I recently purchased a Presonus Studio 68c audio interface and now Guitar Rig 6 is not working in Logic Pro 10.7.5. It runs fine on my Intel iMac as a stand alone. And even though there is an audio signal present on the channel in Logic, there is no signal running through Guitar Rig. And guitar tracks already recorded using Guitar Rig 6 are playing back with Guitar Rig processing as well. Guitar Rig was working fine in Logic with my previous interface, a Focusrite Clarett 4-pre, but the 4 pre is unreliable as it doesn't always mount upon starting up my Mac. So I bought a new interface and now Guitar Rig 6 doesn't work with either of them. I have gone through all of the suggested steps in re-installing Guitar Rig, i.e. deleting Guitar Rig from the NI folder, deleting the Guitar Rig 6 plist from preferences and deleting the com.apple.audiounits.cache and then re-installing Guitar Rig. Nothing has worked. Any help would be greatly appreciated.
