MIDI I/O not working? Check the Audio MIDI setup

MIDI interface is not online.

Looking at the MIDI window of the Audio MIDI Setup (which, by the way, is an application located in a “Utilities” folder within the “Applications” folder; an alias might also be in your dock), you might notice that the MIDI interface is a lighter shade than normal.  This means that the mac knows that it was once there but today its not sensing its presence.

Closer observation of the MIDI I/O in the machine room shows that its power light is on but the ‘online’ light is off.

Here’s what I normally do in this scenario.

  1. Hold down the “Panic/Reset” button on the MIDI I/O until the “online” light illuminates. You will also see a light show from the other LEDs on the box.  This announces the unit restart.
  2. Hit the “Rescan MIDI” button in the Audio MIDI Setup app.  If the unit still doesn’t fully appear, then try step three
  3. Find the USB cable connecting the MIDI I/O to the computer. Unplug it, then plug it back in. This jolts the computer into rescanning its USB port.  This normally solves the problem.  If not, tell Jeff all about it.

Solution: In this particular case, this was a result of the Digidesign MIDI drivers not being compatible with OS 10.5  You can remove the DIGI drivers from the /Library/Audio/MIDI Drivers folder

OR

Update Pro Tools to the correct version for the OS.  In our case, PT LE 7.4.2cs2  for Mac OS10.5.6  Then, correct the permissions so that everyone can read and write to each Digi MIDI driver.

I’ve also had the “Unable to Launch MIDI server” when there were incompatible MIDI drivers from other manufacturers.  It just goes to show you that you cannot upgrade without breaking something.
