The manufacturer intended this synthesizer to be an instrument that would operate as six Minimoogs would do at once encased into one housing, but everything turned out quite different. The synthesizer was developed without the participation of Robert Moog, and appears to be the last model released before Moog Music went bankrupt.
Memorymoog is a full-featured polyphonic synthesizer, it can play six voices simultaneously and each voice is a mixture of three voltage-controlled generators (VCO).
Unlike Micromoog, where VCO is built on discrete elements, analog memory chip VCO CEM3340 is used in Memorymoog. This move cut the cost of each VCO (there were 18 of them in the synthesizer), but this affected the sound. The sound of 3340 is not bad, just different from the traditional Moog sound we got used to. This chip was widely used in Oberheim, Roland and Doepfer synthesizers.
Each voice has its own dedicated VCF. And there Moog decided not to economize - the key element of moog-like sound remained the same. The low-pass filter circuit which was used in the early products was put in there as well. Each of the six filters has a cutoff frequency, resonance and modulation depth adjustment.
There are also wide modulation possibilities for creating complex sounds. The built-in LFO has five different waveforms, and can be sent to modulate VCO (FM and PW), VCF cutoff frequency. In addition, one of the three oscillators of each voice can serve as a modulation source.
Memorymoog provides chord memory and arpeggiator functions. There’s a bank storing 100 presets for your settings.
