You're right...they make for impressively authentic demos...but they also sound pretty cool to the player who does not want to use SMF.

I also agree that the excellent quality generic styles on the Yamaha lend themselves to a much wider usage, and, if I may add, they also provide a great basis for making your own styles using style assembly.

Having great "cover" AND generic styles would seem to be a "no-brainer" in encompassing the best of both worlds...kudos to Yamaha for having both...plus...an extensive third party style base unequalled by any other manufacturer.
