The Yamaha DX9 is a spin off synthesizer of the family of the DX7 built by Yamaha. It uses FM synthesis and has 16 note polyphony; however, it only has four FM operators for sound generation compared with six on the DX7 (without alternative firmware ROM). It is the least complex of the DX range of synthesizers and has only 20 on board memory locations.
