In 1921, Yamaha acquired Nishikawa & Sons in Yokohama after the death of its founder, and continued to manufacture Nishikawa organs and pianos until 1936. Magna organ (1934) Magna Organ introduced in 1935, was a multi-timbral keyboard instrument invented in 1934 by a Yamaha engineer, Sei-ichi Yamashita. It was a kind of electro-acoustic instruments, i.e. the acoustic instrument with additional electronic circuits for sound modification; especifically Magna Organ was an electric-fan driven free reed organ with the microphone sealed in the soundproof box, instead of electrostatic pickups used on the electrostatic reed organs. Early design of Magna Organ was a kind of the additive-synthesizer that summing-up the partials generated by the frequency-multipliers. However, it seems difficult to achieve polyphony without
