I think the SY22 is big time underrated. Programing is not that bad once you get the hang of it. Two things that would be awesome on it 1) user samples, 2) analog filtering. I'm not sure exactly what it is about this synth, but there is something special in there.
I've multisampled most of the factory patches (left out the boring ones) every key is sampled at 4 velocity layers, and some patches are 20secs per key.
Let me know if you have any questions or requests for future sample packs (I'm working on a more contemporary sounding bank right now!)
Cheers!
