The mod-amount knob affects the incoming signal in an attenuated and amplified, linear fashion. A set-
ting of 127 (maximum) amplifies the incoming signal to twice its original level, a setting of 64 leaves the
incoming signal unaffected and a setting of 32 attenuates the incoming signal by a factor of 0.5 (leaving
half of the level of the incoming signal to modulate). A setting of 0 shuts off the modulation completely.
The frequency mod-input on the various filters are the sole examples of Type III attenuation.

Let us use the pulse width on the OscillatorA module as an example in two scenarios:
