This didn't start (as far as I know) until I updated the Virus to the current OS. Notes get stuck and require resetting the MIDI drivers in Logic. I can usually get about 10 minutes or more of playing before the issue occurs. It happens almost always, however, when I click away from Logic, like to another Desktop to check email or something. It does happen though, I think, sometimes while working in Logic, without clicking away.
Logic X (10.0.0.7) and the Virus TI (5.0.8.00) are both current.
Is this a known issue? Any suggestions?
