Should I be embarassed to admit I had never heard of the Multimoog until this one showed up on our doorstep? The Multimoog was a Moog monosynth made between 1978 and 1981 and I’m not sure I understand how it was intended to fit into the Moog product line, or what is “multi” about it. 

A contemporary of the Prodigy, it looks cheaper, with the one-piece plastic body of synths like the Sequential Pro One, but has a lot more modulation routing options for making strange noises, and a little pitch-bending ribbon controller. Perhaps it was intended as an alternative to the Prodigy for weirdos. Like the Prodigy and other “budget Moogs” like the Rogue, MG-1, and its 1-oscillator little brother the Micromoog, it offers AR only, not ADSR, for its envelope.

It has a full Pratt-Read keyboard assembly which was clackety and in need of new bushings, and also thoughtfully offers these easy-access removable panels underneath to make adjusting the key contacts easier. “How clever and thoughtful of Moog to do that,” I thought, before realizing that this amounted to an acknowledgement on their part of how unreliable this whole system is.

Work Done: reflowed all pin and wire connectors as this suffered from the same kinds of cold-solder-joint intermittent problems as all of its Moog contemporaries. The physical construction inside is kind of clumsy, involving a surprisingly large metal pole and an absurd number of staples. New electrolytic capacitors and rectifier diodes for the power supply, cleaned controls, rebuilt Pratt-Read keyboard, tuned and calibrated.
