Thanks, FBB, but as mentioned but not completely answered in another post on this topic, when I press, O I see a + only in one track. I have tested this repeatedly and cannot make Offset work as documented (although admittedly, the explanations in the Cakewalk and thrid-party books are very cryptic to say the least, almost as though the tech writer did not understand the function).
There is also another possibly related issue: when I turn Write on on a track, the perceived volume changes radically. Example: Fader set at -9. I click W on the track. The fader does not move but now I can barely hear the track even though it was strong before.
