Notes The Polymoog is the descendant of an ambitious project by Moog Music to create a large ensemble system called the Constellation. It was to include two keyboard synthesizers, the polyphonic Apollo and monophonic Lyra, and the Taurus foot pedalboard synthesizer. Although the Constellation project never made it to production, the Taurus pedalboard was released on its own, while the "Apollo Polyphonic Synthesizer" went on to become the Polymoog. It is also noteworthy that the Apollo/Polymoog project did not directly involve Bob Moog and was instead mostly designed by Dave Luce at Moog Music.

The Polymoog (model 203a) is a fully polyphonic preset-based synthesizer released in 1975. Its eight preset sounds consist of Strings, Piano, Organ, Harpsichord, Funk, Clavi, Vibes and Brass. There is also a Var (Variation) mode that allows any one of the preset sounds to be fully modified into unique and wild analog sounds using all of the available synthesis parameters on board. There’s a genuine Moog ladder filter inside with modulation, keyboard tracking and lots of LFO modulation sources. The Polymoog features a full 71-key, velocity sensitive Pratt & Read weighted keyboard that can be split into three sections, each with independent volume sliders. There is a 3-band EQ, sample-and-hold, pitch controller ribbon and a full set of envelope controls. What you won’t find, however, is patch memory or MIDI control.
