EVERYTHING SYNTH
"Up for auction is very rare soviet analog polyphonic synthesizer - SOLARIS (Estradin-314). It was manufacture on the same "Estradin" military radio plant in Zhitomir city where was produced power moog-type synths Altair-231, Estradin-230 in eighties. SOLARIS uses organ style drawbars to create the basic tone, and has a analog filtering as well. Inside it has 12 voice boards that correspond to each key in an octave, and then uses a divide down system to get to the other octaves. Because of this the sound of the oscillators are really thick and meaty. The filter is really extreme and sounds fantastic, as well the envelope is really punchy, so you get great synth stabs, sweeps and percussive organy sounds. If you use the envelope and filter sections carefully you can get great moogy leads out of it, warm organ sounds, flying ambient textures, in the high resisters it can sound like a string machine, or even a theremin if you crank the resonance. It has tons of character and can sounds really unique! 

"It has been recently (July) fully overhauled by James Walker of Synth Repair Services. It has had all of the input and output sockets replaced with new SwitchCraft sockets. The high level output, which is usually on a phono socket, has been switched over so now the high output is on 1/4" standard jack. It has had a Filter CV input socket fitted to allow CV control of the Low Pass filter, leaving the pedal input free to Osc 2 pitch etc.
