Sometimes after seconds, sometimes after 20 minutes. So now, every time I open Pro Tools I only have a short time to use midi until it just randomly stops working. Until suddenly, while playing and without me changing anything at all, it stopped working again. So I restarted Pro Tools and it worked again! But only for a short time.

Up until yesterday midi has been working perfectly fine for me, but yesterday I suddenly had no midi input while working in Pro Tools from both my midi-devices (A Roland TD-4 e-drumset and a Studiologic SL88Grand midi-keyboard). I've got a problem with my midi input devices in Pro Tools 12.7.1 on Windows 10.
