Hello de Nobbi, welcome to the forum.

Not sure if this is useful but this is my method for composing/recording with BiaB.
In step 5, I record either my bass guitar or my Korg Krome.

1. In BiaB build your backing track
2. In BiaB, mute the unwanted instruments
3. Export the backing track to your hard drive as an MP3 file
4. Import the MP3 file into your DAW (For me it's Studio One)
5. In your DAW, play the MP3 file while recording your instrument on a separate stem
6. In your DAW, mix the BiaB backing track and your instrument recording to your liking
7. Export the mix to MP3, WAV or whatever format you want

For me there’s no better place in the band than to have one leg in the harmony world and the other in the percussive. Thank you Paul Tutmarc and Leo Fender.
