Digi MIDI i/o Duplicated and greyed in Audio/Midi setup

[xxicjoy]

This happens to me pretty frequently. My midi goes offline and in the AUDIO MIDI setup, my original MIDI i/o icon has been renamed Midi i/o 2 and greyed out. A second Midi i/o icon named midi i/o 1 is now present and can't be deleted. All I can do is delete the original one and redraw all my connections to it. And then restart. Pretty maddening. Any Fix for this? FYI i am using PT HD 7.4 cs5 on Intel Mac 4x 2.66 and MAC os X 10.4.11

Here you go. Just did it again this morning when adding IAC bus ports

I have a similar problem! I get the extra midi i/o devices showing up, but I can delete them. I don't have to reconnect everything. I do have to restart my computer to get my Motormix back online and my connection names. This happens often! I guess this is why it is discontinued!

Try this:

Go to MacHD>Users>your account>Library>Preferences>By Host and trash 'com.apple.midi.a bunch of numbers and letters.plist'.

Go to MacHD>Users>your account>Library>Preferences and trash 'com.apple.audio.audiomidisetup.plist'.

Empty the trash and restart, then see if everything is working.

How do you have the MIDI IO connected - directly or through a hub? Are you using the PSU or USB power for it?

Digi,
I will trash my midi prefs tonight and see what happens. I am running the midi i/o in one of the usb ports on the back of my mac pro. I do not use the power supply but I have one. I believe that if I hit the reset button on the midi i/o it creates more devices as well. I will double check. Thanks.

Nice call digi! The pref under "by host" I did not know about. Now I can hit reset without the duplicates showing up! And if it happens again I know what to do. Maybe Jean-Charles Deshaies should add that to the "ProTools Pref and Database Helper"! I love that little app.

It's good to see that I am not the only one having this problem.
Everybody I speak to from Digidesign or Apple have been saying that they have not see this before.
I have 2 x Digi I/O's and 1 MOTU 128 Express running on a MacPro 8 core intel with 16Gb of ram. Pro Tools 8 HD 2.
My digi Midi I/O's are always dropping out from the Apple AMS (Apple Midi Setup) program and putting new ones in.
Then I have to remap my Midi setup what a pain.
I have made a copy of my preference on my Midi devices so I can copy it back into the User/Library/Audio/MIDI Configurations.
This sometimes work but then my Midi I/O's are back there in grey, and again 2 new Midi I/O's have been created.
The funny thing is that my MOTU 128 is rock solid and always is there no drop outs.
I am starting to think because the Digi Midi I/O are only USB 1 there is the problem.
I have updated the firmware to version 2 like everybody tells you to do over and over again.
Also there might be something in the update to OS x 10.5.7 don't do it.
I never had this problem running my old Power Mac 10.4.x and Pro Tools 7.4.x
There seems to be alot about the USB not working on alot of devices running 10.5.7.
My Tascam DVRA1000HD has stopped mounting with the arrival of 10.5.7.
If I put it onto a machine running 10.5.5 or 10.5.6 all good.
Removing preferences dose nothing.
If any one comes up with a fix please let us know.

If any one comes up with a fix please let us know.

Have you tried trashing the prefs indicated above and/or using a power supply with the MIDI IO's?

[Aussie Mick]

There is differently a problem with OS X 10.5.7 running alot of USB devices.
I would say take your OS back to 10.5.5 or 10.5.6 this will no doubt fix your other USB devices such as printer.

Lets hope someone fixers the Digi Midi I/O

The PSU does not help. I will try a different port and see if that helps. I will also unplug other USB devices as well. However, I have had this problem since I got this machine with Leopard. So it's not a new thing with OS recent updates. I have had no other USB issues at all. I believe that the problem occurs when I close apps that are using midi. At least it seems that way.
