polivoks vcf

price : $200.00


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 self-oscillating with a dirty pulse.



specifications:
made in cooperation with vladimir kuzmin
manual and voltage-controlled cutoff frequency
manual control of resonance
bipolar cv input multiplier
2-input signal mixer (easily overdrives filter)
low- and bandpass outputs
panel size: 10hp
original Soviet integrated circuits - no capacitors used in the design!

the user manual is available online here. Some demonstration sounds can be downloaded below:
1. sound clip by rewire! this 1:50 mp3 demo has just two sawtooth waves going into the filter with plenty of modulation of the vcf. the last patch in the demo is the bandpass output being used as a cv source to the vcf.

sounds from the manufacturer. the following clips feature two oscillators in unison.:
1. lowpass sweeps, increasing resonance
2. audio-rate fm, sinusoidal modulator
3. bandpass output tests
4. inverted bandpass mixer feedback trick
