I want to create a song that completely combines multiple styles, all the instruments from every part, from beginning to end, even if that would be discordant or redundant.

Why do I want to do this?

Right now I will sometimes set a style, export audio / MIDI into Logic, then set another style and repeat, sorting it all out in Logic. This way would make that a lot easier.

I'm guessing the answer will have something to do with copying tracks onto utility tracks, which I approach with fear and trembling because of the way BIAB seems to use random names for instruments. But, if that's what I have to do, that's what I have to do.

Please note, I am using BIAB MacOS 2021. I post this here because I doubt it's a Mac-specific question.
