Thank you!

The one I have, that I used here, is the Melodyne 5 Editor, but Melodyne Assistant does all the same stuff except polyphonic instruments such as pianos i.e. Assistant only allows one track at a time, but for vocals that's all most of us need. The Essential version is pretty good for a starter option, but, unlike Assistant, it does not have phrasing, formants and certain dynamics, but most other things. Good thing is, if you buy Essential and find you need the other bits you can upgrade and you only pay the difference in price between the two so you don't lose. Essential seems to be half price at the moment too, maybe a Black Friday thing, who knows, see here: shop.celemony.com/cgi-bin/WebObjects/CelemonyShop.woa
