This is turning into a case worthy of Sherlock Holmes. My MIDI signal from my MIDI controller, a Yamaha Motif XS8 connected via Firewire, continues to randomly disappear for no apparent reason. Internal MIDI, say playing a VI from a MIDI track inside Pro Tools, isn't affected at all. It appears to be the Firewire MIDI.
When I first turn on the PC, all MIDI is fine.
If I leave the PC idle for a while, and come back, the MIDI connection seems to have disappeared and the only way to get it back is to reboot the PC.
I've triple checked that I have installed the latest FW driver, including uninstalling and reinstalling it.
Checked all cable connections
Made sure all PC sleep/hibernate modes were off (Win-10)
It is not necessarily Pro Tools related as the problem will occur whether or not I'm using Pro Tools.
A new twist popped up last night. All the MIDI was working fine. I created a MIDI track in Pro Tools and then wanted that track to play a patch on the Motif which I recorded onto a PT audio track. No problem. All worked per normal. Then, I spent about 1/2 hour doing some mixing/arranging with the session which didn't involve me using the MIDI controller at all. Then I wanted to use the controller to play a new part on a PT instrument track and the MIDI was gone again. Just, poof...gone! Can't use controller to play a VI and there's no MIDI out from PT to the controller either.
I'm at a complete loss here as to what to check, look for, try or anything else. Suggestions? Ideas? Should I call a priest?
