Normally, when the gain of an input signal exceeds
the headroom of a circuit, the tops and bottoms of the
waveform are clipped o, causing distortion (such as in
the Labyrinth MIXER). A wavefolder, however, folds the
sections of the signal exceeding the floor/ceiling back
in on the signal itself, creating new harmonics in the
process. The VCW FOLD control increases the depth of
folding of the input signal, and the VCW BIAS control
adds a DC bias (either positive or negative), achieving
asymmetrical folding and emphasizing even
or odd harmonics.
VCW FOLD
This sets the amount of wavefolding. It passes a clean signal all the way to the
left with maximum wavefolding all the way to the right.
VCW EG1/CV AMT
This sets the amount that envelope EG1 modulates VCW FOLD. It has bipolar
control, with positive modulation above 12 o’clock and negative modulation
below. EG1/CV AMT acts as an attenuverter for CV input to VCW FOLD
if patched.
