Like some of the sibling posters, I'll use this opportunity to share my feelings on Ada. I checked it out a few years ago, and I was amazed at how much it has to offer. Despite being designed by committee in the late 70s, Ada has many

Unfortunately you can't add any more operators to the DX10, however you could probably add multitimbrality! Yamaha's YM2164 sound chip at the heart of the DX100 is pretty well understood, and very similar to the later YM2414 used
