I may probably add that both Samplitude and Sonar come with their own interpretations (and algorhythms) of a Melodyne-alike editing, too.
I am however not sure whether I like the idea of Apple licensing things from Melodyne, for a variety of reasons that I won't go into right here, the main one however probably being that this could take the wonderful Melodyne away from others (I couldn't imagine how such a deal could be anything else but exclusive). This could even be bad for Logic users, simply because quite some of use seem to work with other applications from time to time, too, and not having Melodyne available in those anymore can't be a good thing in my book (as you might've guessed, I'm not much of a friend of proprietary formats).
I do totally agree that something needs to be done in the area of audio editing in general,though, and probably specifically in the area of what we may call "liquid", "elastic" or whatever.
i have recently gotten my Cubase 5 update, and while I still can't seem to get warm with the workflow (even if I started sequencing with Cubase), the built in VariAudio functionality is really nice - and quite some of the other audio editing options are as well.
For a start, it'd probably be a good idea if Apple improved the internal stretching/pitching algorithms, maybe implementing them into a Melodyne-alike interface later on. For most of the things I'd like to stretch/pitch, the algorithms coming with Logic are barely useable, whereas the MPEX algorithm supplied with, say, Cubase is quite good already.
Anyway, whatever improvements might be done, I'm sure they'd be highly welcomed by the majority of users.
