Hi Al (for short), about your old software, did you try to run old Windows version compatible with your software on a virtual machine (vmware or VirtualBox).
About what you want to do with midi data can you give more details?
(control some parameters, do message translation etc.)
If you could give a couple concretes examples of midi fonctions you want.
I’m more familiar with music keyboard control than studio gear so That’s why I’m asking.
CTRLR can do a lot of things so there is great chance it can do what you want.
Stay tuned. Quimquim
