The Polivoks is a vintage portable analog synthesizer designed for performance, studio recording, and sound effects creation. It is a classic Soviet-era instrument known for its raw, aggressive tone and distinctive analog character.

It features a 4-octave full-size keyboard and an intuitive front panel divided into functional sections: modulator, two oscillators, mixer, filter, and amplifier. This layout allows for fast sound shaping and a wide range of sonic possibilities.

The synth includes three internal sound sources: two wide-range oscillators with variable waveforms and a noise generator for non-musical effects such as wind, surf, or mechanical sounds. It also supports external audio input, allowing processing of instruments like guitar, electric piano, or organ.

A resonant filter with adjustable cutoff frequency and resonance enables deep tonal shaping, from sharp leads and basses to experimental textures.
