I tried Melodyne and didn't like the workflow much.
I already had V-Vocal from earlier versions of SONAR, and rely on it, and understand how to use it effectively.
I've used it to tweak vocals, and monophonic bass lines, and in one case take an audio bass line and extrapolate MIDI notes. Worked great.
V-Vocal works great in X3.
You bet I have no interesting in listening to folks say "V-Vocal is dead", and telling me I should just accept it and use the inferior product that comes bundled with SONAR X3. (Do not compare V-Vocal (free, bundled) with the Melodyne Editor (you have to upgrade to it)).
I do feel sad that V-Vocal is basically only available to folks who already have it from earlier versions of SONAR... I hear R-Mix was pretty cool too, although I never used it.
If anything, this whole journey reminds us that you have to take the promo material for a new version with a big grain of salt. Bundled extras don't really matter. They might be fantastic, but there's no guarantee they'll be around in the next version. It's the built-in features that matter. *Cough* take lanes *cough*.
That said, I love V-Vocal. It allowed me to produce music and songs that would not have been possible for me to do at the time, without it.
