Hi, I installed some drivers for the tascam us122 i/0 and the mbox and i'm running lion osx.  Now Logic Pro gets stuck on checking for midi drivers.  I looked at previous post's about the subject and seen where someone was instructed to delete the file's in their midi driver folder.  Well when I go to that destination I don't see anything there.  I can't find where these things are located and i'm wondering if someone else has had this problem.

    Did you read this I posted a few weeks ago.

    (It's the mBox avid/digidesign driver causing the problem.)


    See if there's still a digidesign MIDI driver installed.


    It would be in Root/Library/Audio/MIDI Drivers.




    Also: Users/YourName/Library/Audio/MIDI Drivers

    I'm not using Lion but I've heard that Lion may make some files/folders invisible to the user, I wonder if that's the problem. Look for a menu command while in the Library folder.

    That's too bad, I thought the mBox would work with audio only, it's the Digidesign Core MIDI driver that's incompatible. Unfortunately many older USB devices broke under Lion.


    The ones that would work with the initial Lion release were broken after the last Lion update.


    You've tried the last US-122 driver Tascam released, version 3.40?


    If you've been with Apple a long time you know that continual upgrading of something or other  is part of the game.

    Studios will be using much higher end gear. The initial investment of a pro interface usually means driver support will last much longer. Both the mBox and the US-122 are discontinued devices. Also, Apple changes things at their whim and many manufacturer's will not support Apple's upgrade cycle, especially with consumer or semi-pro hardware. I do know that the US-122 still works on Windows 7, probably the mBox as well. Because of the large business base MS doesn't usually do anything drastic to I/O devices since there's such a wide variety of hardware that needs to remain supported.



    p.s. if you're running in 64-bit, might try running the Tascam install in 32-bit, see if it works, then switch back to 64.
