 Ps301 Diode Wavefolder is a dynamic waveform processor module, that changes the color and the overtones of a sound, while keeping the same base note. The design is originally Jürgen Haible's take on "Serge Wave Multiplier, middle section". Yves Usson of YuSynth added an exponential VCA to the design, making voltage control possible, and we modified the circuit further to fit our design requirements.  Ps301 Diode Wavefolder is a dynamic waveform processor module, that changes the color and the overtones of a sound, while keeping the same base note.

 The module takes in a 10Vpp sine, triangle or saw wave and folds this waveform back into itself up to 7 times at the crossover point of the wave.The effect sounds a kind of mix of frequency modulation and mid resonance filtering. The module takes in a 10Vpp sine, triangle or saw wave and folds this waveform back into itself up to 7 times at the crossover point of the wave.The effect sounds a kind of mix of frequency modulation and mid resonance filtering.

 The Controls Include "CV attenuation", "Fold Range" (which can also be contolled with 0-5v control voltage) and "Fold Amount" which changes the amount of folds. Inputs and outputs conform to eurorack standards of 10Vpp, and it runs on eurorack  +-12v power supply, and even with +15v power supply from Frack Rack or MOTM synthesizer systems. The Controls Include "CV attenuation", "Fold Range" (which can also be contolled with 0-5v control voltage) and "Fold Amount" which changes the amount of folds.
