I use it for all my harmony vocals. I have gotten to the point to where my lead vocals are mostly on-pitch -- but my harmonies -- yuch! ... and I pretty much slam them with melodyne. But since they are harmonies, you can't really tell -- or at least I can't.

I only have melodyne essential which only works on single lines (editor works on polyphonic tracks). Editor would be nice, but essential works for me. I probably should sweeten my lead vocal lines also, but I haven't done that yet, I just keep singing them until I get it close enough.

Great tool!
