Some times what I do is convert the tracks I want to audio, say, all but the bass, put the newly made audio in the audio track. Then mute all the biab tracks except for the bass and start auditioning styles for the bass track/s I might use. But, I didn't put a whole lot of thought into this. It's just something I started doing a while back 'cause it sort of works. ( I'm still using BIAB 2016 ) Having an actual feature would be great. But, I think that feature is already part of RealBand. Is it not?

Does the noise in your head bother me ?
