Premiere Sequence to Audition not working.
The process packs and trims the audio files into a directory; opens Audition; but then fails to open the multitrack, reporting a non-helpful generic error. After reinstalling several times, both Premiere and Audition with various versions; still failed.
Worked with support; cleared prefrences, archived common directorie, and reinstalled Premiere—still wouldn't work.
Work around was to go back to Premiere after the failure in Audition and save the project to a new filename; then in Audition open the new project file. It worked; but there were some clips out of sync? Could have been an issue with the sequence?
I ended up mixing in Premiere; editing out single clips into Audition and saving there; which were reflected in back in Premiere. One caveat; if the "Edit Clip in Adobe Audition" is dimmed, do a "Render and Replace" and try again.
Hope this helps.
