It swings what it syncs… It’s Swynx!
WELCOME
Thank you for choosing the Swynx.
The Swynx is a sync box that converts MIDI clock messages to MIDI
clock, DIN Sync, CR-78 clock, and Analog clocks. In addition, the Swynx
provides the ability to swing the timing of all these clock outputs and
select different time signatures (both with real-time adjustments), and
also acts as a CR-78 pattern programmer. Wow!
After you try it in your setup, you’ll realize just what you’ve been missing.
For instance, many DIN Sync devices do not provide a built-in swing
function. What a shame, since most of these are wonderful sounding
drum machines.
And many MIDI sequencers and drum machines suffer from poor
implementation of swing, preventing changes to be made live, or
providing swing for only 4/4 patterns.
How about the necessity to sync analog sequencers and arpeggiators
with MIDI gear? And now you can swing the timing of those devices as
well.
Support for the fabulous Roland CR-78 has been lacking in the past.
Finding a WS-1 or TS-1 programmer for this drum machine is next to
impossible. The Swynx can replace the need for either of these devices,
allowing your CR-78 play in time with other MIDI devices, and swing its
internal patterns. The ability to add swing alone will breathe new life into
this old friend.
The Swing value is accurate to 0.5% providing much more control than is
typically found in sequencers and drum machines.
The Swynx is all about making the gear you have sound better.
We encourage you to approach the Swynx as a tool for live manipulation
of music timing.
Whatever you do with it… it’s got to be funky!
PRECAUTIONS
Never expose this device to rain or moisture. If liquids are spilled into the
unit, unplug the power supply immediately and let the unit sit in a dry
warm environment until all moisture has evaporated.
Avoid exposing the unit to smoke, dusty, or extreme hot and cold
environments, as these things may cause premature component failure.
Clean the exterior with a soft dry cloth. Never use abrasive cleaners that
may harm the surface and finish of the unit.
Never use AC output power supplies with this unit. Should your power
supply become lost or damaged, replacements can be purchased
directly from Future Retro.
WARRANTY
A 1 year warrant is provided for this product. Please register the product
within 30 days of purchase online at: www.future-retro.com/register.html
for your warrant to be valid.
POWER
A universal power supply is provided with your unit. This power supply
can be used in any country simply by using the correct AC plug
(included) for your country.
This power supply is a 9V DC center-pin positive, outer-pin negative type
supply and should only be replaced with the same type if ever lost.
Never use AC output power supplies to power the Swynx!
Insert the power supply into the wall outlet. Connect the DC output plug
to the power jack located on the back panel of the Swynx.
There is no power switch, this unit will be on any time power is
connected.
MIDI IN
The MIDI IN accepts MIDI clock and note information.
When using the Swynx for clock synchronization, connect the MIDI OUT
of the MIDI device acting as your master clock to the MIDI IN of the
Swynx.
When using the Swynx as a CR-78 programmer, connect the MIDI OUT
of a MIDI keyboard to the MIDI IN of the Swynx.
MIDI OUT
The MIDI OUT sends MIDI clock for syncing external MIDI sequencers
and drum machines.
Connect this MIDI OUT to the MIDI IN of the external device you want to
sync.
DIN SYNC OUT
The DIN SYNC OUT sends DIN Sync clock/start/stop messages in
24ppq format.
Connect this output to the DIN Sync IN of the device you want to sync.
CR-78, ARP/SEQ SWITCH
This switch determines if the phone jack will produce Clock and Write
signals for the CR-78, or Analog Clock and Reset signal for analog
sequencers and arpeggiators.
To make changes to this setting, first stop playback of the master MIDI
clock being sent to the Swynx. Slide the switch to the desired mode.
Playback of the master MIDI clock can then be resumed.
The analog clock will have a 50% duty for each clock pulse.
PHONE JACK
The phone jack is a stereo output. The Tip connection will provide
Analog Clock or CR-78 clock signals. The Ring connection will provide
an Analog Reset signal, or the CR-78 Write signal.
If only the clock signal is needed, a mono cable can be used with this
output.
If your situation requires Clock and the Analog Reset or CR-78 Write
signals, use a “send-return” audio cable to break the stereo signal out
into two separate mono signal connections. These cables are available
from most music stores, and the mono signal connectors are often
labeled as either Tip or Ring for clarity.
