"This is the prototype of the Moog Prodigy, called the Moog Prodigy Xpander. This is the ONLY one I've ever seen.
This tabletop module was going to compete with the Oberheim SEM, but Moog Music in the late 70's decided to go with the keyboard version of the Prodigy, and many of them are still in service today.
It works perfectly, sounds incredibly fat, and it's oscillator sync sounds so much better than other analog synths.
I was a rep/dealer/consultant in the 70's and 80's to many golden age companies including Moog Music, (Williamvsille, and Buffalo factories,) Polyfusion, Sequential Circuits, Oberheim, Pearce Amps, and was a consultant to Les Paul.
Owning this for synthesists, is analogous to being a guitarist and owning Fender Stratocaster 001.
Most Moog experts weren't aware of this prototype, but being a rep, and living just 10 miles from the Moog factory, gave me an advantage to obtain rare pieces like this. Tony Marchese was the head engineer on this rare piece.
I met Bob Moog at the age of 19 in 1973, and he became my mentor, helping me in those early days to learn all I could about electronic music.
You'll need a MIDI to CV convertor to use this.
Obviously, this is for true Moog fans, and collectors."
