This video, via synthpro, takes a look at a Moog Polymoog prototype. Here’s what Synthpro has to say about the video:
It is with much excitement that I bring to you a video clip of my prototype polymoog 203a this was probably made somewhere around 1975 and was developed by Dave Luce.
It is an Honor getting to own this work of art!!
Dave Luce, I highly respect your design, I have restored many polymoogs and they are so great, I understand what you were going for in the polymoog and 35 years later it is still a great instrument that stands apart from any other polysynth.
The Polymoog was originally released in 1975.
In the second video, he compares a production polymoog 203a and the prototype 203a