LED
The LED on the front panel will blink to indicate activity of the Analog
Clock or CR-78 clock, which ever is selected.
TIME SIGNATURE CONTROL
The Time Signature control provides twelve different time signature
selections, as indicated by the numbers on the inner-ring.
Time signatures can be changed while the unit is syncing, and new time
new signature selections will take affect at the beginning of the next bar.

If the sequencer you are syncing has an adjustable loop point, set the
number of steps to loop for that sequence to even divisions of the Clocks
Per Measure.
Use TABLE 1 to select the ideal number of steps to loop within your
sequencer for each time signature.
Using loop point values other than those listed will produce an evolving
selection of steps. If you are the experimental type, this may be just the
thing you are looking for.
Clock output types can behave slightly different with different time
signatures. We will now discuss these differences.
MIDI
When using time signatures 9/8 through 8/4, set the external MIDI
sequencer to use an internal time signature of 4/4.
When using time signatures 3/4 and 6/4, set the external MIDI sequencer
to use an internal time signature of 3/4.
DIN SYNC
Many DIN Sync devices have pre-scales. Patterns in these DIN Sync
devices should be programmed using the proper pre-scale for the time
signatures in the Swynx.
Time signatures 9/8 through 4/4 work with the 4/4 DIN Sync pre-scales.
Time signature 8/4, works with the 8/4 DIN Sync pre-scale.
Time signature 3/4, works with the 3/4 DIN Sync pre-scale.
Time signature 6/4, works with the 6/4 DIN Sync pre-scale.
Using an improper pre-scale for the time signature the Swynx is
generating, may produce undesirable results.
ANALOG CLOCK
Analog sequencers and arpeggiators generally do not have internal time
signature divisions. They simply play at the rate of the analog clock. If
the sequencer you are controlling has a Reset input, the Swynx Reset
out signal can be used to loop the proper number of notes for each time
signature.
CR-78 CLOCK
Time signatures used in the CR-78 will vary, but in general are mostly
4/4 with a few 3/4. Therefore you will need to experiment and see what
time signature settings in the Swynx provide the best results for
controlling the patterns selected and playing in the CR-78.
For best results with the CR-78, use 4/4 and 3/4 time signature settings
in the Swynx. Time signatures 2/4, 8/4, and 6/4 can also provide usable
results.
In general, irregular time signatures 9/8, 7/8, 6/8 and 5/8 will not
generate pleasing results with the CR-78 due to how it handles clocks.
But you’re free to try them out.
SWING CONTROL
The Swing control allows real-time control of the timing of specific clocks
and how they are delayed to create a more human feel.
The Swing control range is from 50% to 75%. A setting of 50% produces
strictly quantized clock timing, while a setting of 75% produces the
maximum amount of swing effect.
Adjustments made to the Swing value will take affect on the next interval
of notes. This interval varies with different time signatures, see TABLE 2.
For instance, with a 4/4 time signature and a swing interval of 1/8th
notes, changes to the Swing value will take affect every 1/8th note.
Notice there are two selections for the 2/4, 4/4, and 3/4 time signatures.
Each of these provides a different swing interval to produce a different
feel.
NOTE: Swing control has no effect on 9/8 and 7/8 time signatures.

SYNCING
Connect the MIDI OUT of your master MIDI clock device to the MIDI IN
of the Swynx.
Connect the MIDI, DIN SYNC, and Analog/CR-78 clock outputs to the
appropriate MIDI, DIN SYNC, and Analog/CR-78 clock inputs of each
device to be synced.
Make sure MIDI and DIN Sync devices to be synced are properly setup
to receive external clocks.
Since the Swynx does not provide a Start/Stop control for the CR-78, you
need to press the CR-78’s Start/Stop switch to cue up the sync
operation. You will need to do this every time before playback is started.
Start playback of the master MIDI clock device, and all devices syncing
to the Swynx should begin playback.
Before stopping playback of the master MIDI clock, press the CR -78’s
Start/Stop switch. This allows the CR-78 to stop and reset to its first step.
If you fail to press the Start/Stop switch before playback is stopped, the
CR-78 will not play from the beginning of the bar when playback is
started again.
Stop playback of the master MIDI clock, and playback of all devices
syncing to the Swynx will stop.
A FEW NOTES ON SYNCING
It is normal for the first clock generated (when playback starts) to be
shorter in duration than typical for the selected Time Signature and
tempo. This is due to the way the Swynx has to calculate incoming MIDI
clocks to generate the output clock signals.
