The Polivoks Filter is famous for its’ crazy resonance sweeps and deep low-end sound which makes it ideal for acid-style basslines. We believe this is one of most is one of most authentic sounding Polivoks VCF emulations available. The original Russian ICs K140UD12 are used in the audio circuit and there are several design updates which adapt the Polivoks VCF II for contemporary modular synth demands.

Updates include:

  • Independently buffered inputs
  • Extended Cutoff knob range
  • Eliminated clicks when switching filter modes
  • Output stage added to eliminate signal inversion


Switchable BP/LP modes
Inputs/outputs protected against over-voltage
Protection on reversed power supply
Skiff friendly design
Unique Polivoks character!
