal as shown below. For details, see “Clock
Source” on page 40.
Synchronization is critical for clean digital I/O
Synchronization is critical in any audio system, but
it is especially important when you are transferring
audio between digital audio devices. Your success
in using the Traveler’s digital I/O features depends
almost entirely on proper synchronization. The
following sections guide you through several
recommended scenarios.
Be sure to choose a digital audio clock master
When you transfer digital audio between two
devices, their audio clocks must be in phase with
one another — or phase-locked. Otherwise, you’ll
hear clicks, pops, and distortion in the audio — or
perhaps no audio at all.
Not phase-locked
Phase-locked
Device A
Device B
Figure 4-10: When transferring audio, two devices must have phaselocked audio clocks to prevent clicks, pops or other artifacts.
There are two ways to achieve phase lock: slave one
device to the other, or slave both devices to a third
master clock. If you have three or more digital
audio devices, you need to slave them all to a single
master audio clock.
Figure 4-9: You can run the Traveler under its own internal clock when
it has no digital audio connections and you are not synchronizing the
Traveler system to an external time reference such as SMPTE.

Situations that require synchronization
There are three general cases in which you will
need to resolve the Traveler with other devices:
Slave
Synchronizing the Traveler with other digital
audio devices so that their digital audio clocks are
phase-locked (as shown in Figure 4-10)
Slave

■
Slaving the Traveler system to SMPTE time code
from a video deck, analog multi-track, etc.
■
■
Both of the above
Figure 4-11: To keep the Traveler phased-locked with other digital
audio devices connected to it, choose a clock master.
Also remember that audio phase lock can be
achieved independently of time code (location).
For example, one device can be the time code
master while another is the audio clock master. But
only one device can be the audio clock master. If
you set things up with this rule in mind, you’ll have
trouble-free audio transfers with the Traveler.

DO YOU NEED A SYNCHRONIZER?
Whether or not you’ll need a synchronizer depends
on your gear and what you will be doing with your
Traveler system. The following pages give you
specific information about common sync
scenarios. At least one of them will likely apply to
you. Here are some general considerations to help
you figure out if you need (or want) a synchronizer
for your Traveler system.
You don’t need a synchronizer if...
As explained earlier, the Traveler’s digital audio
clock must be phase-locked (synchronized) with
other connected digital audio devices to achieve
clean digital transfers between them. Can this be
accomplished without an additional digital audio
synchronizer? It depends on the nature of the other
devices, and what you want to do with them. You
don’t need a synchronizer if the device has a way of
locking itself directly to the Traveler’s clock (via
ADAT lightpipe, S/PDIF, AES/EBU or word clock),
AND if the device carries no sense of location in
time. A digital mixer is a good example: it can slave
to its ADAT lightpipe connection from the Traveler,
and it has no sense of time; it just passes audio
through for mixing.
A stand-alone digital recorder, on the other hand,
does have a sense of location in time, either via
SMPTE time code or via its own sample address.
For example, if you want to fly tracks back and
forth between your computer and an Alesis hard
disk recorder while maintaining the audio’s
position in time, the ADAT Sync port on the
Traveler lets you do so without a separate
synchronizer — and with sample-accurate
precision, as long as you’re using sample-accurate
software. Just connect the Traveler directly to the
Alesis recorder (or other ADAT Sync-compatible
device) as discussed in “Sample-accurate ADAT
sync with no synchronizer” on page 31. But if you
also want transport control over the entire rig
(including the hard disk recorder) from your audio
software, you’ll need a MIDI Machine Controlcompatible synchronizer such as MOTU’s MIDI
Timepiece AV, as discussed in “Sample-accurate
sync” on page 29. If you are simply using a standalone recorder as a way to capture live tracks that
you then transfer in one pass into the computer, no
synchronizer is required because the tracks will
remain in perfect phase lock with each other as you
transfer them together. You can simply slave the
stand-alone recorder to the optical output from the
Traveler as explained in “Syncing optical devices”
on page 34.
Transport control from your computer
If you have stand-alone digital recorders connected
to the Traveler, and they support ADAT Sync, your
audio software — if it supports MIDI Machine
Control (MMC) — allows you to control the
transports of everything from your computer.
Most advanced audio programs support MMC. To
do this, you’ll also need an MMC-compatible
ADAT synchronizer such as a MOTU MIDI
Timepiece AV. Synchronizers like these allow you
to play, stop, rewind and locate all of your tape
decks using the transport controls in the audio
software. If your audio software supports sampleaccurate sync, you can do so with sample-accurate
precision. The following pages show you how to
achieve MMC control, where possible.
Continuous sync to SMPTE / MTC
The Traveler can synchronize directly to SMPTE
time code. If your audio software supports sampleaccurate sync, it can also resolve to time code via
the Traveler. If your software does not support
sample-accurate sync, you need a dedicated
synchronizer, as illustrated on the following pages.

SAMPLE-ACCURATE SYNC
Your Traveler system provides you with the most
advanced, accurate synchronization possible with
Alesis modular digital tape decks and hard disk
recorders — or any device that supports sampleaccurate ADAT sync. Figure 4-12 below shows a
few best-case scenarios. Below is a brief
explanation of the benefits you achieve with these
setups.
Transport control from your computer
If you have a MIDI Timepiece AV, Digital
Timepiece or any ADAT synchronizer that also
supports MIDI Machine Control (MMC), you can
play, stop, rewind and locate all of your ADATs
using the transport controls in the audio software
running on your computer. This includes cueing
features like markers, position bars, playback
wipers, time rulers, etc.
Sample accurate locating
With sample accurate locating, when you transfer
audio between any other sample-accurate host
software and a sample-accurate recorder, the audio
will not drift in time — even by as little as one
sample. This is the tightest possible synchronization between digital audio devices. The timing in
your audio will not be affected in any way by the
process of transferring it between the Traveler and
the recorder.
Is your audio software sample-accurate?
Sample-accurate locating is only possible with
software that supports this feature through the
Traveler’s ASIO Version 2 driver.
Figure 4-13: Cubase SX and other ASIO 2.0-compatible programs
support sample-accurate transfers with ADAT Sync compatible
digital tape decks and modular hard disk recorders.

Use this setup if you have:
The Traveler system can resolve directly to SMPTE
time code. It can also generate time code and word
clock, under its own clock or while slaving to time
code. Therefore, the Traveler can act both as an
audio interface and digital audio synchronizer, to
which you can slave other digital audio devices.
You can use the Traveler to slave your audio
software to SMPTE as well, as long as your software
supports sample-accurate sync, which is the means
by which the software follows the Traveler. The
accuracy may not be sample-accurate, but in most
cases it will be very close.

SYNCING TO VIDEO AND/OR SMPTE TIME
CODE USING A SYNCHRONIZER
If your host audio software does not support the
Traveler’s on-board SMPTE sync features (because
your software does not support sample-accurate
sync), you need a universal synchronizer, such as a
MOTU MIDI Timepiece AV. These dedicated sync
boxes can read video and SMPTE time code and
then convert it into word clock and MIDI Time
Code (MTC). The word clock goes to the Traveler
to resolve the audio hardware, and MIDI Time
Code is fed to your host audio software, which
locks to it, as shown below in Figure 4-16.
Use this setup if you have:
✓ Video and/or a SMPTE time code source.
✓ A Digital Timepiece, MIDI Timepiece AV or other universal

SYNCING OPTICAL DEVICES
For ADATs or other devices that support ADAT
sync, synchronize them with the Traveler as
described in the previous sections of this chapter.
The word optical is our short-hand way of referring
to any device that connects to the Traveler via an
optical cable. But we make a further distinction: an
optical device is also one that doesn’t care about
sample location. An example is a digital mixer.
Since a digital mixer is not a recording device, it has
no sense of sample location like an ADAT does. An
ADAT can cue to a specific sample number (e.g.
sample number 43,478, 103) — as can any device
that supports ADAT sync, but most digital mixers
simply mix and process audio digitally, with no
sense of a specific sample location. There are many
other devices that fall into this category, including
digital effects processors, synthesizers, A/D
converters, and many more.
For optical devices, such as digital mixers, all you
have to do is make sure that their digital audio
clock is phase-locked (in sync with) the Traveler.
There are three ways to do this:
■
Slave the optical device to the Traveler
■
Slave the Traveler to the optical device
■ Slave both the optical device and the Traveler to
a third master clock (such as a Digital Timepiece or
MIDI Timepiece AV synchronizer)

SYNCING S/PDIF AND AES/EBU DEVICES
DAT decks and other devices with S/PDIF and/or
AES/EBU digital I/O will sync to the Traveler in
one of two ways:
■
Via the S/PDIF or AES/EBU connection itself
■
Via word clock
Devices with no word clock
If your S/PDIF or AES/EBU device has no word
clock sync connectors, just connect it to the
Traveler via the S/PDIF or AES/EBU connectors.
When the device records a digital audio signal
(from the Traveler), it will simply synchronize to
the clock provided by the digital audio input.
Traveler
S/PDIF or AES/EBU
On the other hand, when you transfer audio from
the S/PDIF or AES/EBU device into the Traveler,
you’ll have to slave the Traveler to its S/PDIF or
AES/EBU input. If you have other digital audio
devices connected to the Traveler, and they are not
slaved directly to the Traveler itself, you may hear
clicks and pops resulting from their unsynchronized audio clock. If so, just turn them off during
the transfer.
Devices with word clock
If your S/PDIF or AES/EBU device has a Word
Clock input, slave the device to the Traveler via
their word clock connection. You can then freely
transfer audio between the Traveler and the S/PDIF
device.

itself. In this case, you have to choose S/PDIF or AES/EBU as the Traveler’s clock source when recording from the other device. If you don’t want to
have to worry about switching the Clock Source setting depending on the direction of the digital transfer, you can slave the other device to word
clock from the Traveler or vice versa (not shown). The Word Clock connection maintains sync, regardless of the direction of the transfer.

SYNCING WORD CLOCK DEVICES
The Traveler word clock connectors allow you to
synchronize it with a wide variety of other word
clock-equipped devices.
For standard word clock sync, you need to choose
an audio clock master (as explained in “Be sure to
choose a digital audio clock master” on page 27).
In the simplest case, you have two devices and one
is the word clock master and the other is the slave

Don’t chain word clock
If you have three or more digital audio devices that
you need to synchronize, avoid chaining their word
clock connections (OUT to IN, OUT to IN, etc.), as
this causes problems. Instead, use a dedicated
synchronizer like the Digital Timepiece or a word
clock distribution device of some kind.
Slaving to 2x and 1/2x word clock
All MOTU FireWire audio interfaces that support
96 and 192 kHz operation (including the 896HD)
have the ability to slave to a word clock signal
running at the 1x sample rate that corresponds to
their current clock rate. For example, the Traveler
could be running at 192 kHz while slaving to a
48 kHz word clock signal from a MOTU MIDI
Timepiece AV. Similarly, the Traveler could run at
88.2 kHz and slave to 44.1 kHz word clock. In all of
these cases, the front panel clock LEDs flash both
sample rates to indicate that the Traveler is slaving
to word clock at the corresponding 1x clock rate.
But if the Traveler is running at 96 kHz, it cannot
slave to word clock running at 44.1 kHz.

