Osanai, a Tokyo University graduate and noted accordionist, regularly performed at Kato's club accompanied by a Wurlitzer Sideman rhythm machine.

Buoyed by the success of the DA-20, Keio released a solid-state version of the Rhythm machine, the Donca matic DE-20, in 1966.

KORG was the first company to feature effects on a synthesizer, and the first to use a sample + synthesis sound design.

[3] Yamaha Corporation has always been a major partner of KORG, supplying them with circuitry and mechanical parts.

In 1989, KORG recruited the design team from Sequential Circuits as they were relieved of their duties by then-Sequential owner Yamaha.

KORG has since diversified into digital effects, tuners, recording equipment, electronic hand percussion, and software instruments.
