Polymoog

Unlimited polyphony at the cost of total sonic control — it plays chords, not characters.

The Polymoog is a 1975 Moog keyboard that gives unlimited polyphony through divide-down oscillator architecture — but sacrifices per-voice synthesis, programmability, and filter control entirely.

Chapters & takeaways4
  1. 1:00
    What kind of synth is it?

    It is a hybrid polyphonic analog synthesizer — not fully analog per voice, not digital, not modular.

  2. 2:30
    How does it make sound?

    It derives all notes from one oscillator via divider circuits — like an organ, not a Prophet-5.

  3. 4:22
    What can’t you do with it?

    No per-voice oscillators. No per-voice filters. No patch memory. No user programming.

  4. 5:32
    What made it special then?

    Its unlimited polyphony was revolutionary in 1975 — and remains its sole technical distinction.

Worth your time?

Yes. Use the whole thing.

The written brief1 min read

What it is and what it was built for

It is a hybrid polyphonic analog synthesizer in keyboard form, built for live chordal textures and ensemble-style pads, not monophonic leads or evolving timbres.

How it works, in terms a player would use

It uses divide-down oscillator technology, like an electronic organ. One master oscillator feeds dividers to generate all notes. There are no per-voice oscillators or filters. You cannot program or save sounds.

What it does better than anything else

It delivers unlimited polyphony — every key pressed sounds, simultaneously, without voice stealing. No other 1975 synth offered that.

What it does badly

It does not allow per-voice synthesis. You cannot shape individual notes with dedicated filters or envelopes. You cannot store patches. Its programmability is non-existent.

What people made with it

Musicians used it for sustained chords, choir-like pads, and string ensemble layers — textures that benefit from massed, unvaried voices.

Who should use it, and who should not

Use it if you want vintage organ-string hybrid textures and do not need editing, patch memory, or per-note control. Do not use it if you expect subtractive synthesis flexibility or modern workflow.

Is it worth your time

It is worth your time only if you need lush, fixed-polyphonic pads and accept zero sound design flexibility. It does not behave like a modern synth — it behaves like a keyboard with built-in string and choir textures.

MemorymoogMoog · 1982The Memorymoog is a 6-voice polyphonic analog synthesizer manufactured by Moog Music from 1982 to 1985. It was the first polyphonic Moog to feature dedicated oscillators and filters for each voice. Each voice has three voltage-controlled oscillators with pulse (variable width), saw, and triangle waveforms. Each voice also has its own 24 dB/Octave Low Pass voltage-controlled filter. Moog Music included a discrete implementation of its famed, patented transistor ladder filter. In Mono mode, the Memorymoog functions as a traditional monophonic synthesizer with 1–18 oscillators selectable in unison. A Chord Memory function and an Arpeggiator are included. Audio frequency modulation using Oscillator 3 can produce FM-like timbres.

Prophet-5Sequential CircuitsThe Prophet-5 is an analog synthesizer manufactured by Sequential Circuits. It was designed by Dave Smith and John Bowen in 1977. It was the first polyphonic synthesizer with fully programmable memory. Before the Prophet-5, synthesizers required users to adjust controls to change sounds, with no guarantee of exactly recreating a sound. Sequential used microprocessors to allow users to recall sounds instantly rather than having to recreate them manually. The Prophet-5 facilitated a move from synthesizers creating unpredictable sounds to producing "a standard package of familiar sounds". Initially, Smith and Bowen developed the Prophet-10, a synthesizer with ten voices of polyphony, meaning it could play up to ten notes simultaneously. Smith and Bowen removed half the electronics, reducing the voices to five and creating the Prophet-5. In 1978, Sequential released the Prophet-5, the first programmable polyphonic synthesizer, which was widely used in the music industry. Whereas previous synthesizers required users to adjust cables and knobs to change sounds, with no guarantee of exactly recreating a sound, the Prophet-5 used microprocessors to store sounds in patch memory.
