Soundtrack Pro 5.1 export dropping levels
I tried searching, but can't find this anywhere exactly. One thing that seemed similar said to trash preferences or duplicate the project, or reinstall... and I don't really want to do that, but this problem makes no sense to me.
I have a 5.1 mix I'm doing, fairly complicated, just a lot of tracks, 4 submixes. I have everything how I want it, all 6 channels sounds good. When I export (I've done AIFF files, all separate mono files, and one 5.1 file, same issue) it drops the center channel considerably, but not all the way through. Maybe... 2/3 of the way though, it brings it back up to what it should be.
When I go to listen to the mix in Soundtrack after export, that's how it sounds. Simply changing the submix output to none, or any of the other ones, and then assigning it to its original submix again brings it back to where it should be. Export again, it moves levels around again.
Any idea what the issue could be?
Oh, and I've even tried assigning the offending channels to another submix that has exported fine, and same issue on export.
