(Sonar Platinum)
 
My song is 13 hours long.
I can't seem to crop it.
 
The envelopes (dotted line) stretch on for 13 hours then stop. I looked in the event view and there are no events listed after 6 minutes. But the envelopes stretch on for 13 hours!? When I hold the (ctrl + a ) keys it selects a space thirteen hours long. I can't seem to find the event or parameter that is causing this. I tried cutting all of the the envelopes from the song and that did not work either.
 
I am wondering if I export my wave files/midi etc into a new project if that might fix this. Seems drastic...
 
 
 

I found an envelope down in the bus view that was on the master bus; I thought I had already looked there.. It was stretching out exactly to 13 hours and there was node there. Finally :).

WOW a 13 hour song, and I thought American Pie was long. lol.

I have an all tracks view that helps me find stuff like this. Hit the fast forward button and search the tracks for the errant node or event.
