Model 208 (Late version) Wavefolder
P4L "TIMBRE" module replicates the wave folder circuitry of the Model 208 (late version). The wave folder is a function that adds overtones to the input signal by folding the waveform, one of the characteristic sounds of West Coast synthesis.
This P4L version has an additional attenuator/booster on the input to accommodate various levels of input signal to achieve the appropriate fold effect. Sine to Tri converter is also incorporated to add variation to the fold effect.
Uses valuable NOS transistors according to the original circuit.
