P.S. Also rendering that Virtual Instrument to WAV, where chord track is sent to, from BIAB would be useful.

Example: BIAB with "chord track"+Virtual Instrument > when rendering audio have an option to "render chord track instruments"
...assuming you are using those V.instruments inside of BIAB as VST's, such as Guitar Strummer or similar.

Saving BB Chord Output track works, but this workflow would be much better.
