I posted in the last DX7 chip thread about Dexed's interesting history. I know that at least one of the original developers frequents this forum. Dexed is a fantastic emulation. I remember Raph Levien mentioning that one of the most elusive details of the DX7's implementation that contributes to its signature sound is its quirky attack envelope stage. Also, one of the biggest remaining mysteries about the DX7 is the source of its trademark 'harsh' quality. It has a much harsher, warmer, and more distorted quality than any of Yamaha's other FM synths. Even decapsulating the OPS chip hasn't thus far definitively revealed the source.
