The most prominent MIDI problem on Lion is caused by a Digidesign MIDI driver which is obviously not fully Lion compatible and causes all MIDI applications to hang while trying to initialize this driver. The system's Audio-MIDI-Setup is for example also affected (/Applications/Utilities/).
- Install the latest Pro Tools 10 update, or:
- Remove the Digidesign MIDI driver DigiDioMidiDriver.plugin from this folder: Macintosh HD/Library/Audio/MIDI Drivers/
- Please contact Avid regarding a Lion compatible MIDI driver for your Pro Tools hardware.