Synchronizing multiple interfaces
All connected MOTU FireWire interfaces get their
clock from whatever you choose from the Clock
Source menu in the General tab in the MOTU
FireWire Audio Console. When you connect
multiple MOTU FireWire interfaces, all of their
respective sync sources are displayed in the menu
as shown below in Figure 4-23.
or 896HD’s, which have two FireWire ports
convenient for daisy-chaining. Up to four
interfaces can be combined on one FireWire bus.
Operating multiple FireWire interfaces at high
sample rates
Four MOTU FireWire interfaces can operate at
44.1 or 48kHz on a single FireWire bus. At the 2x
samples rates (88.2 or 96kHz) and 4x sample rates
(176.4 and 192kHz), you can operate no more than
three FireWire interfaces on a single FireWire bus.
Adding additional interfaces with a second
FireWire bus
Third-party FireWire bus expansion products in
the form of a cardbus (“PC card”) adaptor or PCI
card allow you to add a second FireWire bus to
your computer. In may be possible to add
additional MOTU FireWire interfaces connected
to such a third-party product, depending on the
performance of the product and the performance
of your host computer.
Figure 4-23: All MOTU FireWire audio interfaces get their clock from a
single master sync source on any connected Traveler (or other MOTU
FireWire interface). After you choose a source from this menu, the
entire system, including all connected Travelers, synchronizes to it.
Each FireWire interface in the system gets its clock
from the computer (unless it is the master clock
itself). There is no need to make word clock
connections between multiple FireWire interfaces.
Connecting other MOTU FireWire interfaces
You can add an original MOTU 828 to the end of a
FireWire daisy chain (because the 828 has only one
FireWire port), or you can mix and match multiple
828’s with other MOTU FireWire interfaces using a
standard FireWire hub. You can also add 828mkII’s
Managing the IDs of multiple interfaces
Multiple Traveler interfaces are identified by
number (#1, #2, #3, etc.) Interfaces are ID’d (given
a number) by the order in which they are first
powered up after being connected. This
information is stored in the MOTU FireWire Audio
preferences file. Once ID’d, they retain the same
number regardless of the order in which they are
powered up. You can disable an interface at any
time with the Disable interface option shown in
Figure 4-22 on page 37. Doing so frees up the
FireWire bandwidth required by the interface
without turning it off. Switching off an interface
accomplishes the same thing. To get the MOTU
FireWire Audio Control Panel Console to forget
about an interface entirely, you’ll see a Forget
button in the MOTU FireWire Audio Console. Just
click the Forget button and the MOTU FireWire
Audio Console will no longer consider the
interface to be present but off line (turned off).

ACCESSING THE TRAVELER SETTINGS
There are several ways to access the MOTU
FireWire Audio Console settings:
■ From the front panel LCD (see chapter 6,
“Traveler Front Panel Operation” (page 45)).
Traveler tab settings
The Traveler tab provides settings that apply to a
specific Traveler interface. If you have several
Travelers (or other MOTU FireWire audio
interfaces) connected, you’ll see a separate tab for
each one.
General tab settings
The General tab provides settings that apply
globally to all connected MOTU FireWire
interfaces.
■ From the Windows Start menu, choose
Programs>MOTU>MOTU FireWire Audio Console
■ In Cubase SX, open the Device Setup window,
click VST Audiobay and choose MOTU FireWire
Audio from the Master ASIO Driver menu. Then
click the MOTU FireWire Audio item in the list and
click the Control Panel button as shown below.
■ From within other ASIO-compatible programs,
refer to their documentation.

!Traveler Manual/Win Page 40 Monday, November 29, 2004 3:50 PM
TRAVELER SETTINGS
Sample Rate
Choose the desired Sample Rate for recording and
playback. The Traveler can operate at 44.1 (the
standard rate for compact disc audio), 48, 88.2, 96,
176.4 or 192kHz. Make absolutely sure that all of
the devices connected digitally to the Traveler
match the Traveler’s sample rate. Also make sure
that your Digital Timepiece, MIDI Timepiece AV
or other digital audio synchronizer matches it as
well. At the 4x sample rates (176.4 or 192kHz), all
digital I/O on the Traveler is disabled.
☛
Mismatched sample rates cause distortion and
crackling. If you hear this sort of thing, check the
sample rate settings in your hardware and here in
the MOTU FireWire Audio Console.
Operation at 4x sample rates (176.4 or 192kHz)
At the 4x sample rates (176.4 or 192kHz),
operation of the Traveler is restricted, due to the
higher audio bandwidth demands, as follows:
■ All digital I/O is disabled (there is no optical,
TOSLink, S/PDIF or AES/EBU input/output).
■ The Traveler provides 8 channels of analog input
and 8 channels of analog output, simultaneously.
■ The Mix1 input, as described in “Mix1 1-2” on
page 65, is not available.
■ The headphone output can be assigned to any
analog output pair or the Phones setting (as
described in “Phones” on page 44). But at the 4x
sample rates, the Phones output is not available
from the computer. Instead, it is only available as a
destination for the four CueMix DSP mixes. In
other words, it can only take CueMix inputs.
■
The main outs mirror the phones.
Clock Source
The Clock Source determines the digital audio
clock that the Traveler will use as its time base. For
a complete explanation of synchronization issues,
Figure 5-1: The MOTU FireWire Audio Console gives you access to all of the settings in the Traveler hardware.
40
MOTU FIREWIRE AUDIO CONSOLE
!Traveler Manual/Win Page 41 Monday, November 29, 2004 3:50 PM
see “Making sync connections” on page 27. The
following sections briefly discuss each clock source
setting.
Internal
Use the Internal setting when you want the Traveler
to operate under its own digital audio clock. For
example, you may be in a situation where all you
are doing is playing tracks off hard disk in your
digital audio software on the computer. In a
situation like this, you most often don’t need to
reference an external clock of any kind.
Another example is transferring a mix to DAT. You
can operate the Traveler system on its internal
clock, and then slave the DAT deck to the Traveler
via the S/PDIF connection (usually DAT decks
slave to their S/DIF input when you choose the
S/PDIF input as their record source) or via the
Traveler’s word clock output (if your DAT deck has
a word clock input).
If you would like help determining if this is the
proper clock setting for your situation, see “Do you
need a synchronizer?” on page 28.
With ADAT devices, however, you usually want an
external digital audio synchronizer, such as the
MIDI Timepiece AV or Digital Timepiece, to be the
digital clock master. In this case, you would set the
Traveler clock source setting to ADAT 9-pin, as
described below.
AES/EBU
The AES/EBU clock source setting refers to the
AES/EBU XLR input jack on the Traveler. This
setting allows the Traveler to slave to another
AES/EBU device.
Use this setting whenever you are recording input
from a DAT deck or other AES/EBU device into the
Traveler. It is not necessary in the opposite
direction (when you are transferring from the
Traveler to the DAT machine).
For further details about this setting, see “Syncing
S/PDIF and AES/EBU devices” on page 35.
S/PDIF
The S/PDIF clock source setting refers to the
S/PDIF RCA input jack on the Traveler. This
setting allows the Traveler to slave to another
S/PDIF device.
Use this setting whenever you are recording input
from a DAT deck or other S/PDIF device into the
Traveler. It is not necessary in the opposite
direction (when you are transferring from the
Traveler to the DAT machine).
For further details about this setting, see “Syncing
S/PDIF and AES/EBU devices” on page 35.
Word Clock In
The Word Clock In setting refers to the Word Clock
In BNC connector on the Traveler rear panel.
Choosing this setting allows the Traveler to slave to
an external word clock source, such as the word
clock output from a digital mixer.
ADAT 9-pin
The ADAT 9-pin clock source setting refers to the
ADAT digital audio synchronization format. It
allows the Traveler to slave to an ADAT — or ADAT
sync chain — via its ADAT sync 9-pin connector.
ADAT sync also carries precise, sample location
information, which allows Cubase or other sampleaccurate ASIO 2.0-compatible audio software to
transfer audio to and from ADAT-sync compatible
recorders without drifting by as much as one
sample.
Use this setting when you are using the Traveler
with one or more ADAT-sync compatible
recorders. Make sure the Traveler is connected to
the end of the ADAT sync chain.
41
MOTU FIREWIRE AUDIO CONSOLE
!Traveler Manual/Win Page 42 Monday, November 29, 2004 3:50 PM
You should also use this setting if you have a MIDI
Timepiece AV, which allows you to drive your
entire system from the transport controls of your
audio software.
You could also use ADAT sync to continuously
resolve the Traveler to SMPTE time code, video,
and word clock via a synchronizer like the MOTU
MIDI Timepiece AV. Word clock can accomplish
the same thing.
For further details, see “Sample-accurate ADAT
sync” on page 30, “Sample-accurate ADAT sync
with no synchronizer” on page 31 and “Syncing to
video and/or SMPTE time code using a
synchronizer” on page 33.
ADAT optical
The ADAT optical clock source setting refers to the
clock provided by the Traveler’s optical input,
when it is connected to an ADAT optical device.
This setting can be used to slave the Traveler
directly to the optical input connection. Most of
the time, you can set up a better operating scenario
that uses one of the other synchronization options.
However, there may be occasions when you have an
ADAT optical compatible device that has no way of
synchronizing digitally to the Traveler or an
external synchronizer such as the Digital
Timepiece. In this case, the ADAT Optical clock
source setting lets you slave the Traveler to the
device itself via its digital input to the Traveler.
If the ADAT Optical setting does not appear in the
menu, it means that the Traveler’s optical input is
currently either turned off or set to the TOSLink
format. In either case, choose the ADAT optical
format from the Optical input menu (Figure 5-1 on
page 40).
reference and shared transport control are not
needed — without having to set up an elaborate
synchronization scenario.
For further details about this setting, see “Syncing
optical devices” on page 34.
TOSLink
The TOSLink clock source setting refers to the
clock provided an optical S/PDIF device connected
to the Traveler’s optical input. This setting can be
used to slave the Traveler directly to the optical
input connection. Most of the time, you can set up
a better operating scenario that uses one of the
other synchronization options. However, there
may be occasions when you have an TOSLinkcompatible device that has no way of
synchronizing digitally to the Traveler or an
external synchronizer such as the Digital
Timepiece. In this case, the TOSLink clock source
setting lets you slave the Traveler to the other
device via the Traveler’s optical input.
If the TOSLink setting does not appear in the
menu, it means that the Traveler’s optical input is
currently either turned off or set to the ADAT
optical format. In either case, choose the TOSLink
format from the Optical input menu (Figure 5-1 on
page 40).
This setting is also useful if you just need to make a
simple, click-free digital transfer between the
Traveler and another device — where a time code
reference and shared transport control are not
needed — without having to set up an elaborate
synchronization scenario.
For further details about this setting, see “Syncing
optical devices” on page 34.
This setting is also useful if you just need to make a
simple, click-free digital transfer between the
Traveler and another device — where a time code
42
MOTU FIREWIRE AUDIO CONSOLE
!Traveler Manual/Win Page 43 Monday, November 29, 2004 3:50 PM
SMPTE
Choose this setting to resolve the Traveler directly
to SMPTE time code (LTC) being received via any
analog input on the Traveler. For details, see
“Syncing to SMPTE time code” on page 32 and
chapter 11, “FireWire SMPTE Console” (page 79).
Samples Per Buffer
The Samples Per Buffer setting lets you reduce the
delay you hear when patching live audio through
your audio software. For example, you might have
a live microphone input that you would like to run
through a reverb plug-in that you are running in
your host audio software. When doing so, you may
hear or feel some “sponginess” (delay) between the
source and the processed signal. If so, don’t worry.
This effect only affects what you hear: it is not
present in what is actually recorded.
You can use Samples Per Buffer setting to reduce
this monitoring delay—and even make it
completely inaudible.
☛
If you don’t need to process an incoming live
signal with software plug-ins, you can monitor the
signal with no delay at all using CueMix Console,
which routes the signal directly to your speakers
via hardware. For details, see chapter 10, “CueMix
Console” (page 71).
Adjusting the Samples Per Buffer setting impacts
the following things:
■
The strain on your computer’s CPU
■ The delay you hear when routing a live signal
through your host audio software plug-ins
■ How responsive the transport controls are in
your software
This setting presents you with a trade-off between
the processing power of your computer and the
delay of live audio as it is being processed by
plug-ins. If you reduce the Samples Per Buffer, you
reduce patch thru latency, but significantly increase
the overall processing load on your computer,
leaving less CPU bandwidth for things like realtime effects processing. On the other hand, if you
increase the Samples Per Buffer, you reduce the load
on your computer, freeing up bandwidth for
effects, mixing and other real-time operations. But
don’t set the Samples Per Buffer too low, or it may
cause distortion in your audio.
If you don’t process live inputs with software
plug-ins, leave this setting at its default value of
1024 samples. If you do, try settings of 256 samples
or less, if your computer seems to be able to handle
them. If your host audio software has a processor
meter, check it. If it starts getting maxed out, or if
the computer seems sluggish, raise the Samples Per
Buffer until performance returns to normal.
If you are at a point in your recording project where
you are not currently working with live, patchedthru material (e.g. you’re not recording vocals), or
if you have a way of externally monitoring input,
choose a higher Samples Per Buffer setting.
Depending on your computer’s CPU speed, you
might find that settings in the middle work best.
The Samples Per Buffer setting also impacts how
quickly your audio software will respond when you
begin playback, although not by amounts that are
very noticeable. Lowering the Samples Per Buffer
will make your software respond faster; raising the
Samples Per Buffer will make it a little bit slower, but
barely enough to notice.
Monitoring live inputs without plug-in effects
As mentioned earlier, CueMix Console allows you
to monitor dry, unprocessed live inputs with no
delay at all. For complete details, see chapter 9,
“Reducing Monitoring Latency” (page 65).
Optical input/output
The Optical input and Optical output settings let
you choose between ADAT optical (‘lightpipe’) and
S/PDIF optical (‘TOSLink’) as the format for the
43
MOTU FIREWIRE AUDIO CONSOLE
!Traveler Manual/Win Page 44 Monday, November 29, 2004 3:50 PM
Traveler’s optical input and output. Choose the
format that matches the device connected. If you
are not using the optical connections, it is
recommended that you turn them off (as provided
in the menus) to reduce bandwidth and processing
overhead. Note that you can operate the input and
output independently. For example, you could use
the ADAT optical format on the input (with a
digital mixer, for example) and optical S/PDIF on
the output (with a DAT deck, for example).
When the optical output is set to TOSLink, the
signal is split to both the RCA and optical output
jacks. However, when the optical input is set to
TOSLink, the RCA S/PDIF jack is disabled.
Phones
The Phones setting lets you choose what you will
hear from the headphone jack. Choose Analog 1-2
if you’d like the headphone output to match the
main outs. Choose Phones 1-2 if you would like the
headphones to serve as their own independent
output, which you can access as an independent
output destination in your host audio software and
as an output destination for the four on-board
CueMix DSP mix busses.
At the 4x sample rates (176.4 and 192kHz), the
headphone output can be assigned to any analog
output pair or the Phones 1-2 setting, as described
above. But at the 4x sample rates, the Phones
output is not available as an output destination for
software on the computer. Instead, it is only
available as a destination for the two CueMix DSP
mixes. In other words, it can only take CueMix
inputs.
reduces the word clock output to the
corresponding 1x rate (either 44.1 or 48kHz). For
example, if the Traveler is operating at 176.4kHz,
choose Force 44.1/48kHz to produce word clock
output at 44.1kHz.
To match the Traveler’s sample rate, choose System
Clock. To reduce the word clock rate to the
corresponding 1x rate, choose Force 44.1/48kHz.
Wave support for legacy (MME) software
Windows only exposes the first two channels of a
multi-channel WDM audio stream to applications
which use the legacy (MME) multimedia interface.
The Enable full Wave support for legacy (MME)
software (less efficient) option forces the Traveler
multimedia driver to expose all channels as stereo
pairs, providing full MME support.
If your host audio software does not directly
support WDM audio and instead only supports
legacy MME drivers, use this option to access
multiple Traveler input and output channels.
If your host audio software does directly support
WDM audio, leave this option unchecked for
optimal performance.
This option is only available when the multimedia
driver has been installed, and it defaults to being
not checked.
Word Out
If you are running a Traveler interface at a high
sample rate (88.2, 96, 176.4 or 192kHz), the Word
Out menu appears in the interface tab (as shown in
Figure 5-1 on page 40). This menu lets you choose
a word clock output rate that either matches the
global sample rate (e.g. 176.4 or 192kHz) or

