Sorry, I am having a little trouble understanding exactly what you are trying to do. On top of that not many others coming to our help. And finally, I am afraid that using a keyboard midi controller with BAIB is not the most efficient or practical workflow - software just don't support it well. I speak from experience on this last statement. My midi keyboard controller works like a charm through my DAW. So BIAB tracks goes to Reaper when the keyboard is involved.

Good Luck
