One program is a DAW and the other is a notation program such as Sibelius. It could be another DAW or any midi host program. How do I use a single midi keyboard across the two without fiddling the midi settings in the program every time I make a switch? Is it even possible? Of course, I could buy another keyboard so each host has its dedicated keyboard assigned but my workspace is limited, plus I would need to reposition my body every time I switch between two keyboards. Not to mention extra money to purchase.
