A few words about vinthage Soviet synthesizers

alisa soviet synth

Hi dear norCtrack users. Today I decided to talk a bit about the old Soviet synthesizers. Which are still relevant for modern music, especially for electronic music.

Create synthesizers in the Soviet Union, as well as all Musical Products, in my opinion, it was something minor. Large radio factory produces serious products, household appliances, electronic devices, and in parallel, the task of experimental development and release of musical instruments - synthesizers, organs, guitars and so on. Many electronic military factories also engaged in the manufacture of musical instruments (for example, the plant "formant"). Until now, the name of the "ELECTRONIKA" includes a whole range of businesses in different cities that make these organs and synthesizers. Almost every city could produce any radiopredpriyatie some serial or experimental product. And still there are instruments, with unidentified factory marks.

Talk about serious domestic purposes and development of some synthesizers and other electrical equipment I especially do not want to, because in most cases the quality of these devices was not the most pleasurable.

But, on the other hand, engineers, developers have worked in such conditions that put in their place Western counterparts - they are unlikely to have done anything at all!

As for analog synthesizers is domestic production, it has long been recognized that they have a bold, powerful and punchy sound than their foreign counterparts.

And the reason is in the Soviet parts in their unpredictability, discreteness and so on. Talking about the number of different brands of Soviet synthesizers, each time surprising their diversity!

Large plants electromusical smoothly supplied its products to the country. For example, the number of serial production of one of the leaders was the same synthesizer "Polivoks" programming produced by units which reached 20-25 thousand RUB a year. And how many experimental samples! Leaders also sintezatorostroeniya 70-80 years were plants "formant" (Sverdlovsk), "Lel" (Moscow), "Estradin" (Zhytomyr), "Youth" (Moore) and, of course, "Electronics". Almost all of these plants continue their work at the moment.

Each home has its own unique synthesizer features. General synthesis scheme, probably the same everywhere - the oscillator, filter, amplifier, modulation. But it is the detailed design, circuit design, design was unique component of most models.

Many tools have been implemented Soviet boldest ideas developers. The same "Polivoks" has a resonance filter that does not contain a single capacitor.

 Synthesizer "Altair-231" has many individual features, although it is called "Russian Minimoog."

One small generator monophonic synthesizer "Rhythm-2" has such a tight sound that will always betray and trehgeneratorny tool! Thanks to some fortunate combination of the main generator and subgeneratora this model has become very popular among many contemporary musicians.

"Aelita" - no synthesizer in the world has a similar sound (powerful features unison). Of bodies, I would note such models as "Lel-22" (an unusual phase vibrato). Deserves special attention "TOM-1501" - analog synthesizer with orchestral effects (chorus), "Formanta EMC-01" - powerful dvuhmanualny organ synthesizer.

Altair Estradin - 231

Altair-231 Monophonic synthesizer Altair-231 (factory Estradin Zhytomyr) is designed to reproduce the sounds of different nature - from the imitation of natural sounds of instruments to produce complex synthesized electronic sounds, effects, percussion sounds etc. The synthesizer has a 4-octave keyboard, pitch wheel control, parameter controls on the front panel, access to telephones, pedal input. Consists of four main blocks of synthesizing sound - Generators, Mixer, Filter, Circuit. The synthesis is based on the portion 3 of the master oscillator, each with independent parameters registers, the waveform of the modulation frequency. There is a generator of white and pink noise. Low-pass filter with the main parameters allows tracking of the keyboard. Synthesizer includes portamento function with adjustable speed. To configure the system tool is the inclusion tone 440Hz. Line input is provided for connecting an external audio source via Altair-231. Inputs and outputs are 1/4 jacks.

Electronic music synthesizer "Aelita" (Murom plant RIP)

AelitaThree-part electronic synthesizer keyboard "Aelita" - a modern musical instrument. Musical works, performances on "Aelita" may sound differently, if the contractor uses a variety of sound effects: three-part unison timbre glissando, frequency vibrato, timbre tremolo, decay, attack, Strings (string group). You can change the character of the sound directly at runtime, as well as the tone: just turn the handle or touch the control buttons. In the performance of a musical work to "Aelita", you can record on a tape recorder, listen to "game over artist" headphones. The tool can also be used as a musician.

Formants EMC - 01

EMC - 01Combined Musical instrument "formants EMC - 01" combines two tools: polyphonic and monophonic synthesizer organ. Designed to perform any genre of music, as well as to produce various sound effects when dubbing films, performances, recording in the studio. The organ has a keyboard volume five octaves, six fixed sound timbres, frequency vibrato with adjustable delay vibrato adjustment damping stereofayzer (is a common part for organ and synthesizer). The delay vibrato each subsequent time starts only after the release earlier keystrokes. When playing "legato" vibrato delay circuit does not start.

The synthesizer has:

keyboard - 3 octaves ; modulator that modulates the voltage which is applied to a frequency modulator (FM) , latitudinal modulator (CMM) , filter, amplitude modulator ( power ); Generator Generator 1 2 - wideband oscillators with different waveforms ; mixer for summing signals from oscillator 1 , oscillator 2 , a noise generator , an external source, the ring - modulator ; filter for dynamic and static changes in the spectrum of the total signal output from the mixer ; amplifier to make the sound characteristics peculiar to different envelope signal; Visual separation of the Digital Keyboard to the above components, their mutual arrangement facilitates orientation in the recruitment of a tone.

In addition, the synthesizer is capable of controlling other same synthesizer. To do this via a connecting cable, soldered according to the wiring diagram connectors control input and control output (Annex 3), connect the control input to the control synthesizer control output connector managed and controlled synthesizer synthesizer press "КОНТР". In this control panel is disconnected from the synthesizer managed your keyboard connects to the keyboard and synthesizer control, ie one musician have at our disposal - two identical control panel with a single keyboard, therefore, two fully parallel synthesis channel that will expand your chances of making the sounds many times.

The instrument provides the ability to connect stereo headphones, and the regulation of the volume pedal tool from maximum to zero, all outputs instrument, the signal does not change on the phones, which allows pre-control tone telephones through before feeding the signal to the power amplifiers. When you turn on the channel PHASER synthesizer or organ on the nests STEREO A and STEREO P can get a stereo signal. When disconnecting PHASER in both channels will be delivered to MONO.
