file-->export-->selected tracks
christ, i've been doing the deal where i solo each track and export mixdown...i don't know why i didn't do this before. i just gave it a shot, and it's easier/simpler than all hell.
edit: i just noticed that there's one downside to this feature, even when using the copy option - if you have a bunch of files on a single track(due to overdubs or whatever), each individual file is copied to the destination folder. i was hoping that all of the files would be rendered to a single .wav, but that's not the case. the .xml file that refers to the copied tracks does save all your fades/edits, but it still doesn't help if the files are headed to another DAW.
i wonder if cubase 4 has made any upgrades in this dept....i know that in protools, if you want to combine a bunch of regions on a single track into a single file, all you have to do is select the entire track, consolidate it, and then it write it to a new file.
