Seeins how the only thing I ever run stand alone are Melodyne and TRacks...what's the great benefit to "stand alone"?  How do you guys use it?

It's a minor convenience for me.  No big deal.

It is a quick way to audition/modify kits/pieces and grooves or maybe just to learn/investigate a certain feature within a given drum vi. It saves me from having to fire up the DAW and associated hardware required to host a vi. You can save any grooves/kits/pieces you modify to be called up later in the DAW.
 
I use the stand alone mode for kontakt or dedicated piano vi's for practicing or creating new/modified sounds, again, without needing to fire up the DAW.
 
With my setup I just find it a quick and convenient way to work sometimes.
 

Same here,
It's convenient to quickly open to start jamming or getting quick ideas down without fussing about loading daws.

Sweet!!! Thanks for the heads up.
