Donny, I don't think it's the drum sounds on the Audya as much as the drum GROOVES that sound different from the Tyros. The audio drums are recordings of REAL drummers and the pocket that comes along with them as opposed to MIDI drums which are notoriously sterile and align to the exact measure.

Sometimes a drummer can play a little ahead of a 4/4 count to give a song a certain feel whereas I don't think you can micro-adjust a midi drum to do the same.

I don't know if I'm explaining this correctly, but if you spend some time with the Audya, you get a sense of a better feel and groove to the beat more so than the Tyros and the Pa2xpro.
