A new filter from Erica Synths based on the Polivoks filter. It has unrivalled control with a cut off slope control and also a resonance response control. So your cut off can have a flat curve or a more steep and aggressive reduction of sound above (above in low pass, around both sides in band pass) the cut off point. With the resonance response curve you go from a flat resonance response to Polivoks. There’s also resonance CV, cut off CV and a secondary CV with attenuverter and crossfader to select whether it affects resonance or cut off or both as you fade around the knob.
