The Sequencers and drum machines

The early 1980s saw the rise of bass synthesizers, the most influential being the Roland TB-303, a bass synthesizer and sequencer released in late 1981 that later became a fixture in electronic dance music,[141] 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.[142] Music sequencers began being used around the mid 20th century, and Tomita's albums in mid-1970s being later examples.[120] In 1978, Yellow Magic Orchestra were using computer-based technology in conjunction with a synthesiser to produce popular music,[143] making their early use of the microprocessor-based Roland MC-8 Microcomposer sequencer.[144][145][failed verification]

Drum machines, also known as rhythm machines, also began being used around the late-1950s, with a later example being Osamu Kitajima's progressive rock album Benzaiten (1974), which used a rhythm machine along with electronic drums and a synthesizer.[121] In 1977, Ultravox's "Hiroshima Mon Amour" was one of the first singles to use the metronome-like percussion of a Roland TR-77 drum machine.[124] In 1980, Roland Corporation released the TR-808, one of the first and most popular programmable drum machines. The first band to use it was Yellow Magic Orchestra in 1980, and it would later gain widespread popularity with the release of Marvin Gaye's "Sexual Healing" and Afrika Bambaataa's "Planet Rock" in 1982.[146] The TR-808 was a fundamental tool in the later Detroit techno scene of the late 1980s, and was the drum machine of choice for Derrick May and Juan Atkins.[147]
