This is a very important feature in my workflow. I use it frequently to isolate a single simple midi track of the BIAB chord sheet with no embellishment to drive a number of Kontack VSTs. Using it now with the new session guitarists picked acoustic. Works well in the PC version of BIAB (although a bit tricky).

Which is why I am surprised this has not been resolved and is getting so little attention here in Mac Land. We have not seen one users other than the OP who is weighing in on if this works or not.

Megamads, if you are still troubled I can make a video of each button pushed on my PC version to generate the simple midi track in my DAW this weekend. It will be the PC version, but you may see something which could help. Just let me know.
