One really cool feature about this is that if you analyze a song and lay out a template with the analysis you will see it often "adjusting" to tempo bar per bar to keep up with the "live feeling" of the song it has analyzed. E.g. 92 BPM, to 93, to 94, back to 92, etc.

Once you have that template you can use it to modify/add your own chords etc but still keep something of a live feel with retards etc so that your song doesn't sound like a machine.

I think that is pretty cool.

Yes, I know you can manually do this anyway, but analyzing the pacing in a favorite song and then using that as a template quickly to create your own swing is pretty neat I think.
