Memorymoog

The only Moog with six real voices—and six real points of failure.

The 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.

    Six voices, six filters

    It was Moog’s last polyphonic hardware—and the first to give each voice its own oscillators and filters.

    What’s under the hood

    Three VCOs per voice, variable-pulse waveforms, and a discrete 24 dB/octave ladder filter define its raw, immediate sound.

    Unison power, limited memory

    Mono mode stacks up to 18 oscillators; chord memory and arpeggiator are functional but shallow.

    FM by accident

    Oscillator 3 modulated at audio rate delivers FM-like grit—unusual for an analog subtractive synth.

The written brief1 min read

What it is and what it was built for

The Memorymoog is a 6-voice polyphonic analog synthesizer made by Moog Music from 1982 to 1985. It was built to deliver true polyphonic analog synthesis with Moog’s signature filter and oscillator character—after the divide-down Polymoog failed to satisfy players wanting per-voice control.

How it works, in terms a player would use

Each voice has three VCOs with pulse (variable width), saw, and triangle waveforms. Each voice has its own discrete 24 dB/octave Moog ladder filter. Mono mode stacks 1–18 oscillators across voices for unison leads or bass. Chord Memory holds one chord per key. The arpeggiator runs independently. Oscillator 3 modulates at audio rate for FM-like timbres.

What it does better than anything else

It delivers six independent analog voices with dedicated VCOs and discrete ladder filters—the first and only Moog to do so. Its unison mode gives unmatched analog thickness. Its audio-rate VCO-3 modulation creates gritty, unstable FM-like tones no other Moog achieves.

What it does badly

It lacks full patch memory: only chord positions are stored, not sound parameters. It has no velocity or aftertouch. Its build quality is fragile—many units failed within years. The arpeggiator and chord memory are basic and inflexible.

What people made with it

Artists used it for rich pads, aggressive unison basslines, and evolving FM-like textures—especially in early 1980s synth-pop and film scoring where its instability became a feature.

Who should use it, and who should not

Use it if you want hands-on, per-voice analog polyphony and don’t mind maintenance, limited memory, and no MIDI implementation (original units predate MIDI). Avoid it if you rely on recallable patches, expressive controllers, or daily reliability.

Is it worth your time

Yes—if you need six-voice analog polyphony with true per-voice architecture and unison heft. No—if you need reliability, patch memory beyond chords, or modern workflow integration.

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.
