Yep, that's the downside to the Roland Favorites... ROM sounds and effects only. But you are right... on the whole, they are pretty much OK.

You MIGHT try a message to Richard and his Session Manager software on the R-A.com site. For the G70, it allowed you to copy OTS's into styles, I think in a batch format. A lot faster than doing it by hand, anyway...

Maybe he needs some encouragement to finish the BK version?
