 OS X MIDI Device Hang

Fri 23 Mar 12 @ 6:48 pm

I've come across a few users now who have had problems with the Virtual DJ hanging at the external devices stage.

In Audio MIDI Setup under OS X, the MIDI Studio also hangs.

This problem can be caused by a problem with some drivers. To fix:

Open a terminal
sudo -s
cd /Library/Audio/MIDI Drivers

Move all the files in this folder to a backup folder. Retest.

Now you can move the files back one by one until you get issues - usually the Digidesign ones.
