Can you exclude a specific midi keyboard?

Is it possible to config Rack to exclude a specific Midi keyboard from it’s search? If another program has keyboard first, then Rack crashes. I’d like to run the two programs on the same PC if possible.

I thought that the sound card would be the problem but using WASAPI seems ok to share. This midi input problem is a stumbling block though.

If Rack is crashing for any reason, that’s a bug. Instructions for reporting:

Ok, done. In addition if there is a workaround for now that would be helpful.