Changes to the master tempo can in some cases cause timing errors
while syncing. In general slowing the tempo down will not cause
problems. But when increasing the tempo, do so with gradual changes.
Increasing the tempo quickly may cause missed MIDI clocks to occur.
PREPARING THE CR-78 FOR PROGRAMMING
•
Connect the MIDI OUT of a MIDI keyboard to the MIDI IN of the
Swynx.
•
Connect the Ring portion of the Swynx phone jack to the Write IN of
the CR-78.
•
Set the analog output switch on the Swynx to the CR-78 position.
•
Select one of the CR-78’s four user memory locations to write to.
•
Set the CR-78 Programmer switch to the ALL position, and press the
CLEAR key. This clears out the contents of this user memory
location.
•
Connect the Tip portion of the Swynx phone jack to the CR-78’s
Clock IN.
•
Set the CR-78 Programmer switch to the MEMORY position.
•
Press the Start/Stop switch of the CR-78.
•
The CR-78 is now ready to be programmed.
STEP WRITE: PROGRAMMING THE CR-78
•
Use the Instrument Selector of the CR-78 to select an instrument
track to write.
•
Set the note duration to be written into the CR-78 using the Swynx
Time Signature control. Note durations are indicated by the outer
ring of numbers displayed around the Time Signature control.
•
To write a note-on for the current step, play any white key on your
MIDI keyboard. The CR-78 will then advance to the next step.
•
To advance the CR-78 to the next step without writing a note, play
any black key on your MIDI keyboard.
•
Patterns in the CR-78 are all two bars in length. Keep track of what
position you are currently writing to.
•
Once two bars are programmed, you can continue adding notes to
this instrument track, or select another instrument track to write.
•
Repeat these steps until all four tracks have been written.
CHECKING YOUR PATTERNS
•
Press the Start/Stop switch of the CR-78 to stop programming.
•
Set the CR-78 Programmer switch to the PLAY position, remove the
cable going to the CR-78’s clock IN jack, then press Start/Stop to
play the CR-78 and hear the results.
•
If mistakes are made, clear individual instruments by setting the
Programmer switch to MEMORY, select the appropriate instrument,
and press the CLEAR key on the CR-78. To clear all instrument
tracks, set the Programmer switch to ALL, then press the CLEAR
key.
•
If patterns need further editing, make sure playback of the CR-78 is
stopped. Reinsert the cable into the CR-78’s clock IN jack, and press
the Start/Stop switch of the CR-78 before proceeding with step
writing.
TAP WRITE: PROGRAMMING THE CR-78
An alternative method to Step writing is manually tapping the beat into
memory.
For this method, do not connect a cable to the CR-78’s clock IN jack.
Connect a cable from the Swynx Write output, to the CR-78’s Write IN.
•
Select the 1/48 note duration with the Time Signature control of the
Swynx. This allows notes to be written more rapidly.
•
Start playback on the CR-78, and tap the rhythm into memory by
playing white keys on your MIDI keyboard.
•
When using this method, it is helpful to slow down the tempo the
CR-78 is playing at. You might also select a preset like ROCK 1 to
play along with so you have a reference of where down beats exist.
•
If mistakes are made, clear individual instruments by setting the
CR-78 Programmer switch to MEMORY, selecting the appropriate
instrument, and pressing the CLEAR key. To clear all instrument
tracks, set the Programmer switch to ALL, then press the CLEAR
key.
TIPS
•
Using the Tap write method to enter notes into the CR-78 can take
some practice to play notes on the correct beat. This is because the
CR-78 has an internal quantization value of 48 steps per measure.
If you make a mistake, simply erase the track and try again.
•
You can combine Step and Tap writing methods when programming
the CR-78. For instance you may want to Step write a 1/4 note kick
and snare track to lay the foundation. Then switch to the Tap write
mode to lay down a bongo or conga track.
•
The Swynx supports the 24ppq (pulse per quarter note) DIN Sync
clock standard. This standard was popularized by Roland and used
throughout their DIN Sync line of equipment. Some other companies
like Korg adopted a 48 ppq DIN Sync clock standard.
While you can sync the 48ppq DIN Sync devices with the Swynx,
keep in mind that these devices will play back at half tempo, and
Swing values may have little to no effect on their timing.
