Example Patch: Sequencing the STS
The STS works well with a standard
CV/Gate sequencer. A typical patch is
shown on the left.
The Trigger or Gate output of the
Sequencer is patched to the
Play
input of the STS. This makes the
sample fire on each sequencer step.
Some sequencers have gate repeat
effects, which will make the STS fire a
sample multiple times per step.
The CV output of the sequencer is
patched to any of the CV inputs on the
STS. If you want to use the sequencer
to control pitch (playing a sample at
various pitches), patch into the
1V/OCT
jack.
If you want a “multi-timbral” effect,
patch the CV output into the
Sample CV
jack on the STS. Each step of the
sequencer can trigger a different
sample to play.
If you have a sequencer with 2 or more
CV outputs, you can even sequence
both pitch and sample selection at once!
Multi-voice, multi-timbral
Since the STS has two channels, you can use a sequencer with two trigger/gate channels to drive
both STS channels with different rhythmic patterns. In Stereo Mode (see p.8) both stereo samples will
be mixed together. Each side of the STS has its own CV jacks, so you can treat each side of the STS
as an independent instrument, but both draw from the same collection of samples.
You also can select “slices” of a long sample by running the Sequencer into the
Start Pos CV
jack.
Each step of the sequencer can thus play a different slice of the original sample.
STS as the clock source: End Out->Clock In
One variation of this patch is to use the STS itself to clock for the sequencer by patching the
End Out
to the Sequencer’s clock input. Make sure to set the sequencer to run on external clock.
To start the patch, hit
PLAY
on the STS once. The
End Out
will fire, thus clocking the sequencer, which
starts a sample on the STS, which fires an
End Out
when it finishes, which advances the sequencer,
etc… The
Length
control on the STS will control the tempo, which will vary with each step if the
samples are of different lengths. Try this patch with the Sequencer CV out into the STS
Sample CV
.
Note: if the patch seems to run for a moment and then stop, the gate pulse width on the sequencer is
probably preventing it from firing new steps. Either reduce PW to triggers or hold
PLAY
on the STS for
half a second to loop the STS channel.
Clock Divided Reverse
Try splitting/mult’ing
End Out
and running it to
Reverse
. Or patch
End Out
into a clock divider and
use the divisions to reverse playback every N steps! If you only have one side of the STS patched so
far, patch other clock divider outputs into the
Play
on the other side.
