With its complex menus and lack of conventional controls, few learned to program the DX7 in depth. Yamaha licensed the technology to create the DX7, combining it with very-large-scale integration chips to lower manufacturing costs. FM synthesis created brighter, "glassier" sounds, and could better imitate acoustic sounds such as brass. FM synthesis, a means of generating sounds via frequency modulation, was developed by John Chowning at Stanford University, California. In the early 1980s, the synthesizer market was dominated by analog synthesizers.

It was the first successful digital synthesizer and is one of the best-selling synthesizers in history, selling more than 200,000 units. The Yamaha DX7 is a synthesizer manufactured by the Yamaha Corporation from 1983 to 1989.
