Thanks Mac! That's pretty much exactly what I wanted. You might want to consider adding an option for chord tones only in there (rather than the whole scale), but it is great as-is as well.

Thanks again-- I don't think I would have found that on my own in a YEAR of using BIAB!

I'm certainly "having fun"... way more fun than rote endless scale practice. I've done that since I started playing sax and things just don't get internalized that way (I still mess up simple things like a minor scale sometimes, even after doing it a gazillion times). I think you can get to a sort-of hybrid thinking/motor-reflex playing with that method of study, but with BIAB learning I'm developing my ear/listening and timing at the same time, and also having fun! Before I would force myself to do half an hour of scales, and suffer through it. Now I turn on BIAB and play, and the HOURS fly by!
