i don't think you can do want you want easily in BIAB although I'm sure Jim knows a way but it sounds a little complicated.

it might be easier to do the following........

copy the BIAB file so you don't change it and can always open the current file

open the copied file in RB.

you should be able to select a midi track and load the vst. record a midi track hearing the instrument you want.

export the midi track as a wav or as a standalone midi file.

close RB and open the original BIAB file and import the audio wav or MIDI you just created.

BIAB is not a DAW. It's an auto accompaniment program and an amazing one. for some things RB fills the gaps easily and seamlessly
