I agree with "TOMTOMSF".The PSR740 has a very
comprehensive"GROOVE" function that has
many parameters that can be set,totally
altering the original style in so many ways.
I can understand then why PSR9000 owners
should be upset that this feature was not
carried over to the Yamaha flagship,considering it is based on the PSR740 but with all the bells and whistles.
Official!
