Logic 9 Freezes on Screen Splash when "checking MIDI Drivers." I need Help.

What custom MIDI driver do you have installed? Something from Digidesign/Avid? There was a compatibility issue in their older drivers with 10.7.

Hello! I have the same problem, but with a twist. Protools works on the same MBP, using the built-in Apple MIDI stuff, and the a usb keyboard.

Could it be, that AVID and APPLE are not "playing" well together?

I don't think it has anything to do with "playing well together", it seemed a simple bug in the Avid MIDI driver.

Sorry! What I meant was, that Logic freezes when checking MIDI drivers, but PT works smoothly, on the same MBP. I was wondering if PT had somehow "moved in and taken over".

Nobody seems to have any ideas. Hmm Maybe I'll try re-installimg Logic.

Hi

Not likely to help.... the problem is most likely with the Avid/Digi drivers, so all you should need to do is remove them.

Where do I find them? Would ProTools still work? 😮

Thanx, CCTM! It worked!

Very similar problem!!

I recently switched from an imac running os x snow leopard to a newer one running lion. I use protools Le 8.0.4 with an avid mbox, gen 003. This combo always worked great under snow leopard. I installed it in lion and it also works like a charm, except i just bought logic pro 9 from app store, and it seems to get stuck in "checking midi drivers" at startup.

I looked at several previous posts like this one, and found the solution was to delete the old digidesign midi drivers from the library>audio>midi drivers folders, which i did and now logic is apparently working fine. Problem is, obviously protools doesn't work now. So it's either one or the other with this solution. There are 4 plugin files in this folder: digidesignfirewiremidi.plugin, avid mbox promidi.plugin, digidesignmbox2midi.plugin, digidiomididriver.plugin.

Am i going to have to keep deleting/restoring these files from the midi drivers folder whenever i wanna switch from logic to protools in the future?? Is it safe to keep doing this long term, or is there another solution i haven't found?

Also, does anyone out there know if it would be helpful to upgrade to protools 8.0.5? Or would i just be asking for more trouble?

Thanks in advance...

This is a terrible problem. It seems like a such a simple bug that has just not been fixed. I had this same problem over year ago which rendered my digi 002 (or Logic 9) useless. I'm running Lion and I installed the most recent update over a year and half later. Still not fixed. Extremely dissapointed with somebody. Shame on you.

I'VE SOLVED IT!!!!

******** thought they could stop me 😉

Remove

DigiDioMidiDriver.plugin from Library -> Audio -> Midi Drivers

DigiDioMidiDriver.plugin is evil.

Hi

Yep... should be "Shame on AVID" for not supplying drivers that work?

CCT

I removed all of my MIDI plugins from the library folder and it still gets stuck on the splash screen.

thank you i tried it and it works very good

thank you so much..

you are amazing 🙂