In setup mode, the LCD displays basic settings,
such as clock source, optical I/O format (ADAT
versus TOSLink), and so on. These settings are
covered in detail later in “SETUP / SELECT” on
page 46.
VOLUME
The VOLUME knob lets you control the volume of
both the headphone jack and the rear-panel main
outs. Press the knob to toggle between the
headphones and the main outs. As explained in the
previous section, the LCD provides detailed
feedback as you turn the knob. To view the current

top row of the LCD and the current setting in the bottom row.
Mixer mode
In mixer mode, the LCD displays the settings for
the current Traveler mix being shown in the
display, as demonstrated in Figure 6-1 on page 45.
Parameter “zooming”
For many settings, the LCD temporarily “zooms
in” to display a long-throw meter and alphanumeric display to give you precise, real-time
feedback as you adjust the setting. For example, if
you change the headphone volume, the LCD will
display a level meter and gain reduction reading
that updates as you turn the volume knob. After a
brief time-out, the display returns to its previous
state before you turned the volume knob. The
time-out period can be adjusted, as explained later
in the section called “Fader View Time”.
Figure 6-3: For many settings, the LCD “zooms in” on the setting as
you adjust it.
Press the MIX/SETUP knob to toggle between
mixer mode and setup mode. In mixer mode, the
SETUP and SELECT knob do nothing. In setup
mode, turn SETUP to choose a setting and
SELECT to change it. In some cases, SELECT
chooses one of the Traveler’s four mixes, and the
VALUE knob changes the setting. The setup
settings are briefly explained below.
Clock source
This sets the global clock source for the Traveler
and is the same as the Clock Source setting in the
MOTU FireWire Audio Console as explained in
“Clock Source” on page 40. If the Traveler is
currently connected to a computer, this setting
cannot be changed from the front-panel LCD. It
must be changed in the MOTU FireWire Audio
Console instead. Or, you can disconnect the
Traveler from the computer to change the Clock
Source from the front panel.
Word Clock Out
If you are running a Traveler interface at a high
sample rate (88.2, 96, 176.4 or 192kHz), the Word
Clock Out setting lets you choose a word clock
output rate that either matches the global sample
rate (e.g. 176.4 or 192kHz) or reduces the word
clock output to the corresponding 1x rate (either
44.1 or 48kHz). To match the Traveler’s sample
rate, choose Follows System. To reduce the word
clock rate to the corresponding 1x rate, choose
Force 44/48.

Fader View Time
The Fader View Time option lets you control the
length of time that an adjusted parameter remains
displayed in the LCD before the LCD returns to its
previous state. For example, when you turn the
MIX BUS knob to adjust the volume of the current
mix, you’ll see a long-throw horizontal fader in the
LCD, along with a numeric display of the current
gain reduction. After you stop turning the knob,
this fader remains displayed in the LCD for a
moment before the LCD returns to its previous
state. The Fader View Time option lets you control
how long the adjusted parameter remains on the
LCD after the knob stops turning.
Optical In / Optical Out
These two settings determine the format for the
Traveler’s optical input and output. They are the
same as the optical setting in the MOTU FireWire
Audio Console as explained in “Optical input/
output” on page 43. To change the setting, turn the
SELECT knob, and then push it to confirm your
choice.
Bus output
The Bus Output setting lets you choose the Traveler
output pair for each of the four CueMix DSP mix
busses. Turn the SELECT knob to choose a bus.
Turn the VALUE knob to choose an output. Push
the VALUE knob to select the output. The output
stops flashing to confirm that it has been selected.
Bus mute
The Bus Mute setting mutes and unmutes the bus
output. Turn the SELECT knob to choose a bus.
Push the SELECT knob to mute or unmute the bus.
Phones Assign
The Phones Assign setting lets you choose what you
hear on the headphone output. This is the same as
the Phones setting in the MOTU FireWire Audio
Console as explained in “Phones” on page 44.
Init Current Mix
The Init Current Mix setting lets you reset the
current mix (or all four mixes). All inputs get reset
to unity gain (0 dB), pan center, etc.
Copy Bus Mix
Copy Bus Mix lets you copy all of the settings for the
currently displayed mix. Turn the SELECT knob to
choose a mix. Push the SELECT knob to copy it.
You can then paste the settings to another mix as
explained below. The word Done appears briefly to
confirm that the mix settings have been
successfully copied.
Paste Bus Mix
After you copy mix settings (explained above),
Paste Bus Mix lets you paste the copied mix settings
to another mix. Turn the SELECT knob to choose a
mix. Push SELECT to paste. The word Done
appears briefly to confirm the paste. The following
mix parameter are included in the paste operation:
Gain, Pan, Solo, Mute, +4/-10, +6dB boost, and
stereo pairing. The following mix parameters are
not pasted: Bus output, Bus mute and Bus gain.
Save/Name Preset
The Save/Name Preset setting lets you name and
save up to sixteen separate Traveler presets. A
preset holds all of the current CueMix DSP mix
settings for all four mix busses. Setup parameters
are not included. The name can have up to 12

Load preset
After you’ve saved one or more presets, Load Preset
lets you recall them. Turn the SELECT knob to
choose a preset. Push SELECT to load it. The word
Loaded appears briefly to confirm the operation.
All Notes Off
The All Notes Off setting sends a MIDI All Notes Off
message, as well as a MIDI note-off message for
every note on every MIDI channel. This stops any
stuck notes that are currently playing. Push
SELECT to initiate the All Notes Off operation. The
MIDI OUT LED will glow to confirm that the noteoff data is being sent.
Factory Defaults
The Factory Defaults setting restores the Traveler
factory settings. Before you can attempt this
operation, you must first quit all Windows audio
applications and all MOTU consoles (the MOTU
FireWire Audio Console, CueMix Console,
SMPTE console, etc.) Once you have done so, push
SELECT to initiate the operation, and then when
the LCD asks “Are you sure?”, push VALUE to
execute it. If any of the above-mentioned
applications are still running, the LCD will alert
you with the message saying that the Traveler is in
use by the CPU. Quit all audio software
applications and consoles and then try again.
MIX BUS
The Traveler on-board CueMix DSP mixer
provides four stereo mix busses, named MIX1,
MIX2, MIX3 and MIX4, respectively. Each mix bus
(also referred to as a “mix”) independently mixes
all inputs (or any subset of your choosing) down to
one Traveler output pair of your choosing. For
example, you could assign MIX1 to the main outs,
MIX2 to analog outputs 1-2 and MIX3 to the
headphone outs. You can then independently
assign any input to any mix. An input can even be
included in two or more mixes simultaneously at
different input levels.
Figure 6-4: In mixer mode, the LCD displays the mix settings for the
mix bus currently being displayed in the LCD.
When the LCD display is in mixer mode, push the
MIX BUS knob repeatedly to cycle through the
four mixes. The current mix is indicated in the
LCD above the MIX BUS label (as shown in
Figure 6-1 on page 45). Turn the MIX BUS knob to
change the output level for the mix.

