Also thanks for the reassurance that BIAB AI looks ahead and I don't have to worry if it will get things mostly right. It's a load off my mind to know that I can just enter my lead sheets and go with it.
Don't give up so easily. I may not be correct about it making no difference in BIAB whether you set many key changes or not. This really merits further testing.

As for those who would consider any modulation a change of key, I do understand. I think this stems from the way jazz theory is taught now, with an emphasis on scales and modes. "In my day" - the early 1960s - we learned it more organically.
