Hello, I am using logic pro 9.1.8. All of the sudden, my M-Audio Oxygen 49 has stopped working. The controller powers on when attached via usb, but no input is registered. "Reset all midi drivers" in the preferences pane has not helped. I have tried deleting the controller from the control surfaces > setup pane, to no effect. Plenty of resets, computer and software. I have successfully gotten a different controller working. Any help with this is appreciated, not playing is driving me crazy!