PARAM
When the LCD display is in mixer mode, the
PARAM knob cycles through the mix parameters
listed below. Use the CURSOR knob to scroll to a
particular channel (until it flashes) and use the
VALUE knob to change its setting:
Mix
parameter Range
Comments
Gain
OFF,
-84 to 0 dB
Each channel displays a small fader.
Push the VALUE knob to toggle
between OFF and unity gain (0dB).
Pan
-64 to +64
Push the VALUE knob to jump to
pan center. Stereo pairs (explained
below) are panned hard left/right by
default.
Zero = pan
center
Solo
“s” or
blank
Push the VALUE knob to toggle
between soloed (S) and not soloed
(blank), or turn the knob to toggle.
Mute
“m” or
blank
Push the VALUE knob to toggle
between muted (m) and unmuted
(blank), or turn the knob to toggle.
4/10
down (+4)
or up (-10)
This setting applies universally
across ALL mix busses for analog
inputs 5-8. Push the VALUE knob to
toggle between a +4dB reference
level (down) and a -10dB reference
level (up). Or turn the knob to toggle.
+6db
“+” or 0
This setting applies universally
across ALL mix busses for analog
inputs 5-8. Push the VALUE knob to
toggle between a +6dB software
boost (+) and no boost (0). Or turn
the knob to toggle.
Pair
“[ ]” or
blank
This setting applies universally
across ALL mixes. Push the VALUE
knob to toggle a stereo input pair
between separate mono inputs
(blank) or a stereo pair (“[ ]”). Or
turn the knob to toggle. When a pair
of inputs are linked, all of their mix
settings become linked (gain, solo,
etc.) except for pan. When the pair is
first created, pan is set to hard left
and hard right, but the channels can
then be further modified independently. When a pair is unlinked, the
channels are set to pan-center.
Mix parameters that apply across all mixes
The last three mix settings (input reference level,
+6dB software boost, and stereo pairing) apply
across all mixes because they have to do with the
nature of the input itself. For example, if you have
an input that requires a -10dB reference level, then
you’ll want the reference level to apply to all mixes.
Working with stereo pairs
When you group a pair of inputs as a stereo pair, all
of their mix settings become linked, and whenever
you scroll to either channel, both channels will
flash to indicate that they will operate as a linked
stereo pair. Note that when a pair is first created,
pan is set to hard left and hard right, but the
channels can then be further modified independently. When a pair is unlinked, the channels are
set to pan-center.
CURSOR / VALUE
When the LCD display is in mixer mode, the
CURSOR knob scrolls left and right over the 20
inputs displayed in the LCD. The current input
flashes. As a shortcut, you can push the CURSOR
knob to toggle between the top row (analog inputs)
and bottom row (digital inputs). The VALUE knob
changes the current mix parameter for the
currently flashing input. In some cases, such as
Gain and Pan, the LCD will “zoom” to the enlarged
horizontal fader while you adjust it with the VALUE
knob. After you stop adjusting, the LCD will return
to the mixer display.
STAND-ALONE OPERATION
All settings, including all mix settings and global
settings, are saved in the Traveler’s memory, and
they remain in effect even when the Traveler is not
connected to a computer. This allows you to use the
Traveler as a stand-alone 8-bus mixer. You can
make adjustments to any setting at any time from
the front panel.

