GiO by APOGEE – User’s Guide
Working With GiO
In this section you’ll find answers to questions that might arise while
using GiO as part of a Mac-based recording system.
How do I set a recording level?
Once your instrument is connected, your audio software is
configured and you’ve created a new recording track, just how do
you set the input gain for a proper recording level in your audio
software? There’s no simple answer, but with a few guidelines and a
bit of experience, you can master setting a proper level.
How do I set my software’s I/O buffer?
The I/O Buffer setting found in most audio software is one of the
most crucial, but often ignored, settings in a Mac-based recording
system.
When choosing a buffer setting, a compromise between the latency
through the application and the amount of computer processor power
accessible to the application must be made.
Latency
Ideally, the input gain should be set so that when the input signal
is at its loudest, the level in audio software is just below maximum
without lighting the Over indicator.
In reality, it’s unlikely that you’ll be able to guess just the right gain
setting to accomplish this - when your gain is too low, the signal
never gets close to maximum and when your gain is too high, a
digital Over may occur. Now, with a 24-bit system (such as GiO), the
noise floor is so low that there’s no real penalty for undershooting
the gain setting and recording at a lower level. There IS a penalty
for overshooting the gain setting - a digital Over that results in
significantly increased distortion. Thus, it’s better to work with a
recording level that’s a bit too low than a level that’s a bit too high.
Just how much to undershoot the gain setting is determined by the
nature of the sound being recorded. As a general rule, instruments
such as bass and organ have a more consistent level than
percussive instruments, such as a tambourine, and may be recorded
at a higher level. Also, the performer’s skill and playing style can
dictate more or less caution when setting levels. As you gain
experience, you’ll be able to more accurately set a good recording
level while avoiding digital overs.
Latency - the slight delay between the moment you play a note and hear it in your
headphones after conversion and processing.
A lower buffer setting results in lower latency but less available
processing power. If the application can’t access enough processor
power, processor overruns may occur, resulting in audible clicks and
pops or error messages that interrupt playback and recording.
A higher buffer setting, on the other hand, results in greater amount
of accessible processor power (i.e. less chance of overruns) but
increases the latency. Determining the best setting requires some
trial-and-error in order to find the best compromise.

GiO by APOGEE – User’s Guide
I/O buffer continued
Keep in mind that as tracks and plug-ins are added to a software
session, processor requirements increase. Thus, the buffer setting
that works during the early stages of a session might result in
processor overruns during later stages.
The best strategy is to set the buffer to a lower setting during
recording and accept certain limitations on plug-in usage, and then
raise the buffer during mixing to utilize the computer’s full processor
power when latency isn’t an issue.
With the processing power of today’s Macs, you may find that
adjustment of the buffer isn’t necessary, and you can leave it at
a setting for low latency and still access a sufficient amount of
processing power when adding tracks and plug-ins. If you do
encounter clicks, pops or software errors, don’t hesitate to
experiment with the buffer setting.
Please consult the section on Working with GarageBand, Logic and
Mainstage to determine how to se the I/O buffer setting is found in
your audio application.
Can I record my session on the startup hard
drive?
It’s an accepted “best practice” of most audio software providers
that audio files should be recorded on a hard drive other than the
Mac’s Startup drive (i.e. the drive on which the operating system is
installed). You can probably get away with recording a few tracks to
your computer’s Startup disk, but for the best performance of your
GiO recording system, record onto a separate ATA/IDE, SATA, or
FireWire drive whose spindle speed is at least 7200 RPM.
How do I set the input control of my powered
speakers?
Most powered speakers offer an input volume control, often labelled
as input sensitivity. Rather than describe an overly complicated
method for setting this control, the easiest way to determine the right
setting is to note where you generally set GiO’s output level. If you
find yourself rarely turning the output past a very low output level
(say, -35 dB), decrease the input sensitivity on the speaker. If, on
the other hand, you find yourself setting GiO for full output and the
What sample rate should I record at?
speakers aren’t loud enough, increase the input sensitivity. Ideally,
GiO offers a choice of two sample rates, 44.1kHz or 48kHz. So,
what’s the best sample rate to record your project at? It’s a good idea
to avoid unnecessary sample rate conversion stages, so the answer
is determined by the sample rate of media on which you plan to
distribute your recording. If the final distribution media is CD, record
at 44.1kHz. If the media is video or TV, most often 48 kHz is the best
choice. If you’re part of a larger production chain, and aren’t sure,
ask the person who’s responsible for assembling the final product they’ll undoubtedly appreciate the forethought.
GiO’s output should be at 0 dB when you’re listening at your absolute
20
maximum desired volume.

