Polivoks

images via this auction
"The Polivoks is the most popular vintage Russian synth made in the early 80's - it was among the first synthesizers produced in the USSR. It had 2 oscillators with pulse or triangle waves, and 1 noise generator, the levels of which were controlled via the internal mixer. You could also connect an external input (guitar, electric piano etc) for mangling with the Polivoks' switchable high/low pass filter and LFO.

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.
