"It was made in Soviet Union at well-known Kachkanar (Polivoks) factory. This 2-manual instrument combines mono analog synthesizer and poly analog organ/strings. Synth has double OSC, noise generator, many different types of modulation, excellent analog filters, stereo phaser, ring modulator etc. Organ has several timbres with vibrato and chorus. It’s great instrument for any music styles and sound fx design. Sound is very original, warm and really individual! I think EMS-01 sounds more interesting than well-known Polivoks and many other popular analog synths. By the way, Formanta EMS-01’s retail was 3 times more than Polivoks in USSR!"
