"Classic Polymoog 203a (The fully programmable Polymoog version) in good working condition. I have owned this Polymoog for over 3 years and it has never given me any trouble. The guy I bought it from said he had it electronically refurbished and I think this is why this Polymoog is reliable. Serial number is well over 3000 which means it is one of the Polymoogs you want. Sounds beautiful and has a real vintage vibe to it which makes it great to sit at and play."

Introducing the Onde Magnétique OM-1 Cassette Synthesizer

Published on Jul 5, 2016 Scott Campbell

http://www.ondemagnetique.com

"The OM-1 Cassette Synthesizer is an analog musical instrument built around the concept that when a continuous tone/note is recorded to tape, its pitch will change as the tape's playback speed is increased or decreased. Individual notes are playable via the 8 buttons (keys), each with a tuning knob directly above it. The volume of the notes can be articulated by using the pressure sensitive volume control - the harder its pressed, the louder the note. A three position switch controls attack/release response of the audio output - Short, Medium, and Long. CV/Gate inputs allow control over the cassette's pitch and volume from a linear (non-quantized) voltage sequencer."
