Product Description

This is a monster of a synth - like six Minimoogs in one with separate filters for each voice, VCO sync, sample and hold... The unison mode can stack up to 18 oscillators for thunderous monophonic bass and lead sounds. Our engineer Huw's favourite synth also. More info from the net below.

The previous owner had maintained this synth very well - all necessary internal upgrades and service work had been carried out to a high standard and the synth auto-tunes every time on start up. We have recapped the power supply and given it a thorough check over and it is working extremely well.

There are a few dings and marks to the wooden parts and a couple of dents/bumps to the aluminium case - at some point it appears to have had impact damage to the wooden corners - but otherwise this synth is in exceptional condition for its age.

The Midi on these is very basic and many people choose to upgrade the Midi capabilities.

100/110v unit - can be converted to 240v


The Memorymoog is a polyphonic electronic music synthesizer manufactured by Moog Music from 1981–85, the last polyphonic synthesizer to be released by Moog Music before the company was sold to management and renamed Moog Electronics. While comparable to other polyphonic synthesizers of the time period, such as the Sequential Circuits Prophet-5 and Oberheim OB-X, the Memorymoog distinguished itself with 3 audio oscillators per voice and greater preset storage capacity.

The 6-voice Memorymoog is considered sonically superior, and is often described architecturally as six Minimoogs in one unit. Each of the six voices of the Memorymoog is made up of 3 voltage-controlled oscillators that can be set to any combination of pulse (variable width), saw, and triangle waveforms and freely switched over a 4–octave initial range. Each voice also has its own 24dB/Octave Low Pass voltage-controlled filter.

Moog Music wisely included a discrete implementation of its famed, patented transistor ladder filter, which was first introduced in the Moog Modular systems of the 1960s and subsequently came into widespread prominence in the Minimoog. In Mono mode, the Memorymoog functions as a traditional monophonic synthesizer with 1–18 oscillators selectable in unison for powerful leads and basslines. The user may also specify any combination of Low-, Latest- or High-Note Priority keying and Single or Multiple Triggering, for an impressive degree of control.

A Chord Memory function (for single key, parallel chord "planing" effects) and an Arpeggiator are also included, while an independent LFO with 5 non-mixable waveforms allows simultaneous modulation of each VCO frequency, oscillator pulse width and filter cutoff frequency in any combination. Further, VCO-3 can also be used as a Low- or Audio-Frequency modulation source. With careful programming, audio frequency modulation using Oscillator 3 can produce convincing pseudo acoustic and FM-like timbres typically not associated with analog subtractive synthesis.

The Memorymoog uses Curtis CEM 3340 IC's as opposed to the discrete Moog oscillators used in the Minimoog and Modular units. With 18 oscillators, 6 voices, the Moog VCF and subtle on-board overdrive via the Mixer section, the instrument has a massive sound all its own and is capable of dominating the mix in which it is used.

Shortly after its initial release of the Memorymoog, Moog Music introduced the Memorymoog Plus (or Memorymoog+) as a replacement. The Plus featured a factory installed MIDI interface - making it amongst the very first electronic instruments to include a MIDI implementation - and a basic polyphonic and monophonic sequencer, the latter of which is used to control an externally interfaced monophonic synthesizer (via rear panel CV/gate/trigger jacks). The "Plus" MIDI/Sequencer package was also available from Moog Music as a field or factory retrofit for original "non-Plus" Memorymoogs.
