The MemoryMoog is an analog subtractive 61-key polyphonic synthesizer that was released in 1982 and produced until 1985. It has 6 voices of polyphony and 3 oscillators per voice. Each of these oscillators can be set to a pulse, sine, or saw waveform.
It has 100 voices of patch memory, a CV/Gate connection, one independent LFO, an ADSR envelope, and a 24 dB/octave low-pass filter. It can also be used in unison mode for an 18-oscillator monophonic lead.
The MemoryMoog made use of Curtis CEM 3340 chips instead of Moog-designed circuits for its oscillators. Some users criticize the sound quality of the instrument due to this, and the unit is prone to experience missing or stuck voices. It also used CEM3340 chips for its VCOs and CEM3360 chips for its VCAs.
The MemoryMoog is known to have been used by 808 State, Air, INXS, Jean-Michel Jarre, Labradford, Rick Wakeman, The Crystal Method, and The Orb.
