The Moog Opus 3 is analog poly string synthesizer released in 1980. The Opus-3 had 3 distinct sections for strings, brass, and organ alongside of two analog VCF sections, some simple modulation capabilities, an on-board chorus effect and a unique stereo panning effect found rarely, if at all on synthesizers of the time. While perhaps the companies' simplest synthesizer, it does retain the trademark Moog sound and remains a classic vintage string synthesizer.
