I'm not sure if it's just me or is something different in V-Vocal in X2?  To me, it seems like it sounds "grainier" or less pure than in X1.  Is this my imagination or is there something to it?  BTW, there was a tutorial somewhere in the forum that informed how to change the default settings in V-Vocal where the tuning is set to zero so you don't have to manually keep doing that every time you invoke it.

I remember this about the formant: http://forum.cakewalk.com/fb.ashx?m=917054

If you're working with take lanes V-Vocal doesn't mute the underlying clip in a lane.  So you'll hear both the tuned and original clip at the same time.  That's something different.
