To expand on this request...
There are many midi based styles available that were made for keyboards. To enable BIAB to integrate those styles was one of my requests in the past. Pipeline's proposition is interesting to me in the sense that I can see it as a potential to use a keyboard style sections in BIAB arrangement, by simply adding a track to the mixer.

For example, a User Midi track could be specifically made for intros or breaks, ending etc. With Utility track functionality development on horizon, that could be very useful as there would not be shortage of mixer tracks for elements or smaller parts.
