"MIDI timeout: Logic Pro has detected a MIDI timeout. Please restart your computer, then relaunch Logic Pro. If the problem persists, update the drivers of all connected MIDI devices (including audio drivers with MIDI functionality) to the latest version. For instructions on removing older drivers, consult the manufacturers' documentation."
I have tried every blog and every link and every "solution" to this problem but nothing is working. I have to force quit Logic everytime now. I have not installed Pro Tools. There is nothing in my Root/Library/Audio/MIDI Drivers folder or my (unhidden) Users/Your Name/Library/Audio/MIDI Drivers. I am running Mac OS X 10.7.5 Lion and Logic Pro 9.1.8.
I was on Mac OS 10.6.8 Snow Leopard when the Midi Timeout started to occur. That's when I switched to to Lion hoping to fix the problem. No luck.
