Michael, have you thought about just rendering to wav (or other ) files [save special> save song as...] and just dealing with them in a daw?
I also have thought about trying to do style changes in songs in BIAB, but honestly I always prefer a super straightforward dealio, so that's how I approach style changes. And that way, I can "mix" (hyuk) midi and real with no worries...that's just one benefit. And let's say I want a tempo change, too...boom. Just render in that tempo...without worrying about if you are doing it right.


Since my pipeline is always going to daw anyway... it's a no-brainer for me to just do it that way. Way more control over everything in a daw, anyway.

^For what little it may be worth to you, sorry I can't be of more help as to the actual help request. Color me the perpetual newbie.
