I just posted a question like yours. Did you ever find a way to import Premiere timeline to Audition?
I haven't found a way to do it either... only one clip at a time. Audition will import XML files as a session, but Premiere cannot export them. Premiere now has the ability to export OMF's, but Audition cannot import them. This OMF functionality was added for ProTools users, but what about a way to get the entire Premiere sequence into an Adobe product (Audition or at the very least Soundbooth)? Where's Dynamic Link for this?
