im in cubase 5 and just got done with all my edits and then i go to start mixing and my left guitar track stops playing completely. the meter still shows sound, as does the one in podfarm. but nothing is coming out. i have the two guitars routed to a group and theyve been working just fine in stereo all night but the left guy just stopped. its not muted. fader is good, volumes on all the pod and lecab stuff is just fine. it stopped as soon as i loaded a track preset on it. i dont feel like its something stupid and obvious i just overlooked but it could be. any suggestions?
