Polymoog Synthesizer

Moog Polymoog Synthesizer

Released: 1975

MSRP: $5295US

Synopsis:

A fully polyphonic synth (model 203A), with a dedicated brightness VCF and VCA for each key (i.e. 71 total), but two divided VCOs, a shared programmable VCF, and a bad reputation for being unreliable (and expensive to fix). Lower (two octaves) and Upper (4 octaves) have dedicated waveforms, saw volume, pulse width, and filter (on/off) settings. Architecture Class: Conventional (subtractive).

Ebay Description:

The Moog Polymoog Synthesizer is a 71 key fully polyphonic synthesizer, featuring saw and pulse oscillators, a resonant low pass analog filter, dedicated filter (ADS) and amplifier (ADSR, with shared D/R) envelopes, dedicated oscillator, PWM, and filter LFOs, glide, multiple input and outputs, ribbon controller, 3 low/band/high pass resonators, 8 presets, and CV/gate IO.
