Okay, just to be clear, I think BIAB is an absolutely AMAZING program which does what it does better than any of it's competitors (I'm not even sure it has any). Maybe I misread Donny's first post (and if I did, I apologize), but it sounded to me like a putdown of BIAB users, and I thought that was odd coming from someone who used (exclusively) various other forms of NON-LIVE backing. For me, if it ain't LIVE, it's Memorex (whatever form 'Memorex' takes).

If your objective is to create polished backing tracks, then, like Ian, I think BIAB is as good or better than any arranger...and a heck of a lot cheaper.
