The Opus-3 is one great little synth. It was designed by Herbert A. Deutsch from Hofstra University who originally nudged Dr. Robert Moog into building synthesizers and later served as director of sales & marketing for Moog Music. Herb also wrote the owner's manual. The sounds are broken up into 3 categories: Strings, Brass and Organ. Strings and Brass have their own separate VCF (filter) sections, the Organ section has none. The Opus-3 also has 2 sound outputs for an early stereo effect with panning! It's a colorful little synth with clearly laid out sliders and is fairly straight forward. It has classic analog Moog sound quality and is a great source of some string and lower octave techno-organ sounds. It is used by Stereolab, Kraftwerk, Zonetech, 808 State and The Rentals.

Had one of these in the mid 90's that I found in a pawn shop for $300. The brass section controls didn't work and the brass section sounded just like the string section. Probably the brass section didn't work. However, the string section sounded pretty good. The organ sounds I didn't like though. For a Moog, I was dissapointed.

oh.....the love affair I had with this synth. Such a fun sounding unit with full polyphony. And the filter.....it could really conjure up some "won't get fooled again moments" when the lights were dim. Had two and couldn't for the life of my keep one working right for more than two months. I spent probably 8-12 hours trying to get the horrid, melted rubber foam off the circuit boards. Anyways....beautiful sounding thing. Never buy one off eBay and sample it the moment you get it. The memory of my two Opuses lives within the digitized realm of Kontakt now.

An organ through mono synth processors. It's resonant bandpass filter gives some nasty wah effects. Classic string synth. You can use it just as a combo organ if you want. I will never sell mine.
