Yamaha DX9 | Vintage Synth Explorer May 05, 2017The DX9 was a not-so-special spin off of the aggressively popular DX7.

The 9 was released as a more affordable version of DX technology back in the day. The difference between this and FM7 might be in the output stages, which would have some noise and grunginess, and therefore more "warmth" to the sound than the computer-based FM7.
