Moog's first significant foray into polyphony, as oft-maligned as it is admired, still sought after.

Largely designed by Dave Luce, a Moog Music employee, the Polymoog is a 71-note, fully polyphonic (divide-down) synthesiser, and was produced in two distinctly different models - the 203a and the 208a. The 203a allowed each of the 8 presets to be fully edited and is identifiable by its front panel which is well-stocked with controls. The Polymoog Keyboard (the 208a pictured here) increases the number of presets to 14 but reduces the amount of editing available. Although potentially limited, it was no less popular (as Gary Numan's most famous track will attest to!)
