Donald Buchla (born April 17, 1937) is a pioneer in the field of sound synthesizers, releasing his first units shortly after Robert Moog's first synthesizers. However, his instrument was arguably designed before Moog's.
Buchla was born in South Gate, California, and studied physics, physiology, and music.
Buchla formed his electronic music equipment company, Buchla and Associates, in 1962 in Berkeley, California. Buchla was commissioned by avant garde music composers Morton Subotnick and Ramon Sender, both of the San Francisco Tape Music Center, to create an electronic instrument for live performance. Under a grant from the Rockefeller Foundation Buchla completed his first modular synthesizer in 1963. The result was the Buchla Series 100, which he began selling in 1966. Buchla's synthesizers experimented in control interfaces, such as touch-sensitive plates. In 1969 the Series 100 was sold to CBS, who soon after dropped the line, not seeing the synthesizer market as a profitable area.
