'The following MIDI port could not be found, you can reassign to one of the following devices, or make sure it's enabled under MIDI Devices, etc' - what are possible reasons for Sonar failing to see the MIDI port? In this case it's my MOTU Traveler interface.
 
I can't enable it under MIDI Devices because it doesn't even appear in the list.
 
Thanks - rev

Reboot solved the problem - no cause found.

If Windows doesn't see it, Sonar won't either. Next time, try unpluging the USB cable and replugging it.

Makes sense. Thanks.
