This is a performance from Spring 1981, forty years ago. I was hired by Digital Keyboards to modify the GDS Synergy synthesizer. I used a piece of white felt to make the instrument presentable while it was disassembled. It was a very early FM synthesizer that used the digital oscillator design from the Alles machine at Bell Labs. It is a credit to Mercer 'Stoney' Stockell, Tom Piggott, Dennis Breifel (RIP) and the crew at MTI Crumar. I offer this music as a credit to their work.
