Hi Rich,
just in case you do decide to use the track gain sometime, just a couple more
points:
1. For things like the gain dialog and the pan dialog which you can only open
for a single track at a time, the keystroke to open the dialog opens the dialog
for the focussed track - it doesn't matter whether or not it's selected.
2. Unlike applying the amplify effect, you can change the gain of a track
during playback.
David.

David, just to clarify, let's say that I have a project going with four
tracks, three guitars and a vocal. Let's say that the vocal is too low
and I want to bring it up in relation to the guitars. I select the
vocal track and make sure that the guitar tracks are not selected. I
then press shift-g and enter 3, for example. Do I still need to use the
"mix and render" command, which I was never aware of before this, or is
pressing shift-g and entering 3 sufficient?
