I just want to see a workflow on whole complex backing track from start to end in BIAB. By "END", I mean before it goes other places like DAW.
If it's going to a DAW, why do the work in BIAB?
I do most of my work in the DAW. I generate the tracks in BiaB, typically creating multiple takes for each instrument. I just keep regenerating that track, and save each new take with a different name (BASS_1, BASS_2,
etc.).
If I had a solo that I wanted a
bunch of takes for, I might create a separate BiaB file with only the chord progression the solo plays over - say, 8 bars long - and set it to repeat a bazillion times. I'll export that out as a .wav file, and slice it up in my DAW.
Once I've got my .wav files generated, I fire up the DAW, and start slicing and dicing, choosing the best takes. I can always fire up BiaB and render some more tracks if needed. Easy peasy.
