A "classic" wavefolder for the AE system
The module is based on a design used also by Ken Stone for his CGS system; the original circuit dates back to a publication from 1973.
Basically, the WAVEFOLDER clips and folds the incoming waveform; usually, waveforms with little overtones (like triangle or sinewaves) are used as input. In general, by the clipping and folding, the signal enriches the input signal with more overtones.
