I guess, if RealBand would be integrated into Biab as a window for instance, you would have a timeline sequencer right in BIAB. This means you could first let BIAB compose more than 7 MIDI tracks to 16 MIDI tracks and also have maybe 16 Audiotracks beside the MIDI tracks.

there would not be a problem with using different DAWs, as BIAB could stay a plugin.

I think it would be a very good idea to do so.
in a sequencer arranger you could freeze bars and notes, that do not have to be regenerated. and you could arrange loops and tracks better. this would make BIAB more flexible.
you could also combine 3rd party loops and MIDI-tracks better, which would be a great feature for electronical and classic music.
especially you could in many auditracks record a group of singers and for each singer in a different track, for chorals for example or for duetts.

Also there would be the ability to have a better mixer and plugin panel for the audiotracks right within BIAB.

there would never be a reason to convert tracks to another DAW, because you could do everything right in BIAB.

I could imagine also an automatic audiotrack composer out of samples in BIAB with automatic pitch-shift and tempo-adjustment, like it is in Magix Music Maker. should not be too hard to do the code for that.

For now, BIAB is just nearly only for POP/ROCK and JAZZ MUSIC, this new ability would also open the software to vocal music, electronic mixing and classical music. I would be very happy, if you do these new features in a newer version.
