I've not used Audition except superficially so have no feel for how its engine works. I assume you've tried going to track 4 . I'd go on the ARSC website and ask who else is using your program. Sorry I can't be of more help.

When I attempt to do Mixdown>Entire Session, Audition drops tracks 2 and 3 and presents just track 1 as the completed mixdown. Scenario: I pre-recorded 1 hour of radio broadcast on 3 tracks. Track 1 was the music, Track 2 announcements, and Track 3 final instrumental cross-fade to close. I saved the multi-track and did a mixdown, no problems, saved the resulting wave file. On review I found that I made a mistake on one of the voice clips. I opened the multi-track session, deleted the bad clip, and recorded a replacement voice clip in the same location. Then I made all the timing adjustments to the end of the hour, saved the multitrack under a new name, and then did Mixdown>Entire Session. The resulting mixdown presents all of track 1 Mixdown>with the correct spacing, but leaves gaps for all the cuts on track 2 and track 3. I closed Audition, reopened the multitrack session, same thing happens. Is there a setting I accidentally missed that is causing these two tracks to be blanked? They are not on MUTE. (I am not stuck as I can always just correct the finished mixdown, but that will leave a ragged transition at the end. I'd like to understand what is going on here. Thanks for any help, Jay Bruder
