Mario,
Thank you for trying. I was probably not clear on "percussion" part.
Any Midi drums from BIAB Midi only styles (or any Midi track for that matter from BIAB Midi styles)
I am strictly talking about BIAB Midi only styles (not outside midi import) and how to get lines (tracks) from these into already created arrangement.
P.S. Loops are another animal, it is easy, there is a loop "picker".
Thank you.