WHAT IS ASIO?
ASIO is an acronym for Audio Streaming Input and
Output. The ASIO MOTU FireWire Audio driver
allows the Traveler to provide multi-channel audio
input and output for any audio application that
supports ASIO drivers.
Sample-accurate sync
The MOTU FireWire Audio ASIO driver supports
sample-accurate sync (via the Traveler’s ADAT
sync feature) for applications that support it.
same and can be easily applied to any ASIOcompatible software. Just follow the general
descriptions at the beginning of each main section
in this chapter. Consult your software
documentation for details about each topic, if
necessary.
If your audio software doesn’t support ASIO
If your host audio software does not support ASIO,
but instead supports WDM (or legacy Wave) audio
drivers, refer to the next chapter.
PREPARATION
To make sure that everything is ready for Cubase,
install Cubase first (if you haven’t already done so),
and then see these chapters before proceeding:
■ chapter 4, “Installing the Traveler Hardware”
(page 19).
■ chapter 3, “IMPORTANT! Run the Traveler
Software Installer First” (page 17)
RUN THE MOTU FIREWIRE AUDIO CONSOLE
Before you run Cubase, launch the MOTU
FireWire Audio Console to configure your Traveler
hardware. The MOTU FireWire Audio Console lets
you configure your audio interface, and it lets you
enable the desired inputs and outputs. Only
enabled inputs and outputs will be available to
Cubase, so this is an important step. For complete
details regarding the MOTU FireWire Audio
Console, see chapter 5, “MOTU FireWire Audio
Console” (page 39).
Attention: Other software users
The Traveler ASIO driver also provides multichannel I/O with any ASIO-compatible audio
software. Cubase is used for the examples in this
chapter. However, the basic procedures are the
51
!Traveler Manual/Win Page 52 Monday, November 29, 2004 3:50 PM
Clock Source
This setting is very important because it
determines which audio clock the Traveler will
follow.
If you do not have any digital audio connections to
your Traveler (you are using the analog inputs and
outputs only), and you will not be slaving Cubase
to external SMPTE time code, choose Internal.
If you are slaving the Traveler to the ADAT sync
Input connector, choose ADAT 9-pin.
If you are slaving the Traveler and Cubase to
SMPTE time code via the Traveler itself, choose
SMPTE and follow the directions in “Syncing to
SMPTE time code” on page 32.
☛
If you are using an ASIO host application
other than Cubase or Nuendo, it must support the
ASIO 2.0 sample-accurate positioning protocol in
order to support the Traveler’s direct SMPTE sync
(and sample-accurate sync) feature.
Figure 7-1: The MOTU FireWire Audio Console gives you access to all
of the settings in the Traveler hardware, including the clock source,
sample rate and optical I/O enable/disable.
For complete details about the Traveler settings, see
chapter 5, “MOTU FireWire Audio Console”
(page 39). The following sections provide a brief
explanation of each Traveler setting for use with
Cubase.
Sample rate
Choose the desired overall sample rate for the
Traveler system and Cubase. Newly recorded audio
in Cubase will have this sample rate.
Before running the Traveler at the 4x sample rates,
see “Operation at 4x sample rates (176.4 or
192kHz)” on page 40.
If you have digital audio devices connected to the
Traveler, or if you are not sure about the clock
source of your setup, be sure to read “Making sync
connections” on page 27 and “Clock Source” on
page 40.
Samples Per Buffer
The Samples Per Buffer setting can be used to
reduce the delay — or monitoring latency — that
you hear when live audio is patched through your
Traveler hardware and Cubase. For example, you
might have MIDI instruments, samplers,
microphones, and so on connected to the analog
inputs of the Traveler. If so, you will often be
mixing their live input with audio material
recorded in Cubase. See chapter 9, “Reducing
Monitoring Latency” (page 65) for complete
details.
52
CUBASE, NUENDO AND OTHER ASIO SOFTWARE
!Traveler Manual/Win Page 53 Monday, November 29, 2004 3:50 PM
Optical input and output
To make a Traveler optical input or output available
in Cubase, choose the appropriate format (ADAT
optical or TOSLink) from the optical input and/or
output menu. If you won’t be using the optical
connectors, turn them off.
Phones
This Traveler setting lets you choose what you’ll
hear from the headphone jack. For example, if you
choose Analog 1-2, the headphones will duplicate
the main outs. Or you can choose any other output
pair. If you choose Phones, this setting makes the
headphone jack serve as its own independent
output pair. As a result, you’ll see Phones 1-2 as an
additional audio destination in Cubase’s audio
output menus.
CHOOSING THE MOTU FIREWIRE ASIO
DRIVER
Once you’ve made the preparations described so
far in this chapter, you’re ready to run your audio
software and enable the MOTU FireWire ASIO
driver. Check the audio system or audio hardware
configuration window in your software. There will
be a menu there that lets you choose among
various ASIO drivers that may be in your system.
Choose the MOTU FireWire ASIO driver from this
menu.
Nuendo and Cubase SX
To activate the Traveler driver in Nuendo or Cubase
SX, go to the Device Setup window, click VST
Audiobay and choose MOTU FireWire Audio from
the Master ASIO Driver menu as shown below.
Make the other settings in the dialog as need for
your system and synchronization scenario.
Figure 7-2: Activating the Traveler FireWire ASIO driver in Nuendo and
Cubase.
ASIO DIRECT MONITORING
The Direct Monitoring option (Figure 7-2) allows
you to monitor inputs directly in the Traveler
hardware with no drain on your computer and
near zero latency. When you enable this option,
Cubase uses the Traveler’s CueMix DSP
monitoring features whenever you use Cubase’s
monitoring features. For further information, see
“Controlling CueMix DSP from within Cubase or
Nuendo” on page 69.
OTHER SYSTEM DIALOG SETTINGS
Consult your Cubase or Nuendo documentation
for details about the rest of the settings in this
dialog.
VIEWING AND MANAGING TRAVELER
INPUTS
Once you’ve chosen the MOTU FireWire Audio
driver in the Audio System dialog as explained
earlier, click VST Inputs beneath the MOTU
FireWire Audio item (Figure 7-3). The list on the
right displays inputs supplied by the Traveler, as
well as any other connected MOTU FireWire audio
interfaces. If the list does not match what you
expect to see, click the Reset button. If you don’t see
the Traveler’s optical inputs and/or outputs in the
list, check the MOTU FireWire Audio Console to
make sure they are turned on and set to the format
you require. If you don’t plan to use the optical
input or output, turn it off to conserve computer
bandwidth.
53
CUBASE, NUENDO AND OTHER ASIO SOFTWARE
!Traveler Manual/Win Page 54 Monday, November 29, 2004 3:50 PM
VIEWING AND MANAGING TRAVELER
OUTPUTS
To view and manage Traveler outputs, click VST
Outputs beneath the MOTU FireWire Audio item
(Figure 7-4).
Figure 7-3: Creating Traveler inputs in Nuendo or Cubase SX.
The “Mix1 1-2” input
In Cubase’s VST Inputs list, you’ll see a Traveler
input called Mix1 1-2. This input source delivers
the output of CueMix DSP “MIX1” (the first mix
bus of the four on-board no-latency monitor mixes
in the Traveler) back to your computer. This input
serves, for example, as a convenient way for you to
record the Traveler’s MIX1 monitor mix back into
Cubase (for reference and archiving purposes).
Further, if you are sending audio from Cubase to
the same output pair as MIX1, you can choose to
either include or exclude the audio from the
computer in the stream being sent back to Cubase.
For details on how to do this, see “Mix1 Return
Includes Computer” on page 76.
The Mix1 1-2 input is not available at the 4x sample
rates (176.4 or 192kHz).
☛ Warning: the Mix1 1-2 input can cause
feedback loops! DO NOT assign this input to a
track that shares the same Traveler output pair as
MIX1.
Figure 7-4: Working with Traveler outputs in Nuendo or Cubase.
The “Phones 1-2” output
If you’ve chosen to treat the Traveler headphones as
an independent output, you’ll see Phones 1-2 as a
Traveler output destination. Audio tracks assigned
to this output pair will be heard on the headphone
jack only. For further explanation, see “Phones” on
page 53.
CHANGING TRAVELER SETTINGS
To change the Traveler settings at any time, go to
the Device Setup window in Nuendo or Cubase SX
and click the ASIO Control Panel button, as shown
in Figure 7-2 on page 53. Be sure to click the Reset
button (as shown in Figure 7-3 and Figure 7-4)
after making any changes to the optical or phone
settings in the MOTU FireWire Audio Console.
PROCESSING LIVE INPUTS WITH PLUG-INS
If you patch a live input (such as MIDI synthesizer)
through a VST plug-in effect in Cubase, you might
hear a slight delay. There are several ways to reduce
this delay. For details, see chapter 9, “Reducing
Monitoring Latency” (page 65).
54
CUBASE, NUENDO AND OTHER ASIO SOFTWARE
!Traveler Manual/Win Page 55 Monday, November 29, 2004 3:50 PM
SYNCHRONIZATION
Cubase or Nuendo can run under its own transport
control or slave to SMPTE time code. It can also
perform sample-accurate digital audio transfers
with Alesis digital recorders and Tascam family
digital recorders.
As you read through the following sections to
decide what form of synchronization you might
need with other devices in your studio, be sure to
consult chapter 4, “Installing the Traveler
Hardware” (page 19) for the proper hardware
connections. Use the synchronization diagrams in
that chapter to be clear about how you will be
synchronizing Cubase to the other components of
your system.
Running Cubase or Nuendo under its own
transport control
If you do not need to synchronize Cubase or
Nuendo with time code or another recording
device, such as a tape deck, just leave its SMPTE
time code synchronization features disabled.
However, even though Cubase or Nuendo is not
slaving to SMPTE time code, you still need to be
concerned with the synchronization of the
Traveler’s digital audio clock with other devices
connected to it digitally (if any). For example, if
you have a digital mixer connected to a Traveler
interface via an ADAT optical lightpipe cable, you
need to make sure that their audio clocks are
phase-locked. For details, see “Syncing optical
devices” on page 34 and “Making sync
connections” on page 27. If you don’t have any
digital audio devices connected, digital audio
phase-lock does not apply to you.
Resolving Cubase or Nuendo and the Traveler
to SMPTE time code
If you need to slave Cubase or Nuendo and the
Traveler to SMPTE time code, you can do so with
or without a dedicated synchronizer.
Resolving directly to time code (with no
synchronizer)
To resolve your Traveler directly to SMPTE time
code with no additional synchronization devices,
use the setup shown in “Syncing to SMPTE time
code” on page 32. Make sure the Clock Source
setting in the MOTU FireWire Audio Console
window is set to SMPTE. Also, make sure that
you’ve connected an LTC input signal to a Traveler
analog input, and that you’ve specified that input in
the SMPTE Console.
Resolving to video and/or time code with a
dedicated synchronizer
To resolve your Traveler to video and/or SMPTE
time code using an additional synchronization
device, use the setup shown in “Syncing to video
and/or SMPTE time code using a synchronizer” on
page 33.
Follow the instructions in your Cubase or Nuendo
manual for slaving them to MIDI Time Code
(MTC). To ensure that your audio tracks don’t drift
out of sync with your MIDI tracks — or time code,
use a hardware synchronizer like the MIDI
Timepiece AV or Digital Timepiece to resolve the
Traveler hardware as well, as explained in “Syncing
to video and/or SMPTE time code using a
synchronizer” on page 33. A digital audio
synchronizer is required for drift-free SMPTE/
MIDI time code sync. Make sure the Clock Source
setting in the MOTU FireWire Audio Console
window has the appropriate setting for locking the
Traveler to the synchronizer. For example, in
Figure 4-20 on page 36, word clock is being used to
resolve a Traveler interface, so the Clock Source
setting is Word Clock In.
☛
If you have an ADAT sync or a Tascam sync
compatible device, don’t use SMPTE time code.
Instead, use sample-accurate sync as described in
the next section.
55
CUBASE, NUENDO AND OTHER ASIO SOFTWARE
!Traveler Manual/Win Page 56 Monday, November 29, 2004 3:50 PM
Sample-accurate sync to ADAT or Tascam
Cubase and Nuendo, along with the Traveler and
its ASIO 2 driver, provide you with sampleaccurate transfers with ADATs, Alesis recorders
and any other devices that support standard ADAT
sample address (ADAT Sync).
Similarly, with the help of a MOTU Digital
Timepiece universal A/V synchronizer, Cubase (or
Nuendo) and a Traveler can perform sampleaccurate transfers with Tascam digital recorders.
4 If you are using an MMC-compatible
synchronizer (such as a MOTU MIDI
Timepiece AV, Digital Timepiece or Alesis BRC),
enable Nuendo’s (or Cubase SX’s) MMC Active
option. In addition, choose the appropriate MIDI
port for the MMC synchronizer from the menu.
Doing so makes Cubase or Nuendo send the MMC
control messages to the MTP AV (or other MMC
device). In this scenario, transport control is
handled by Cubase or Nuendo itself.
A sample-accurate transfer is one in which the
original location of the audio is preserved in the
transfer, down to the sample.
For details on how to connect your hardware for
sample-accurate sync, see “Sample-accurate sync”
on page 29. Then, set up Cubase as follows:
1 Choose ADAT 9-pin as the Audio Clock Source
setting. In Nuendo or Cubase SX, this setting is in
the Device Setup window (Options menu).
Figure 7-6: Setting up sample-accurate sync via ASIO 2.
5 In Nuendo or Cubase SX, enable the Sync
button in the Transport menu.
2 Go to Cubase or Nuendo’s Synchronization
Setup window, as shown below:
Figure 7-7: Enabling the SYNC button.
6 If you don’t have an MMC synchronizer
(Figure 7-5), initiate playback from the sampleaccurate sync source (ADAT, DA-88, etc.)
Transport control is handled by the sampleaccurate sync source.
Figure 7-5: Setting up sample-accurate sync via ASIO 2.
3 If you are not using an MMC-compatible
synchronizer (such as a MOTU MIDI
Timepiece AV, Digital Timepiece or Alesis BRC),
leave the MMC Active box unchecked. In this
scenario, transport control is handled by the ADAT
(or other sample-accurate sync source).
7 If you do have an MMC synchronizer, begin
playback from Cubase, and the other device(s) will
follow.
56
CUBASE, NUENDO AND OTHER ASIO SOFTWARE
!Traveler Manual/Win Page 57 Monday, November 29, 2004 3:50 PM
MIDI MACHINE CONTROL (MMC)
24-BIT OPERATION
If you have ADATs (or other ADAT Synccompatible recorders) and a MMC-compatible
ADAT synchronizer like the MIDI Timepiece AV
and Digital Timepiece, you can control everything
from your computer screen with Cubase’s
transport controls and cueing features (like the
playback wiper, etc.)
Your Traveler hardware fully supports Cubase and
Nuendo’s 24-bit recording capabilities. Simply
enable 24-bit operation as instructed in your
Cubase or Nuendo manual. The Traveler always
supplies a 24-bit data stream, and when you enable
24-bit operation in Cubase or Nuendo, it simply
uses all 24-bits supplied by the Traveler hardware.
Similarly, if you have Tascam digital recorders and
a MOTU Digital Timepiece (or other MMCcompatible Tascam synchronizer), you can control
all of your Tascam tape decks (in ABS time) in a
similar fashion from Cubase.
MONITORING SYSTEM PERFORMANCE
See “Sample-accurate sync to ADAT or Tascam” on
page 56 for details on how to set this up.
MIDI I/O VIA THE TRAVELER MIDI PORTS
Once you’ve run the Traveler’s software installer as
explained in “Installing the Traveler software” on
page 17, the Traveler MIDI ports will appear as a
input source and output destination in the MIDI
input and output menus of your WDM-compatible
host software.
Because it has so many inputs and outputs, the
Traveler may push the limits of your computer’s
processing power. Keep the VST Performance
window open to keep tabs on the load on your CPU
and disk buffers. If the meters get too high, you can
reduce the load by reducing the number of inputs
and outputs you are working with. Use the MOTU
FireWire Audio Console to uncheck input check
boxes and set output source menus to None.
Figure 7-8: Keep the Audio Performance window open to keep tabs
on your computer’s processing power and hard disk performance.

Attention: other software users
Cakewalk’s SONAR software is used for the WDM
driver setup examples in this chapter. However, the
basic procedures are the same and can be easily
applied to any WDM-compatible software. Just
follow the general descriptions at the beginning of
each main section in this chapter. Consult your
software documentation for details about each
topic, if necessary.
INSTALLING THE MOTU FIREWIRE AUDIO
WDM DRIVER
The MOTU FireWire Audio Installer CD installs
the MOTU FireWire WDM driver into Windows
for you. That’s pretty much all the preparation you
need. See chapter 3, “IMPORTANT! Run the
Traveler Software Installer First” (page 17).
ENABLING WAVE (MME) COMPATIBILITY
If your host audio software does not yet support
Windows WDM drivers, enable Wave driver
compatibility in the MOTU FireWire WDM driver
so that all of the Traveler’s inputs and outputs show
up in your software. For details, see “Wave support
for legacy (MME) software” on page 44.
☛ If your host audio software does support
WDM audio drivers, don’t enable Wave driver
compatibility.

