Hey, Nigel...thank you very kindly for your interest, and for posting this old picture.

As unreliable as the Polymoog (a 203A model) was when I first got it, a friend helped me upgrade the instrument so it rarely gave any issues, and it stayed in tune much better...it had a 71 note (E-D), velocity sensitive, semi weighted keyboard (one of the first synths to be so equipped) and it was fully polyphonic, meaning all the keys would sound...it was splittable three ways.

AND...no midi whatsoever on any of the keyboards...it was still a gleam in the eye of Dave Smith, of Sequential Circuits and Prophet 5 (among others)fame.

As the song says, "Those were the days, my friend...."
