I hope that this is not fall-down obvious but I am working on a great way to use BIAB Soloist tracks.

When you have created a soloist track in BIAB that is CLOSE to what you want, first render it to .wav or .mp3, then import it to your DAW. Cut/Paste to suit and use the segments as needed.

I'm working on a demonstration and I will post it in this thread later today.

My description leaves a lot to be desired.