MAKING SETTINGS IN THE MOTU FIREWIRE
AUDIO CONSOLE
Before you run your audio software, launch the
MOTU FireWire Audio Console to configure your
Traveler hardware. The MOTU FireWire Audio
Console lets you choose the audio clock source,
and it lets you enable the optical input and output,
if needed. For details, see chapter 5, “MOTU
FireWire Audio Console” (page 39).
For complete details about the Traveler settings, see
chapter 5, “MOTU FireWire Audio Console”
(page 39). The following sections provide a brief
explanation of each Traveler setting for use with
Sonar.
Sample rate
Choose the desired overall sample rate for the
Traveler system and Sonar. Newly recorded audio
in Sonar will have this sample rate.
Before running the Traveler at the 4x sample rates,
see “Operation at 4x sample rates (176.4 or
192kHz)” on page 40.
Clock Source
This setting is very important because it
determines which audio clock the Traveler will
follow.
If you do not have any digital audio connections to
your Traveler (you are using the analog inputs and
outputs only), and you will not be slaving Sonar to
external SMPTE time code, choose Internal.
If you are slaving the Traveler to the ADAT sync
Input connector, choose ADAT 9-pin.
If you have digital audio devices connected to the
Traveler, or if you are not sure about the clock
source of your setup, be sure to read “Making sync
connections” on page 27 and “Clock Source” on
page 40.
Figure 8-1: The MOTU FireWire Audio Console gives you access to all
of the settings in the Traveler hardware, including the clock source,
sample rate and optical I/O enable/disable.
Samples Per Buffer
The Samples Per Buffer setting can be used to
reduce the delay — or monitoring latency — that
you hear when live audio is patched through your
Traveler hardware and Sonar. For example, you
might have MIDI instruments, samplers,
microphones, and so on connected to the analog
inputs of the Traveler. If so, you will often be
mixing their live input with audio material

recorded in Sonar. See chapter 9, “Reducing
Monitoring Latency” (page 65) for complete
details.
Optical input and output
To make a Traveler optical input or output available
in Sonar, choose the appropriate format (ADAT
optical or TOSLink) from the optical input and/or
output menu. If you won’t be using the optical
connectors, turn them off.
Phones
This Traveler setting lets you choose what you’ll
hear from the headphone jack. For example, if you
choose Analog 1-2, the headphones will duplicate
the main outs. Or you can choose any other output
pair. If you choose Phones, this setting makes the
headphone jack serve as its own independent
output pair. As a result, you’ll see Phones 1-2 as an
additional audio destination in Sonar’s audio
output menus.
ENABLING THE MOTU FIREWIRE AUDIO
WDM DRIVER
Once you’ve made the preparations described so
far in this chapter, you’re ready to run your audio
software and enable the MOTU FireWire Audio
WDM driver. Check the audio system or audio
hardware configuration window in your software.
Figure 8-2: Activating the MOTU FireWire Audio WDM driver in
SONAR by highlighting Traveler inputs and outputs.
Other audio settings in SONAR
There are a few other settings in SONAR that
impact Traveler operation:
1 In the Audio Options window, click the General
tab.
2 Choose a Traveler input and output for
recording and playback timing as shown below in
Figure 8-3. It doesn’t matter which input or output
you choose.
Enabling the MOTU FireWire Audio WDM
driver in SONAR
To activate the MOTU FireWire Audio WDM

OTHER AUDIO OPTIONS
Consult your sonar documentation for details
about the rest of the settings in this dialog.
WORKING WITH TRAVELER INPUTS AND
OUTPUTS
Once you’ve enabled the Traveler inputs and
outputs in the Drivers tab of the Audio Options
window (Figure 8-2 on page 61), Traveler audio
inputs and outputs will appear in Sonar’s input/
output menus, and you can set them up and use
them as any standard audio input and output. If
you don’t see the optical inputs and/or outputs,
check the MOTU FireWire Audio Console to make
sure they are turned on and set to the format you
need. If you don’t plan to use the optical input or
output, turn it off to conserve computer
bandwidth.
The “Mix1 1” input
In Sonar’s Input Drivers list, you’ll see a Traveler
input called Mix1 1-2. This input source delivers
the output of CueMix DSP “MIX1” (the first mix
bus of the four on-board no-latency monitor mixes
in the Traveler) back to your computer. This input
serves, for example, as a convenient way for you to
record the Traveler’s MIX1 monitor mix back into
Sonar (for reference and archiving purposes).
Further, if you are sending audio from Sonar to the
same output pair as MIX1, you can choose to either
include or exclude the audio from the computer in
the stream being sent back to Sonar. For details on
how to do this, see “Mix1 Return Includes
Computer” on page 76.
The Mix1 1-2 input is not available at the 4x sample
rates (176.4 or 192kHz).
☛ Warning: the Mix1 1-2 input can cause
feedback loops! DO NOT assign this input to a
track that shares the same Traveler output pair as
MIX1.
The “Phones 1-2” output
If you’ve chosen to treat the Traveler headphones as
an independent output, you’ll see Phones 1-2 as a
Traveler output destination. Audio tracks assigned
to this output pair will be heard on the headphone
jack only. For further explanation, see “Phones” on
page 44.
CHANGING TRAVELER SETTINGS
You can change the Traveler settings at any time by
accessing the MOTU FireWire Audio Console.
REDUCING DELAY WHEN MONITORING
LIVE INPUTS
If you have live audio inputs connected to the
Traveler, such as MIDI synthesizers, samplers,
microphones or other live instruments, you might
hear a slight delay when their audio is being
monitored through your Traveler hardware and
your host audio program. There are several ways to
reduce — and eliminate — this audible monitoring
delay. For details, see chapter 9, “Reducing
Monitoring Latency” (page 65).
SYNCHRONIZATION
If your audio software has the ability to slave to
SMPTE time code, then it can take advantage of the
synchronization features in the Traveler.
As you read through the following sections to
decide what form of synchronization you might
need with other devices in your studio, be sure to
consult “Making sync connections” on page 27 for
62
SONAR AND OTHER WDM SOFTWARE
!Traveler Manual/Win Page 63 Monday, November 29, 2004 3:50 PM
the proper hardware connections. Use the
synchronization diagrams to be clear about how
you will be synchronizing your audio software and
the Traveler to the other components of your
system.
Synchronizing digital audio connections
If you have devices connected to the Traveler
digital inputs (optical or RCA S/PDIF), you need to
be concerned with the synchronization of the
Traveler’s digital audio clock with other devices
connected to it digitally (if any). For example, if
you have a digital mixer connected to the Traveler
via an ADAT optical light pipe cable, you need to
make sure that their audio clocks are phase-locked.
For details, see “Syncing optical devices” on
page 34 and “Making sync connections” on
page 27. If you don’t have any digital audio devices
connected to the Traveler, digital audio phase-lock
does not apply to you.
Slaving to SMPTE time code
If you need to slave your audio software and the
Traveler system to SMPTE time code, follow the
instructions in your software’s manual for slaving it
to MIDI Time Code (MTC). To ensure that your
audio tracks don’t drift out of sync with your MIDI
tracks or the time code, use a hardware
synchronizer like the MOTU MIDI Timepiece AV
or Digital Timepiece to slave the Traveler hardware
to the SMPTE (or MIDI Time) Code as well. A
digital audio synchronizer is required for drift-free
SMPTE/MIDI time code sync. Make sure the Clock
Source setting in the MOTU FireWire Audio
Console is set to Word Clock In. For examples of
how to set this up, see “Syncing to video and/or
SMPTE time code using a synchronizer” on
page 33.
MIDI I/O VIA THE TRAVELER MIDI PORTS
Once you’ve run the Traveler software installer as
explained in “Installing the Traveler software” on
page 17, the Traveler MIDI ports will appear as a
MIDI input source and output destination in
Sonar’s MIDI I/O menus.
24-BIT OPERATION
Your Traveler hardware fully supports 24-bit
recording in any audio software that supports it.
Simply enable 24-bit operation as instructed by the
software. The Traveler system always supplies the
software with a 24-bit data stream, and when you
enable 24-bit operation, it simply uses all 24-bits
supplied by the Traveler hardware.

CHAPTER 9
Reducing Monitoring Latency
OVERVIEW
Monitoring latency is that slight delay you hear
when you run an input signal through your host
audio software. For example, you might hear it
when you drive a live mic input signal through a
reverb plug-in running in your audio sequencer.
This delay is caused by the amount of time it takes
for audio to make the entire round trip through
your computer, from when it first enters a Traveler
input, passes through the Traveler hardware into
the computer, through your host audio software,
and then back out to a Traveler output.

Controlling CueMix DSP from your audio software . . 69
If you don’t need to process a live input with
plug-ins, the easiest way to avoid monitoring
latency is to use the Traveler’s CueMix DSP feature
to patch the input directly to your monitor outs via
the Traveler audio hardware. This is just like
bussing inputs to outputs in a digital mixer. For
details, see “CueMix DSP hardware monitoring”
on page 68.
If you do need to process a live input with plug-ins,
or if you are playing virtual instruments live
through your Traveler audio hardware, you can
significantly reduce latency — and even make it
completely inaudible, regardless of what host audio
application software you use. This chapter explains
how.
It is important to note that monitoring delay has no
effect on when audio data is recorded to disk or
played back from disk. Actual recording and
playback is extremely precise.
65
!Traveler Manual/Win Page 66 Monday, November 29, 2004 3:50 PM
MONITORING LIVE INPUT
There are two ways to monitor live audio input
with a Traveler: 1) through the computer or 2) via
CueMix™ DSP hardware monitoring. Figure 9-1
on page 66 shows method 1, which allows you to
add effects processing such as reverb and guitar
amp effects via plug-ins in your audio software. See
the next section, “Adjusting the audio I/O buffer”
for details about how to reduce — and possibly
eliminate — the audible monitoring delay that the
computer introduces.
monitoring” later in this chapter for details on how
to use CueMix DSP with your audio software, or
with the included CueMix Console software.
If the material you are recording is suitable, there is
a third way to monitor live input: use both methods
(Figure 9-1 and Figure 9-2) at the same time. For
example, you could route vocals to both the
computer (for a bit of reverb) and mix that
processed signal on the main outs with dry vocals
from CueMix DSP.
Figure 9-2 shows how to use CueMix™ DSP
hardware-based monitoring, which lets you hear
what you are recording with no monitoring delay
and no computer-based effects processing. (You
can add effects later, after you’ve recorded the live
input as a disk track.) See “CueMix DSP hardware
1. Live input (from mic, guitar, etc.)
enters the MOTU interface.
3. Mic signal is
‘patched thru’ back to

with reverb or other
plug-in effects, if any.
2. Mic signal goes immediately to the computer (dry,
with no effects processing).

4. Mic signal (with plug-in
processing, if any) is routed
to the main outs (or other
outputs that you’ve specified
in the software).
Figure 9-1: There are two ways to monitor live audio inputs with a Traveler: 1) through the computer or 2) via CueMix™ DSP hardware
monitoring. This diagram shows method 1 (through the computer). When using this method, use your host software’s buffer setting to reduce
the slight delay you hear when monitoring the live input, but don’t lower it too much, or your computer might get sluggish.
66
REDUCING MONITORING LATENCY
!Traveler Manual/Win Page 67 Monday, November 29, 2004 3:50 PM
ADJUSTING THE AUDIO I/O BUFFER
A buffer is a small amount of computer memory
used to hold data. For audio interfaces like the
Traveler, buffers are used for the process of
transferring audio data in and out of the computer.
The size of the buffers determines how much delay
you hear when monitoring live inputs through
your audio software: larger buffers produce more
delay; smaller buffers produce less.
Buffer size adjustment is made in the MOTU
FireWire Audio Console, as shown in Figure 9-3
via the Samples Per Buffer setting.
Figure 9-3: Lowering the ‘Samples Per Buffer’ setting in the MOTU
FireWire Audio Console Window reduces patch thru latency. But
doing so increases the processing load on your computer, so keep an
eye on the Performance Monitor in your host audio software.
1. Live input (from mic, guitar, etc.)
enters the MOTU interface.
3. Mic signal is mixed with the
main outs, and you can control
the volume (relative to the rest
of the mix) with the mic’s fader
in CueMix Console.
2. CueMix™ DSP immediately
patches the live mic signal directly
to the main outs (or other output),
completely bypassing the computer
(dry, with no effects processing).
Figure 9-2: This diagram shows the signal flow when using CueMix™ DSP no-latency monitoring. Notice that this method does not allow you
to process the live input with plug-ins in your audio software while it is being monitored. You can, however, add effects later — after recording
the live input as a disk track. CueMix™ DSP lets you hear what you are recording with no delay and no computer-based effects.

