Forgot how to bounce/clean-up a comped track!

Either I’ve forgotten or there’s another issue going on.

I minimize the lanes so all the good parts appear in the main track lane. Then I select them all, go to Audio, click Bounce Selection.

I get a message saying, “There was a file error during bounce! The function had to be cancelled!”

Am I doing it totally wrong lol? I remember it being super simple.

Thanks!!

seams to be correct, are you sure that you are just selecting Audio?

Have you correctly situated your range markers at top of timeline?
