I'm using Sonar 8.5.2 and I discovered that tracks created in old project files, possibly Sonar 7, were sometimes very quiet or did not respond to the pan settings. Not all the tracks, just here and there. I created a new track and moved the audio to the new track. That fixed everything but I wouldn't mind knowing exactly what happened and why. Thanks - rev

One obvious thing springs to mind.  Has this project been accidentally set to Offset Mode?

Offset Mode! That sounds familiar, I'll look it up. Thanks!
