PWM parameter Range Description
Ratio 0.250-64.000 in
varying increments
How many times PWM happens in a single cycle.
Hold [SHIFT] to jump by whole numbers.
Depth 0-128 in increments
of 0.1
Controls harmonic range of PWM
Feedback 0-150% Feeds the PWM output back into itself

Dry/Wet 0-100% Mix raw waveform + PWM result; 100% = pure
Mutant
PW-Orig
This is the “vintage” PWM used by many
analog polysynths in the ‘70s and ‘80s: a
waveform is xed at its center and both of
its edges are moved to compress or expand
its width. The PWM source is often an LFO,
though an Envelope or other sources can yield
excellent results.
PW-Sqeez
This form of Pulse Width modulation grabs the
start and end points of the modulation and
then squeezes them to the right. It might help
to think of this as “time-warping” a waveform:
It makes the oscillator go slow at rst and then
go fast, all in the space of a single cycle.
PW-ASM [Warp]
PW-ASM mode divides the selected waveform
into 8 sections that are framed by Warp
points. The values chosen for each Warp point
determine how warped each section of the
waveform can become.
Here’s an example of PW-ASM mode in action.
1. Start with an initialized patch (press
[INIT] twice).
2. Access [OSC 1] and select the sine wave.
3. Access [MUTANT 1] and select PW-ASM
mode.
4. Set Mutant 1 Depth to 128.0 and Dry/
Wet to 100%.
5. Press Control button 7 to access Custom
Edit.
6. Hold a note and turn Control knob 2
slowly.
7. Listen and watch the display as Warp2
changes from 0 to 128 and back.
Note how the waveform is aected only
in one specic area (i.e., Warp point 2).
8. Repeat steps 6 and 7 with one or more
Warp points at various values.
9. Also try dierent settings for Ratio,
Feedback, and Dry/Wet. The sonic
potential is nearly limitless.
PW-ASM mode is actually a form of Frequency
Modulation (FM). It allows you to draw your
own modulator waveform by selecting
dierent values for each of the 8 Warp points.
Construct a slope, a valley, a mound, jagged
peaks, pseudo-random, etc.; your design will
become an FM source (i.e., the modulator).
Each Warp point can be a destination
in the Mod Matrix, so timbral changes
can be as subtle or wild as you like. For
example, use synced LFOs as mod
sources and various Warp points as
destinations.
Harmonic
At its maximum Depth and impact (100% wet)
the Harmonic mutator emphasizes individual
harmonics in a waveform and de-emphasizes
the others. Its eect is heard more obviously
on waveforms rich in harmonics, like a
sawtooth wave, than on a simpler waveform
such as a sine wave.
