VCS 3 music synthesizer made by Electronic Music Studios, London Limited, London, England, 1970

Music synthesisers became commercially available in the mid-1960s. Early models were very large and very expensive. The VCS 3 analogue electronic synthesiser - a modular analogue synthesiser made by the British company Electronic Music Studios - was practically portable and much more affordable. The circuit of an analogue synthesiser produced simple electrical wave forms which could be modified to imitate acoustic instruments or produce novel sounds. Many pioneers of electronic music in the 1970s used the VCS3, including Pink Floyd and Roxy Music.
