Demo of the classic Elka string machine
The Rhapsody String synthesizer was built from 1975 till 1980 by the italian company ELKA. It was one of the more widely spread (read sold by thousands) string machines then. The list of users includes EM acts like Jarre, Tangerine Dream (Virgin years and some), Vangelis, Klaus Schulze (only a tour or two in the mid seventies). And also Supertramp and other pop bands used it too. The Rhapsody 490 was the little brother to the better known 610.
