I say this with a smile . . . .
I can't see why pitch correcting - call it "smoothing" rather - should be a moral issue,
or anybody's business but my own. If I use it, it doesn't invalidate a good song if I've written one - it
enhances the production.
Paying as much attention to your voice as to your backing tracks only makes sense.

Is fixing a flat note or two any less moral than a single guy showing up to do a
gig with a five piece combo on a computer? And these softwares will also correct a bad note in an instrumental solo. Your option is always to re-record and put as much time into it as you want. But boy it's nice to have that fall back position.

It's also a great idea to use the software to check your vocal intonation before a final mix.
If you're going to pitch songs, the voice had at least better be in tune. Melodyne or the others won't put dynamics
in your vocal track - you'll have to work on that - but it will make sure that those emotional moments
are in tune.

Now coming from a guy whose hearing has a D note sound as a D in one ear and Eb in the other,
I love the software for being able to check the accuracy of my vocal tracks.
I sure don't see using Melodyne, or any of them, as a moral issue.
