I didn't like those two demos either. Yamaha has always had weak drums. They just lack "punch". That's why I generally do drum work on external devices such as drum machines.
I do think Korg and Roland have always had the edge in the drum department.
You have some very interesting and well thought out insights on the new Tyros. Very informative.
