In 1980 the management of Vector enterprise had come to a decision about including of the synthesizer theme in the plan of researches. The first point of it was the developement of the analogue synthesizer. It was planning to begin serial manufacturing in 1982. The leader of this work was Vladimir Kuzmin, and the designer was his wife Olimpiada Kuzmina. Some skilled engineers were included in this group: Igor Fedosejev, Yuri Feofilov. All researches were made for only one year, and preparation for serial manufacturing took one more year. In this synth there are many features that differs it from the other synths. Firstly, it has perfectly original electronics. Keyboard, as in all other musical instruments of this enterprise, incorporates gercons, magnetically controlled germetic contacts, which makes this keyboard absolutely reliable and lasting. Synthesizer is true two-voice: each VCO is assigned to its key (with only one pair of contacts per key). VCF doesn't have any capacitor at all and use only two op amps. Two envelope generators have great function of self-oscillation with the period of time equal to summ of attack and decay times. This converts this generators into two extra sources of various waveforms and periods for controlling cutoff frequency of VCF and VCA. Secondly, synthesizer is true modular. This means that all units have there own PCB, they can be independently changed or upgraded. Thirdly, synthesizer has very inusual design and graphics. It has image of something military, solid and reliable as a tank. Graphic elements are seperate thin plastic panels. This brings very stylish and unusual appearence and makes it easy to make any changes in graphics.

This is one of the variants of the project. Notice, that oscillators are placed in the right hand. Further it was defined as unconvenient.

For serial manufacturing the Polivoks was given to the daughter enterprise Formanta were it was manufactured till 1990. In the very success years the output was 20-25 thousands of synths. They were sold only in the USSR. The prise was 600 roubles (near $1000). During all the years of manufacturing electronics and construction were constantly improved. That's why the schemes of the early years differ from those of the last years. The date of manufacturing of the certain synth is simple to find on the rear panel near fuse; it manually ingraved. It consists of two-digit number of the month, two-digit number of the year and tree-digit serial number. When buying used synth you must prefer that one of later years with more perfect scheme.
