I have a Mac-Pro Quad core with 8g of ram and running Logic 9. I'm using a Motu Micro Express midi interface and up till now everything was fine. It seems when i press the G key on my midi controller my midi tracks wether it be external or software gets completely wiped out. I don't understand what could be the problem. First I thought I had a dead key on my controller so I took it to the shop. I had another keyboard, hooked that one up only to realize it wasn't the controller becasue it did the same thing. I even sent the interface back to the dealer and they sent me a new one..same thing. I reinstalled the drivers also. One thing I did notice is that in Utilities I can't get the test to trigger the modules.My last resort is reinstalling Logic but I wonder if that will work. I checked all the settings I could think of that would be causing this but i'm at a loss right now. Any assistance or nuggets of information would be great. Thanks.
