"Polivoks had been produced since 1982 by Formanta electronic factory (one of the biggest at the time); it was sold exclusively in the USSR. Polivoks has its own particular electronic parts, reliable keyboard (49 notes F to E) made in magnetically controlled contacts; synthesis modules consist of independent boards, which is convenient for maintenance. The synthesizer has 2-voices polyphony; each oscillator works with a keyboard note independently; two types of filters - bandpass/lowpass and external input for cutoff control. In addition, Polivoks is housed in an original body of uncommon design with handy controls. Being closed with a cover, the synthesizer turns into a strong aluminum case.
Polivoks is the portable electronic musical synthesizer which is designed for playing different musical compositions of any genre. It is also intended for creating some musical effects in cinema and play scoring, in studio.
There are 4 octaves on the keyboard. The inclined desk is divided into the following functional sections: Modulator, Generator #1, Generator #2, Mixer and Amplifier. They give one a possibility to synthesize a broad spectrum of sounds and to change sounding at any time.
There are 3 internal audible signal sources in the instrument: to broad-ranged of the Generators with changed form of oscillations and a noise generator for creating a non-musical sounds such as wind, surf, whine, etc. Possibility to connect an external audible signal sources to the synthesizer is provided for (e.g. guitars, electropianos and electroorgans). Sounds of different external sources are combined separatly in the mixer in any ratio. There is a filter in the synthesizer with cutoff frequency control and resonance to change colour of timbre of audilble signal over a wide range.
Polivoks is the most popular vintage Russian synthesizer all over the world. It has inimitable peculiar sound and very powerful aggressive filters outperforming the famous Minimoog! A fat, lush and very analogue sound is achieved through instability and thanks to unique architecture of the Soviet-era components; in addition, highly reliable military technologies were applied in the process of production. The synthesizer may be used for hard electronic music, or for soft ambient/old school projects and for modelling various effects as well.
