The Polymoog has a 71-note weighted Pratt & Read touch-sensitive keyboard divided into three sections with a volume slider for each. It also has a three-band resonant graphic equalizer section, which can be changed to a low/bandpass/high-pass filter. The Moog-designed 24 dB filter section allows modulation modulated from its own envelopes, low frequency oscillation and sample and hold circuit. Ranks and waveforms of all notes are also adjustable combining waveforms, octaves, tunings, and their own independent LFO rates and amounts. The user can adjust the instrument's sounds, and it offers named "strings", "piano", "organ", "harpsichord", "funk", "clav", "vibes", and "brass". Presets were factory created as physical circuit cards and may be modified for live performance using Var(iation) buttons, triggering a red dot next to the preset number in the display.