REDUCING MONITORING LATENCY
!Traveler Manual/Win Page 68 Monday, November 29, 2004 3:50 PM
Lower latency versus higher CPU overhead
The buffer setting has a large impact on the
following things:
■
Patch thru latency
■
The load on your computer’s CPU
■
Possible distortion at the smallest settings
■ How responsive the transport controls are in
your audio software
The buffer setting presents you with a trade-off
between the processing power of your computer
and the delay of live audio as it is being patched
through your software. If you reduce the size, you
reduce patch thru latency, but significantly increase
the overall processing load on your computer,
leaving less CPU bandwidth for things like realtime effects processing. On the other hand, if you
increase the buffer size, you reduce the load on
your computer, freeing up bandwidth for effects,
mixing and other real-time operations.
If you are at a point in your recording project where
you are not currently working with live, patchedthru material (e.g. you’re not recording vocals), or
if you have a way of externally processing inputs,
choose a higher buffer size. Depending on your
computer’s CPU speed, you might find that settings
in the middle work best (256 to 1024).
Transport responsiveness
Buffer size also impacts how quickly your audio
software will respond when you begin playback,
although not by amounts that are very noticeable.
Lowering the buffer size will make your software
respond faster; raising the buffer size will make it a
little bit slower, but barely enough to notice.
Effects processing and automated mixing
Reducing latency with the buffer size setting has
another benefit: it lets you route live inputs through
the real-time effects processing and mix
automation of your audio software.
CUEMIX DSP HARDWARE MONITORING
The Traveler has a more direct method of patching
audio through the system. This method is called
CueMix DSP. When enabled, CueMix activates
hardware patch-thru in the Traveler itself. CueMix
DSP has two important benefits:
■ First, it completely eliminates the patch thru
delay (reducing it to a small number of samples —
about the same amount as one of today’s digital
mixers).
■ Secondly, CueMix DSP imposes no strain on the
computer.
The trade-off, however, is that CueMix DSP
bypasses your host audio software. Instead, live
audio inputs are patched directly through to
outputs in the Traveler itself and are mixed with
disk tracks playing back from your audio software.
This means that you cannot apply plug-ins, mix
automation, or other real-time effects that your
audio software provides. But for inputs that don’t
need these types of features, CueMix DSP is the
way to go.
On the other hand, if you really need to use the
mixing and processing provided by your audio
software, you should not use CueMix DSP. Instead,
reduce latency with the buffer setting (as explained
earlier in this chapter).
TWO METHODS FOR CONTROLLING
CUEMIX DSP
There are two ways to control CueMix DSP:
■
With CueMix Console
■ From within your host audio software (if it
supports direct hardware monitoring)
You can even use both methods simultaneously.
68
REDUCING MONITORING LATENCY
!Traveler Manual/Win Page 69 Monday, November 29, 2004 3:50 PM
Using CueMix Console
If your host audio software does not support direct
hardware monitoring, you run CueMix Console
side-by-side with your audio software and manage
your monitor mix in CueMix Console.
CueMix Console allows you to create up to four
separate Traveler monitor mixes, or any other
desired routing configurations. These routings are
independent of your host audio software. For
complete details, see chapter 10, “CueMix
Console” (page 71).
Controlling CueMix DSP from your audio
software
Some ASIO-compatible audio applications, such as
Cubase and Nuendo, allow you to control CueMix
DSP monitoring from within the application
(without the need to use CueMix Console). In
most cases, this support consists of patching a
Traveler input directly to an output when you
record-arm a track. Exactly how this is handled
depends on the application.
CueMix DSP routings that are made via host
applications are made “under the hood”, which
means that you won’t see them in CueMix Console.
However, CueMix DSP connections made inside
your host audio software dovetail with any other
mixes you’ve set up in CueMix Console. For
example, if your host application routes audio to an
output pair that is already being used in CueMix
Console for an entirely separate mix bus, both
audio streams will simply be merged to the output.
Follow the directions below in the section that
applies to you.
Controlling CueMix DSP from within Cubase or
Nuendo
To turn on CueMix in Cubase SX or Nuendo,
enable the Direct Monitoring check box in the
Device Setup window (Figure 7-2 on page 53).
Other ASIO 2.0-compatible host software
If your ASIO-compatible host audio software
supports ASIO’s direct monitoring feature, consult
your software documentation to learn how to
enable this feature. Once enabled, it should work
similarly as described for Cubase (as explained in
the previous section).
Using CueMix DSP with WDM- or Wavecompatible software
Run CueMix Console (chapter 10, “CueMix
Console” (page 71)) and use it to route live inputs
directly to outputs, control their volume and
panning, etc. If necessary, you can save your
CueMix Console setup with your project file.

CHAPTER 10
CueMix Console
OVERVIEW
CueMix Console provides access to the flexible
on-board mixing features of the Traveler. CueMix
lets you route any combination of inputs to any
stereo output pair. These mixes can be set up
entirely independently of your host audio software.
CueMix allows you to set up four completely
independent mix configurations with the Traveler.
You can also save and load mix configurations.
CueMix Console can be used independently of
host audio software, or together with it. CueMix
mixing dovetails with the direct monitoring
(hardware patch thru) features of your host audio
software, allowing you to seemlessly mix in both
environments.

ADVANTAGES OF CUEMIX MONITORING
CueMix Console provides several major
advantages over monitoring live inputs through
your host audio software:
CueMix has no buffer latency. Thanks to the
Traveler’s DSP chip, CueMix provides the same
throughput performance as a digital mixer.
■
CueMix imposes absolutely no processor drain
on the computer’s CPU.
■
■ CueMix routing can be maintained
independently of individual software applications
or projects.
CueMix routing can operate without the
computer, allowing the Traveler to operate as a
portable, stand-alone mixer.
■
CueMix Console does not provide effects
processing. For information about using your
audio software’s native plug-ins together with
CueMix, see chapter 9, “Reducing Monitoring
Latency” (page 65).
CUEMIX CONSOLE INSTALLATION
CueMix Console is installed with the rest of your
Traveler software.
CUEMIX CONSOLE BASIC OPERATION
The CueMix console is simple to operate, once you
understand these basic concepts.
Four mixes
CueMix provides four separate mixes: Mix1, Mix2,
Mix3 and Mix4. Each mix can have any number of
inputs mixed down to any Traveler output pair that
you choose. For example, Mix1 could go to the
headphones, Mix2 could go to the main outs, Mix3
could go to a piece of outboard gear connected to
analog outputs 7-8, etc.
Many inputs to one output pair
It might be useful to think of each mix as some
number of inputs all mixed down to a stereo output
pair. CueMix Console lets you choose which inputs
to include in the mix, and it lets you specify the
level and pan for each input being fed into the mix.
Viewing one mix at a time
CueMix Console displays one mix at a time. To
select which mix you are viewing, click its tab at the
bottom of the window, as shown in Figure 10-1.
The mix name appears in the tab. Double-click the
name to change it.
Each mix is completely independent
Each mix has its own settings. Settings in one mix
will not affect another. For example, if an input is
used in one mix, it will still be available in other
mixes. In addition, inputs can have a different
volume, pan, mute and solo setting in each mix.
Some channel settings apply across all mixes
The settings at the top of the CueMix Console
window (above the channel section) apply to all
mixes. These settings include the preamp gain and
pad for the four mic inputs, and the +4/-10dB
reference level and +6dB software boost for analog
inputs 5-8.
Widening the CueMix Console window
To view more input faders at once, drag the righthand edge of the window to the right.
WORKING WITH A MIX
Each mix has the following components:
■
A stereo output with master fader
■
Name
■
Master mute (to enable/disable the entire mix)
■
Any number of mono or stereo inputs
■
Pan, volume, mute and solo for each input

PREAMP GAIN, PAD, REFERENCE LEVEL AND
+6DB BOOST
SAVING AND LOADING PRESETS TO/FROM
DISK
The preamp gain, pad, reference level and +6dB
boost settings at the very top of the CueMix
Console window (Figure 10-1) affect each input
globally, across all mixes and for audio being
routed to the computer. For example, if you add
6dB of boost, your host software will receive the
boost for that input as well.
The Save and Load commands in the CueMix
Console File menu allow you to save Traveler
presets to and from your hard drive. This allows
you to save an unlimited number of Traveler
presets on disk. (Use the Load Preset and Save
Preset commands to get presets from — and save

Preamp gain
This setting (Figure 10-1) adjusts preamp gain, just
like the four trim knobs on the front panel of the
Traveler.
Pad
These buttons (Figure 10-1) toggle the pad for each
mic input. Clicking these buttons is the same as

Click the reference button to toggle between these
two standard reference levels. This setting is
applied globally for the input pair.
SAVING AND LOADING PRESETS
As explained earlier in “Save/Name Preset” on
page 47, the Traveler can store up to 16 presets in its
on-board memory. A preset includes of all CueMix
DSP settings for all four mix busses, but it excludes
global settings like clock source and sample rate.
TALKBACK AND LISTENBACK
CueMix Console provides Talkback and Listenback
buttons. Talkback allows an engineer in the control
room to temporarily dim all audio and talk to
musicians in the live room. Conversely, Listenback
allows musicians to talk to the control room.
Hardware setup
Figure 10-2 below shows a typical hardware setup
for Talkback and Listenback. For Talkback, set up a
dedicated mic in your control room and connect it
to a mic input on your MOTU FireWire audio
interface. For Listenback, set up a dedicated
listenback mic in the live room for the musicians
and connect it to another mic input. For talkback
output, set up a headphone distribution amp or set
of speakers in the live room, and connect it to a pair
of outputs. For example, you might connect a
headphone distribution amp to analog outputs 7-8
on your MOTU Firewire audio interface, as
demonstrated below in Figure 10-2 on page 75.
The Load Preset and Save Preset commands in the
CueMix Console File menu let you name, save and
load presets in the Traveler.

Controlling Talkback and Listenback volume
To control the volume of the Talkback and/or
Listenback mics, adjust their input fader in CueMix
Console. This fader controls the volume of the
input, regardless of which bus mix is being
displayed in the CueMix Console window. In other
words, once an input has been designated as a
Talkback or Listenback input, its fader becomes
global for all CueMix buses.
MIX1 RETURN INCLUDES COMPUTER
The Mix1 return includes computer item in the
CueMix Console File menu refers to the Mix1 bus
that the Traveler driver provides as an input to host
audio software. This input source delivers the
output of CueMix DSP “MIX1” (the first mix bus of
the four on-board no-latency monitor mixes in the
Traveler) back to your computer. This input serves,
for example, as a convenient way for you to record
The Phones menu allows you to choose what you
will hear on the headphone output, just like the
Phones setting the MOTU FireWire Audio
Console. However, this menu provides one extra
option that is exclusive to CueMix Console: Follow
Active Mix. This menu item, when checked, causes
the headphone output to mirror the output of the
current mix being viewed in CueMix Console. For
example, if you are currently viewing Mix3 (the
Mix3 tab is active), the headphones will mirror the
Mix3 output (whatever it is assigned to).
CONTROL SURFACES MENU
CueMix Console can be controlled from an
automated control surface such as the Mackie
Control™. Use the commands in the Control
Surfaces menu to enable and configure this feature.
Application follows control surface
When checked, the Application follows control
surface menu command makes the CueMix
Console window scroll to the channel you are
currently adjusting with the control surface, if the
channel is not visible when you begin adjusting it.
The same is true for the bus tabs: if you adjust a
control in a bus that is not currently being

appropriate tab to display the control you are
adjusting.
Share surfaces with other applications
When the Share surfaces with other applications
menu command is checked, CueMix Console
releases the control surface when you switch to
another application. This allows you to control
your other software with the control surface. Here’s
a simple way to understand this mode: the control
surface will always control the front-most
application. Just bring the desired application to
the front (make it the active application), and your
control surface will control it. When you’d like to
make changes to CueMix Console from the control
surface, just bring CueMix Console to the front
(make it the active application).
Enabled
Check this menu item to turn on control surface
operation of CueMix Console. Uncheck it to turn
off control surface support.
Configure…
Choose this menu item to configure your control
surface product. Launch the on-line help for
specific, detailed instructions for configuring
CueMix Console for operation with your control
surface product.
When this menu item is unchecked, your control
surface will affect CueMix Console all the time,
even when CueMix Console is not the front-most
application. In addition, you will not be able to
control other host audio software with the control
surface at any time (because CueMix Console
retains control over it at all times). This mode is
useful when you do not need to use the control
surface with any other software.

