This video, via Saved By Technology, offers an overview and hands-on demo of a rare Polyfusion modular synthesizer.
Here’s what they have to say about the video:
In this video, we take a tour of one of the original modular synthesizers (circa 1977) from Polyfusion, an offshoot of Moog. Learn the basics of modular synthesis and explore the sounds of this legendary and very rare vintage synth at the Saved By Technology showroom in Toronto!
This unit was recently completed refurbished by Jay Lemak and Brock Golden from Toronto-based synth repair company Synths When (facebook.com/SynthsWhen), who also hosted this video.
