Moog Opus-3

Moog Opus-3 Image

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.

I love this Keyboard. The Organ, String and Brass sections are very flexible. It's got a real Moog meat and grit to it. Best part about it is the super wide +5/-4 pitch wheel. Get your slide on! :)

It's 49 key polyphonic but not in the traditional discreet oscillator grouping fashion. It's a Divide Down architecture using a high frequency TOG similar to other string machines. But it has a discreet 4-pole low pass Moog filter, a 3 phase stereo chorus, and a very nice LFO with delay and vca fade in. Certainly it's just a single filter which can do legato triggering or re trigger on every key; not ideal for every style of playing.

Strong points are certainly the String chorus and high/low pass filter (does not resonate as it should not). Brass filter is excellent.

Nothing moogy about this "synth". It's basically a string/brass-organ. It's not a synth, and it's not at all the polyphonic Moog in the way that you dream of it to be. Trust me.

Not played or met one, but i would guess, if its like many other string synths, then it would be fully poly.

How many notes of polyphony? Everyone is talking about it but I do not see a number.
