Let me start by saying I think this version (2.10.1) is the best version of prime to come out so far! BUT, I've been trying to add metadata and tags to my mp3 tracks in order to the new loop sections feature in my original tracks. I can't seem to figure out how to do it properly. If someone has successfully done this, please share your process.
NOTE: I use mostly Adobe Audition and Pro-Tools to make my tracks.
