From the description by Ray Wilson :
If you're looking for some new waveforms for your synth you've definitely come to the right place. I have been asked several times to come up with a circuit that takes a basic waveform like a triangle or a sine wave and takes it in a new harmonic rich direction. This circuit takes a triangle or sine wave (or other non-square wave) and allows you to turn it progressively inside out yielding a totally cool sound (peak inversion). Additionally the triangle, sine (or ramp/saw) is converted to what I refer to as a step waveform which has a cool hollow harmonic-rich type of sound. The modified triangle or sine wave output is further enhanced by the addition of a mixer for pulse wave, sub octave square wave and sub-sub octave square wave for very interesting harmonic rich sounds. You'll love the dry sounds you get but when put through a resonant filter your ears will get a real treat. Finally some new waveshapes beyond sine, tri, ramp, saw and square.
Turns a Triangle or Sine Wave Into a Harmonic-Rich Waveform. Provides several waveforms: Inverted Peaks Wave (CV modulation capable) Stepped Wave (CV modulation capable) PWM Rectangle (CV modulation capable) Square Sub-octave of fundamental Square Sub-Sub-octave of fundamental Voltage Controlled Wave Shape Modulation Voltage Controlled Step Wave Modulation
