Erica Synths DIY – VCF (Polivoks inspired) PCB and Panel Set

Availability: In stock

This module is 30mm deep, skiff friendly, has solid mechanical construction and doesn’t require wiring. Polivoks VCF is famous for its crazy resonance sweeps and deep, bassy sound which makes it ideal for acid basslines. We believe, this is one of most is one of most authentic sounding famous Russian synth Polivoks VCF emulations available. The original Russian ICs K140UD12 are used in the sound circuit. Several updates have been done to adapt the VCF for contemporary modular synth demands. Independently buffered inputs, extended Cutoff knob range, eliminated clicks, when switching filter modes, and output stage added to eliminate signal inversion.

Uses the 140YD1201С, available from Infinite Machinery.
