Hello,

I migrated yesterday to my new MacBook Pro and I'm having a problem with MIDI.

The MIDI doesn't appear in TotalMix MIDI Settings :


Or any DAW :

I didn't understand it directly, but this is probably the reason why ProTools or Reaktor are so slow on startup.

When I open the OS X "Audio and MIDI settings" (Sorry as it is here in french I don't know how it is called in english) it is loading for a very long time and, after a while, it displays a error message saying that it could not load because of a MIDI manager :

"Audio and MIDI settings could not open the MIDI server, preventing you to consult or modify you MIDI configurations.
If you recently installed a MIDI manager, try to uninstall it and opening Audio and MIDI settings again. If Audio and MIDI settings doesn't work correctly after that, contact the manufacturer of the manager to get assistance."

I ran a new install of the latest drivers but it didn't change anything.

What should I do ?

Thanks for your help !