CUEMIX CONSOLE EXAMPLES
Figure 10-7 below shows some examples of how
you can use CueMix DSP:
Powered speakers are connected to the Traveler
main outs. Any input can be routed directly to the
speakers.
■
Microphone input can be routed via CueMix
DSP to the effects processor for live outboard
processing during recording. The resulting signal
can be recorded into the computer either wet, dry
or both (via the effects processor return or the
direct mic input).
■
■ The ADAT optical connection provides 8
channels of 24-bit digital I/O to the digital mixer
(or 4 channels at 96kHz). Any device connected to
the Traveler can be routed to/from the mixer with
no latency. Conversely, any mixer channel can be
routed to any device connected to the Traveler with
no latency.

CHAPTER 11
FireWire SMPTE Console
OVERVIEW
CLOCK/ADDRESS
The Traveler can resolve to SMPTE time code,
without a dedicated synchronizer. It can also serve
as a SMPTE time code generator.
The Clock/Address menu provides the same global
Clock Source setting as in the MOTU FireWire
Audio Console (“Clock Source” on page 40), but it
includes additional information: each setting
shows both the clock and the address (time code or
sample location), separated by a forward slash ( / ).
For example, the word clock setting (Word Clock In
/ Internal) shows the clock source (Word Clock In)
followed by the address (Internal). Notice that only
the SMPTE setting supports SMPTE time code as
the reference for address. The digital clock sources
do not support the Traveler’s on-board SMPTE
time code sync.
The FireWire SMPTE Console software provides a
complete set of tools to resolve to SMPTE, and to
generate SMPTE for striping, regenerating or
slaving other devices to the computer.
The Traveler provides a DSP-driven phase-lock
engine with sophisticated filtering that provides
fast lockup times and sub-frame accuracy.
Any analog input and output on the Traveler can be
used for time code (LTC) input and output,
respectively.

Resolving to SMPTE time code
To resolve the Traveler to SMPTE time code,
choose the SMPTE / SMPTE setting in the Clock/
Address menu. This means that the system will use
SMPTE as the clock (time base) and SMPTE as the
The Generator section
provides settings for striping

address. For further details on the hardware
connections involved, see “Syncing to SMPTE time
code” on page 32.
Resolving to video
To resolve the Traveler to video, you need a
synchronizer such as a MIDI Timepiece AV or a
Digital Timepiece to feed word clock to the
Traveler. In this scenario, choose the Word Clock In
clock source setting in The MOTU FireWire Audio
Console. The Traveler uses word clock for the time
base and your host application resolves to MIDI
Time Code generated from the synchronizer. For
details, see “Syncing to video and/or SMPTE time
code using a synchronizer” on page 33.
FRAME RATE
This setting should be made to match the SMPTE
time code frame rate of the time code that the
system will be receiving. The Traveler can autodetect and switch to the incoming frame rate,
except that it cannot distinguish between 30 fps
and 29.97 fps time code. So if you are working with
either of these rates, make sure you choose the
correct rate from this menu.
READER SECTION
The Reader section (on the left-hand side of the
window in Figure 11-1) provides settings for
synchronizing the Traveler to SMPTE time code.
Status lights
The four status lights (Tach, Clock, Address and
Freewheel) give you feedback as follows.
Tach
The Tach light blinks once per second when the
Traveler has successfully achieved lockup to
SMPTE time code and SMPTE frame locations are
being read.
Clock
The Clock light glows continuously when the
Traveler has successfully achieved lockup to an
external time base, such as SMPTE time code or
word clock.
Address
The Address light glows continuously when the
Traveler has successfully achieved lockup to
SMPTE time code.
Freewheel
The Freewheel light illuminates when the Traveler
is freewheeling address (time code), clock or both.
For details about Freewheeling, see “Freewheel
Address” and “Freewheel clock” below.
SMPTE source
Choose the analog input to which the SMPTE time
code source is connected. This is the input that the
Traveler “listens” to for time code.
Freewheel Address
Freewheeling occurs when there is a glitch or
drop-out in the incoming time code for some
reason. The Traveler can freewheel past the dropout and then resume lockup again as soon as it
receives readable time code. Choose the amount of
time you would like the Traveler to freewheel
before it gives up and stops altogether.
The Traveler cannot freewheel address without
clock. Therefore, the Freewheel Address setting will
always be lower than or equal to the Freewheel
Clock setting, and both menus will update as
needed, depending on what you choose.
Keep in mind that freewheeling causes the system
to keep going for as long as the duration you choose
from this menu, even when you stop time code
intentionally. Therefore, if you are starting and
stopping time code frequently (such as from the
transports of a video deck), shorter freewheel
times are better. On the other hand, if you are
80
FIREWIRE SMPTE CONSOLE
!Traveler Manual/Win Page 81 Monday, November 29, 2004 3:50 PM
doing a one-pass transfer from tape that has bad
time code, longer freewheel times will help you get
past the problems in the time code.
Tach light
The Tach light blinks once per second when the
Traveler is generating SMPTE time code.
The ‘Infinite’ freewheel setting
The Infinite freewheel setting in the Freewheel
Address menu causes the Traveler to freewheel
indefinitely, until it receives readable time code
again. To make it stop, click the Stop Freewheeling
button.
Destination
In the Destination menu, choose the analog output
from which SMPTE time code will be generated.
This is the output that sends time code.
Freewheel clock
Freewheeling occurs when there is glitch or
drop-out in the incoming SMPTE time code for
some reason. The Traveler can freewheel past the
drop-out and then resume lockup again as soon as
it receives a stable, readable clock signal.
Stripe
Click this button to start or stop time code. To set
the start time, click directly on the SMPTE time
code display in the Generator section and type in
the desired start time. Or drag vertically on the
numbers.
Click here to edit
the start time, or
drag vertically on
the numbers.
The Traveler cannot freewheel address without
clock. Therefore, the Freewheel Address setting will
always be lower than or equal to the Freewheel
Clock setting, and both menus will update as
needed, depending on what you choose.
The ‘Infinite’ freewheel setting
The Infinite freewheel setting in the Freewheel
Clock menu causes the Traveler to freewheel
indefinitely, until it receives readable time code
again. To make it stop, click the Stop Freewheeling
button.
Stop Freewheeling
The Stop Freewheeling button stops the system if it
is currently freewheeling.
Figure 11-2: Setting the time code start time.
Regenerate
This option, when enabled, causes the generator to
generate time code whenever the Traveler is
receiving either SMPTE time code or ADAT Sync
(via its ADAT Sync In port).
GENERATOR SECTION
The Generator section (on the right-hand side of
the window in Figure 11-1) provides setting for
generating SMPTE time code.
Level
Turn the level knob to adjust the volume of the
SMPTE time code being generated by the Traveler.
The level knob disappears when the Destination is
set to None.

CHAPTER 12
Performance Tips & Troubleshooting
Things seems like they are working fine, but the
Traveler then just drops off line, and the computer
can’t see it anymore on the FireWire bus.
This is a common symptom when the problem is
that the Traveler is not getting enough power.
Check the power source for the Traveler. Make sure
that the power connection meets the requirements
outlined in “Power options” on page 22.
SMPTE/MTC Sync set to “Trigger and Freewheel”
before recording audio while slaved to external
time code.
Why does the start sound not play through the
Traveler?
The Traveler will only playback audio at a sampling
rate of 44.1, 48, 88.2, 96, 176.4 or 192kHz.
Sound Forge and ‘Smooth Scroll’
If the Smooth Scroll option under the Options
menu is turned on, you may experience clicks and
pops or other anomalies in the audio playback.
This gets worse as you zoom in more to the
waveform while playing. For the best quality
playback, turn this option off.
The computer freezes when it starts up
If the computer is unable to boot up, it may be a
conflict with the WDM Driver. As soon as the
computer boots up, Windows will try and initialize
the WDM Driver. If this fails, your computer will
hang. To determine if the WDM Driver is the
problem, boot up in Safe Mode or remove the
MOTU Audio software with the Add/Remove
Programs Control Panel then restart. Reinstall the
Traveler software and choose only to install the
MOTU FireWire ASIO driver, not the WDM
Driver. Restart again.
Traveler inputs and outputs are not available in
SONAR
Make sure that the inputs and/or outputs that you
want to use are enabled in SONAR.
No input from an ADAT
If you are having trouble recording on your ADAT
from the Traveler, check the Digital input setting.
After power cycling, tape decks often come up
configured to record from their analog inputs. You
won't be able to record from the Traveler to a tape
deck until it is switched to digital input.
‘New hardware detected’ window
If you connect your Traveler before running the
Traveler Software Installer CD, Windows will
prompt you that new hardware has been detected.
Cancel this, and run the Traveler Software Installer,
rather than allowing Windows to locate the drivers.
Clicks and pops under word clock sync
Many problems result from incorrect word
clocking. It is essential that all digital devices in the
system be word locked. Consult chapter 4,
“Installing the Traveler Hardware” (page 19) for
detailed information on how to word clock your
gear. Whenever there is any weird noise or
distortion, suspect incorrect word lock.
Audio in SONAR speeds up or slows down
This could be caused by having incorrect SMPTE/
MTC Sync settings when you record audio into
Sonar. These settings are located in the Advanced
Tab in the Audio Options window, accessed from
Sonar’s Options menu. Make sure that you have the
Clicks and pops under ADAT Sync
Sometimes, the ADAT sync cable seems to be
plugged into the Traveler, and partially works - but
it isn’t really all the way in. This can cause clicks
when slaved to ADAT 9-pin. Make sure the cable is
seated firmly.
83
!Traveler Manual/Win Page 84 Monday, November 29, 2004 3:50 PM
Clicks and pops due to hard drive problems
If you have checked your clock settings sync cable
connections and you are still getting clicks and
pops in your audio, you may have a drive related
problem. Set the Traveler Clock Source to Internal
and try recording just using the analog inputs and
outputs of the Traveler. If you encounter the same
artifacts you may want try using another drive in
your computer. Clicks and pops can also occur
when the drive is severely fragmented, the disk
drivers are outdated, or if you are using a SCSI
accelerator that is not optimally configured for
working with audio.
Connecting or powering gear during operation
It is not recommended that you connect/
disconnect, or power on/off devices connected to
the Traveler while recording or playing back audio.
Doing so may cause a brief glitch in the audio.
Monitoring - how do I monitor inputs?
Please refer to the documentation for the audio
application that you are using. If your application
does not support input monitoring, you will need
to use the Traveler’s hardware-based CueMix DSP
monitoring feature. Please see chapter 9,
“Reducing Monitoring Latency” (page 65).
No optical inputs or outputs are available in host
audio application
Check to make sure you have the desired optical
inputs and/or outputs enabled in the MOTU
FireWire Audio Console.
