Thanks for your reply. If you read the manual, you will see what a MEGA VOICE is. It's NOT intended to be played live. You might get unexpected or undesireable sounds. Because how can you make sure that you always hit the key with same velocity?

Dance Drum Kit: I compared the Data Lists of PSR2000/PSR9000 and TYROS. they are same. And from history I know that whenever YAMAHA creates a new sample, they name the drum sample different. That's why I say, the dance drum kit is the same.
I could be wrong. Could you post a sample for dance drum kit, like the kicks and snares?
