OPUS 3 - A polyphonic synthesizer producing Strings, Organ and Brass voices either individually or in any combination...and Moog engineering has created some truly outstanding features:

A chorus circuit for Strings and Organ with adjustable depth, speed and delay. Layered effects obtained using an articulation mode control which allows independent attack and decay contours for Brass and String voices. Five mixable footages in the Organ section.

OPUS 3 also creates powerful polyphonic synth voicings by combining chorus with the completely variable patented Moog filter and LFO modulation. A stereo mixer with panning and level controls places each of these three main outputs within the stereo image.
