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. Press the Page Down arrow to access page 2.
2. Press Control button 4 to access Custom
Edit.
3. Hold the low C key and turn Control knob 2
slowly.
4. 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).
5. Press the Page Down arrow to access Warp
points 5-8.
6. Repeat steps 7 and 8 with one or more
Warp points at various values.
7. 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.
