AJ,
when I had my Yamaha S950 it too had some audio styles. They sounded great but the problem I encountered was they could not be copied to a thumb drive or played from various folders on the hard drive. As a result I never found a way to use them in individual gig sets.

How do the Audio styles work on the SD9 Pro? Will they play from a thumb drive? Can they be copied to individual folders and played from there?

Backus Auyaplayer, maybe you can shed some light on this.
