<< I appreciated learning about the audio performance track, and you spoke so highly of the things that can be done with such a track, so I am very curious about some ways that I could use the feature to my advantage...>>

Here's one:

"Obviously, like everyone in this thread, I just want the simple option of making a few clicks and saying "OMG... I love the riff the guitar does right there... let me freeze those bars!!" and then to continue working knowing that I have locked and frozen those bars in place for that track."

That's exactly what an Artist Performance Track does... exactly. The easiest, most efficient and quickest way is to save the entire track. All you have to do is open the track menu window and select Save as a Performance Track and those bars are securely locked and frozen in place for that track. But if you want to select a few bars and save them, an APT will do that too.

I don't know the workflow or tasks you'd rather do in BIAB to either avoid having to go back and forth between a BIAB project and a DAW or if you'd rather not have to use a DAW at all. So I don't know what particular tasks will work to your advantage. But, an APT can likely do any task that you currently leave BIAB and take a DAW in your present workflow, and do it without opening a DAW.

An important thing an APT does is to convert virtual BIAB tracks to a physical audio file. APT's expand BIAB's mostly MIDI based and virtual audio manipulation into a physical audio format. I'm confounded by the lack of attention toward the User track APT given by PG Music. An APT is a User RealTrack the same as the better know UserTrack but is more powerful in a project than the single track of a UserTrack.
