Hi!

I don't now if this helps any further now - but I recently bought Melodyne Essential (Version 5.1.1.) from Celemony. I saw the bundle with Nectar 3 but purchased it as a stand-alone. As Joanne Cooper's video warned me that it doesn't work very well a a plug in I used it once so far having exported the wav file from RB. Then imported as wav file back into RB after the tuning. Worked fine.

I am pretty sure this one and your "freebie" version are the same.
