Now I need to figure out how to remove the last 15 seconds of silence as I trimmed the outro down by 4 bars ....
I spotted a volume blob on one of the tracks at the original finishing point that I think was the cause of that happening.
Nope, that didnt work. Bah.
Before you export (after selecting "all"), position the cursor where you want the end to be and then use the bottom left button in the "Selection" box of the Control bar. Only the highlighted selection will export.
That's a quick work around.
Sometimes I find the problem in less than a minute and there have been other times where the "extra length" is caused by something that takes hours to find.
