The Harvestman is proud to present the first widely available modular release of the Polivoks filter circuit. The filter is made via a collaboration with the synth's original designer, Vladimir Kuzmin, and Shawn Cleary of Analogue Haven. The filter circuit is identical to the original design and uses the exact same schematic as the Polivoks synthesizer as well as new old stock Soviet integrated circuits (KR140UD1208 and KR140UD608, not Western "equivalents"). A signal mixer and bipolar CV multiplier were added in order to use the filter within the modular realm but no other additions are present. This helps to preserve the unique and unstable sound character without compromising signal flow authenticity.
First sold in the USSR in 1982, the Polivoks was the first voltage-controlled Soviet synthesizer. Boasting an impressive set of features comparable to Western designs, the synthesizer was noted for its extremely aggressive sound, particularly within the filter. Easy to overload, unstable at high Q values, and prone to self-oscillation.
