AS3320, wavefolded resonance, voltage controlled low pass filter.
This is the functional prototype of our voltage controlled, 4 pole, low pass filter, with the AS3320 at its core. It has 1 input, 1 output, 2 frequency modulation controls and 1 resonance modulation control. We added a wavefolder and diode distortion to the resonance feedback loop, with a switch to select between either just wavefolding, or both.
