"The -> Jazz Scale Suggester System may just be your ticket. It reads BiaB chord changes and presents you with just what you may be looking for."

I'm always amazed and astonished at the great info I get in this forum. This does sound like just the ticket I was looking for. But I'd be really surprised if BB/RB couldn't do the exact same thing but in a much better way, in terms of the quality of accompaniments generated. I'm also surprised - especially if Mac sees this as a useful part of the regimen - that this feature has not yet made it's way into BB. Seems like an easy one for them to implement given what they've done with BB over the last (?20+) years.
