I asked a similar question on the AB forum when KQ Dixie came out, because I don’t feel like going through 30,000 or however many there are DX7 patches and finding that 29,900 are electric piano or something equally overplayed… Somebody finally posted this useful-looking link:

Apparently the Suzanne Ciani patches live up to Ciani’s reputation as a top synthesist.
