Hi JustAnOldMuso,
I'm coming around to this approach as well...do as much in BIAB as possible and then bring it to RealBand for finishing touches. I'm only on my 5th song, and so I'm slowly refining how to work with things.
Regarding your follow-up questions, I'm about to read Noel's next post which I hope solves the issue, but FYI:
are you saying you have no rt's listed in rb ? That's right.
please go into further detail on your work method in rb. I'm still trying to iron that out, but I created in BIAB. Opened in RB but wanted to add some other real instruments.
by instruments do you mean genning pg content OR PG
loading vsti instruments in a rb track ??
