I can't wait to get back to it. I have a couple tunettes on my drive where I had drummed to an imporved guitar track only to find out that is not quite like jamming with flesh and blood.

Same here...   I have a few minimalistic free-form tunes that could benefit from this feature to more efficiently flesh them out.    In SONAR. 
 

Apologies - I didn't notice until a few minutes ago the shill/troll was back again, at which point I did the ban/delete posts exercise. So he doesn't repeat the fictional "no one can say anything negative about SONAR" B.S., for the record, his sole point was that Studio One has also had ARA tempo detection for a couple months, and he feels it's better (although he offered no evidence as to why). However this time he added an exciting variation of trashing Harrison Mixbus, as well as usual trashing of the forum community. 

I tried it on a free form guitar track and an instance of a drum vsti.
It tracked along like a good drummer should. - I shook my head in disbelief.
 
Tonight I plan to record a purposely time wavering "Can you play at all" track with maybe even a re-tard at the end. If that works too, Everyone at Cakewalk and Celemony gets the summer off, my treat. 
 
The forum software **** ed out ****.
It did it again! ****edForumSoftware! :-)

Here's a new video that explains the feature:

Thank you for that really well-done, informative video, Andrew.

One thing, though: It appears blurry throughout. I know sometimes videos take a moment to pull focus on YouTube, but this one never did focus. Is the problem maybe on my end? I was watching via YouTube on my iPad Pro.

Thanks again,
LJ

Very cool.  What does upgrading to Melodyne Editor or Studio add with functionality beyond the v4 Essential that comes with Sonar (as it relates to the Tempo Mapping feature)?

Great...   now my clever "In SONAR" comment is completely meaningless.     

Nice! Looking forward to try this on a few loosely played themes i never got around to finish, as it would take me years to fit the rest of the arrangement This will make it much easier
All the best.

Did you try changing it to a higher resolution like 1080p? It was initially set to that for mine and I noticed it was blurry. Changing it to 1080p fixed it.

I was amazed at how well it works. Did the same thing of dragging some random guitar noodlings (played without click track of any kind) into the timeline and playing a drum synth along with it. I had thought that maybe the hundreds of tiny tempo changes would sound kind of forced or glitchy, was very pleased to hear how natural it sounded, like two musicians totally locked into one another. Will experiment with some more expressive guitar phrasing tonight (i.e. drastic slow downs etc) to see how intelligently it detects.
