Released in 1970 by Moog Music the Mini-Moog was among the first widely available, portable and relatively affordable synthesizers. It became the most widely used synthesizer in both popular and electronic art music. Patrick Gleeson, playing live with Herbie Hancock in the beginning of the 1970s, pioneered the use of synthesizers in a touring context, where they were subject to stresses the early machines were not designed for.
In 1974, the WDR studio in Cologne acquired an EMS Synthi 100 synthesizer, which a number of composers used to produce notable electronic works—including Rolf Gehlhaar's Fünf deutsche Tänze (1975), Karlheinz Stockhausen's Sirius(1975–76), and John McGuire's Pulse Music III (1978).
The early 1980s saw the rise of bass synthesizers, the most influential being the Roland TB-303, a bass synthesizer andsequencer released in late 1981 that later became a fixture in electronic dance music, particularly acid house. One of the first to use it was Charanjit Singh in 1982, though it wouldn't be popularized until Phuture's "Acid Tracks" in 1987.
