Running on the slow computers of the era, he developed means of computing FM timbres to emulate real instruments such as bells and pitched percussion instruments, without needing inordinate amounts of CPU time to compute the sounds.

At over 100,000 units sold, it still stands as by far the best-selling synthesizer ever produced. It defined the direction of Yamaha's entire keyboard line for the next seven years after its introduction.
