Sorry, didn't see your post until now! Operator error I'm afraid, I never selected "New"... now I can select the MIDI device, it reads the keys when I hit them, but OBS won't respond to the commands-

Solved I think, thanks anyway

Hello, I just installed the software and connected my Novation LaunchControl via usb, but MidiKey2Key does not allow me to select anything at all, it's greyed out. The only two tabs that I can open are "File" and "Help". The rest of the options are not working. Any help would be appreciated, thanks ...
