My main instrument is the drum set, and I listened to the original records and played those things myself in the late fifties. No doubt that the Audya has the most authentic drum sounds and the most authentic basic rock beat of that time. Tyros is also very good. The rest is pretty bad. There is one thing wrong with the Audya and with almost all arranger keyboards. The eight notes before 2 and 4 comes just a bit too late, and throws the basic beat out of balance. In jazz, blues, rock and latin, the drummer must know where to push and where to hang the notes to get a good beat. I think Tyros is better on this point.
