I think it's unfair to say that melodyne "is good but not that good", since you're trying to do something celemony never said melodyne can do in the first place.
I agree, Loptec. I've seen a few people complaining that Melodyne won't do this or that.
It is an astounding piece of kit.
So what if it won't work your keyboard and drum parts out, or if it requires some tweaking in the note detection window when analysing polyphonic material?
Reading the manual is a real bonus. When I first got it I just bumbled round, and got bad results v e r y s l o w l y. I then studied the manual and practiced on random audio until I now get remarkable results quickly.
I say again, it is an astounding piece of software.