Using GiO Config
During the installation of GiO software and drivers, GiOConfig is
installed in your Mac’s Applications folder. This utility app offers the
ability to optimize the response of your expression pedal with GiO
as well as quickly determine the versions of software, firmware and
drivers installed.
For the best pedal response, it’s necessary to match the
characteristic of GiO’s expression pedal input to that of your
expression pedal. This is done with the following steps:
• Open GiOConfig (installed in your Mac’s Applications folder).
• In GiOConfig, set the Expression pedal curve to Yamaha or Roland, based on the brand of your pedal.
• If you don’t know which setting to choose, rock your expression pedal between its lowest and highest positions and
choose the setting that offers the smoothest volume envelope as
displayed in the Value progress bar.

GiO by APOGEE – User’s Guide
FAQs
Question - What is GiO?
Answer - GiO is the best way for guitarists to work with Logic Studio
and GarageBand. With GiO, you can connect your instrument,
headphones and speakers to your Mac, and control Logic Pro,
Mainstage or GarageBand hands-free.
Question - Can I still use GiO’s footswitches (Transport, Stompbox
and Previous/Next) while using another Apogee interface (such as
Apogee’s ONE) for audio input and output?
Answer - Yes you can. Simply connect both devices, and choose
ONE as your audio input/output device. GiO’s footswitch functions
will automatically be recognized, regardless of the audio input/output
setting.
Question - Can I use GiO with other applications besides Logic
Studio or GarageBand?
Answer - Playback from any audio application such as iTunes or
DVD Player has greater clarity and dynamic range through GiO’s
output. GiO’s complete functionality, including footswitch control and
illuminated user feedback, is only available with Logic Studio and
GarageBand.
Question - What expression pedals are compatible with GiO?
Answer - First, the expression pedal’s 1/4” connector must be a
3-conductor TRS (tip-ring-sleeve) type. Pedals with a 2-conductor TS
(tip-sleeve) are usually meant for analog volume control, and won’t
work properly. Even amongst 3-conductor expression pedals, there
are two commonly used connection standards. Through the utility
app GiOConfig, GiO supports both standards. Please see page 21
for details.
Question - Yeah, thanks for the expression pedal dissertation, but
which pedals have you tested?
Answer - Apogee has tested the Yamaha FC-7 and the Roland
EV-5. We’ll post additional supported expression pedals on our
website:
http://support.apogeedigital.com
Question - None of GiO’s lights are illuminated - is my GiO powered
on?
Answer - Under certain circumstances of normal operation, none of
GiO’s lights are illuminated. In order for GiO’s Stompbox Indicators
to light, the track onto which stompboxes have been inserted must
be selected. If you’ve selected a track with no stompboxes, the
Stompbox Indicators go out.

Troubleshooting
Symptom - There’s no signal at GiO’s output.
Solution • Verify that the System Preferences Sound windows are
configured as described on page 17.
• If there’s no output after checking the items above, open Audio
MIDI Setup, set Properties For to GiO, and toggle the sample
rate (labelled as Format) from one setting to the other and back.
Symptom - The input connected to GiO isn’t getting to my audio
application
Solution - Check that the audio software has been configured to use
GiO for audio inputs and outputs, as described on pages 10-18.
Symptom - When recording, the input is delayed in my headphones
Solution - Decrease the I/O buffer size in your audio application.
See page 21 for more information about setting the I/O buffer.
Symptom - I hear clicks and pops when recording or playing back
from my DAW.
Solution - Problems with clicks and pops usually indicates that the
I/O buffer in your DAW (audio application) is set too low. Please see
page 19-20 for more information about setting the I/O buffer.
Symptom - When recording in GarageBand, I can see an input
signal but I can’t hear it.
Solution - To hear the input signal of a record-enabled track,
Monitoring must be set to On. Double-click a Real Instrument or
Electric Guitar track header to open the Track Info pane, and verify
the Monitoring setting at the bottom of the pane. On an Electric
Guitar track, highlight the guitar amp and click Edit to reveal the
Monitoring menu.
23
Symptom - When connecting speakers to GiO, there is hum and/or
buzz at the output.
Solution - In most cases, a steady hum or buzz at the output is
caused by grounding issues between GiO and the connected
equipment. Because bus-powered USB interfaces are grounded
through the USB and audio connections, and not through a
3-prong grounded AC connection, the situation may arise where
the grounding configuration of the connected equipment must be
modified. Check that the computer is grounded with a 3-prong AC
connection.
Some experimentation may be required to find the grounding
configuration that results in the lowest noise. It may be useful
to disconnect all equipment except GiO, the Mac and a pair of
headphones, and then connect additional equipment one piece
at a time.
Symptom - GiO doesn’t appear in OS X System Preferences
Solution • Verify that OS X 10.5.8 or later is installed.
• If so, choose About This Mac, then click More Info... to open
System Profiler. In the Contents column, open the Hardware
disclosure triangle and click USB.
• Verify that GiO appears in the USB Device Tree pane.
• If GiO does not appear, try another USB cable or port.
Symptom - Neither the Transport nor Stompbox switches operate
with GarageBand or Logic Studio.
Solution • Ensure that GiO software and MIDI drivers have been installed
• Verify that the correct version of GarageBand (version 5.1) or
Logic Studio (9) is installed.
