Moog • Sonic Six
The Sonic Six is an old, simple, and rather interesting machine. It's an outgrowth of Moog's expansion in the early seventies, when it took over a smaller company called Musonics, which made a synth called the Sonic V. Moog took the Sonic V design, updated it with more Moog-like features (S-trig, three-stage Minimoog-like envelopes, etc) and released it as the attache-case-mounted Sonic VI.
It is an early duophonic portable synthesizer. It has some modulation capabilities not found in other small Moog models, and the sound...due to the odd filter design...actually has more in common with something like the Oberheim SEM modules. However, rather simple VCA envelope and VCF filter sections make this an easy synth for any user.
Not commonly seen, they were actually rather durable devices and used ones generally (if proper care was taken of them) are found in good working order. It was designed for home use so it is light and portable and has a built in amplifier and speaker. It's a budget Moog synth that is probably more obscure than useful these days. But it has been used by Freddy Fresh, Stereolab and Spectrum/EAR.
