WAVEFOLD MAKESHIFT VCA

Sending a negative voltage into the wavefolder on either VCO results in silence. This feature can be
used as a VCA. Slightly offsetting any envelope with a negative voltage and using this envelope to
modulate the wavefolder is all you need to do to achieve this. Using the same envelope to modulate
the LOW PASS FILTER creates a classic subtractive synthesis voice or a low pass gate emulation.

Alternatively you can use the internally normalized modulation, an external LFO or a VCO to create
AM sounds by using them to modulate the wavefolder. As the modulation goes into its negative range
the wavefolder will temporarily create silence.

Amplitude modulation greatly resembles ring modulation but on top of the sidebands the pitch of the
carrier is also present at the output. This is the main difference between AM and RM.

PULSE WIDTH ANIMATION

Syncing VCO1 to VCO2 (sync switch
to the left) while modulating the
frequency on VCO1 can result in
some PWM-style sounds coming
from the SQUARE output.

Keep in mind that the SQUARE and
SINE

output

on

VCO1

are

not

affected by the low pass filter, the
wavefolder, the phase modulation
nor the shape parameter.

This also works for VCO2.

FILTER FEEDBACK

Self-patching

the

MAIN

OUT

of

VCO1

back

into

the

LPF

input

(through a VCA) can produce some
interesting octave switching effects
when VCO1 is slaved to VCO2 (sync
switch to the left).

Using different outputs from VCO1
to patch back into the LPF leads to
interesting sounds as well.

This also works for VCO2.
