Quote Wikipedia: .... Yamaha Corporation has always been a major partner of Korg, supplying them with circuitry and mechanical parts. In 1987, shortly before the release of the M1 Music Workstation, Yamaha acquired a controlling interest in Korg's stock. The takeover of the company was amicable, with Katoh drawing up the terms, and the two companies continued to independently develop their product lines and compete in the marketplace. After 5 very successful years, Katoh had enough money to rebuy most of the Yamaha share back in 1993.
