I guess I'm like many on this forum----just scratched the surface of what BIAB will do. I use it mainly for live play. I know the basics of selecting styles, arranging tunes, and adjusting some of the basic parameters. Beyond that---zilch! So far, so good for my purposes. If the laptop acts up on a gig, not sure where to start looking. I've got 2010, but have not loaded it as yet because of all the comments about crashes, etc... Things are working fine with 2009.5 and, at the moment, at least through New Year's, I can't afford any set backs or interruptions with faulty gear, computer, or whatever.
