Has anybody tried the free Native Instruments "stems" program?
 
I could never get it to work for me, and wind up using the methods posted in this thread

Just a heads up, if you do simply export each .wav, (which is the best way to export raw tracks imo) select all your individual clips on each track if you have edited, drag the start of the first clip of each track to 0 and then bounce each track to one clip.  Then export each clip, one at a time to your preferred file type.

It is time consuming to do it this way and possibly something the bakers might look at creating a "batched" way to do in the future as cross-platform collaboration is a necessary evil these days.

If you've gone to all this trouble there is no need to export your tracks, just drag and drop to your desktop, or anywhere else

Well here's a question:
Why would anyone want to mix stems instead of individual tracks?
I understand that in the old days it might have been necessary with limited hardware, but is there a reason to do it now?

Often its convenient to use stems. Suppose we're talking about 50 or 100 tracks do you really want to have to deal with all those tracks when a dozen or so stems will do much the same thing? I use buses to have like instruments together. Drums on one buss and guitars on another and so on. Once one has a balanced mix on the track level I do most of my mixing with the buses.

This is how I work as well.

One reason is that some mastering engineers will accept stems as sort of a half-way measure between doing a full mix and just mastering a stereo mix. For example normally if you get a mix and the drums need work, there's not much you can do without affecting the other tracks. If you get stems, you can process the drums prior to mastering.
 
Personally I prefer not to master that way; if there's a problem with the mix, I make recommendations and ask the client to redo the mix.

Those make sense, thanks for the clarification.  
I do most of my mixing with busses too (for demo purposes mostly).  
But when I hand everything to the studio/producer I'm paying to mix it, i'd rather work with the base tracks.  Otherwise i'm spending a lot of money while limiting his mixing abilities...

Stems to mastering engineer
Tracks to mixer engineer
