LESLEY JUDD and FRED HARRIS introduce a compilation of items from the recent series of Micro Live. Few rock and pop records are made today without the help of sophisticated computer-based synthesisers. They can produce the sound of any instrument and replay strings of notes more accurately than session musicians. Micro Live traces the development of such synthesisers, from the 19th-century Telharmonium, to the Fairlight Computer Musical Instrument which impersonates an orchestra.
