Notable instruments: Projectron - A device built by Alan Parsons as an analog sample playback device, similar in general concept to a Mellotron. The Projectron consisted of a 24-track tape machine, with each playback channel routed to a voltage controlled amplifier; each VCA was in turn gated by a key of an attached keyboard. The device was used on the albums I Robot, Pyramid, and The Turn of a Friendly Card. But preparing tapes was a cumbersome process and the device was maintenance-intensive, so as soon as a Fairlight CMI became available to Parsons, he switched his sampling activities to that. Parsons scrapped the Projectron sometime after 1980, and no photos of it are known to have survived.
