I'm very happy with the styles on the Tyros2 and the S900.

They cover all the genres I play, and since they use mega voices, they are very good.

Probably why Wersi makes a point of saying that Yamaha styles can be used in their arrangers.

Why pass up a good thing when these great styles will make your arranger sound nearly as good as a Yamaha?

There is also a great abundance of third party styles available for Yamaha arrangers...all free.
