Polyvox (MiniMoog), Serial Number: 0389383, March 1983, made in USSR

Description: ruskeys

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. 

Engineer: Vladimir Kuzmin, designer: Olympiada Kuzmina, hardware engineer: Yuriy Pheophilov, produced by Urals Vector Company.
