Problem with V Vocal when switched from X1 to X2

The original clip will not mute. Anyone else having this trouble? Thanks!

One reason I switched to Melodyne was that V-Vocal clips would mute and unmute unpredictably.
 
I also think Melodyne sounds better.  It would probably be the best $100 you ever spent if you do a lot of vocals.  In addition to fixing pitch and pitch drift, I use it to correct timing, reduce breath and other non-musical sounds, and to smooth out note volumes so less compression is required.
 
I sometimes fix little artifacts like pops, but I usually find it easier to do that in the actual wave before transferring to Melodyne.  (Tip: Drag-copy your wave to another track before you start chopping it up. )
 
 
By the way, to all the haters who don't like vocal editing, I will say again that 1-Melodyne and V-Vocal are just effects like compression, EQ, etc.; 2-singers have been comping together takes for decades; and 3-when the feel is right I don't want to lose it or wear out the singer over little things that I can fix.
 
Not too long ago a musician was giving me a hard time about what he called micro-editing vocals and said, "[group name withheld] didn't need that to record [song name withheld]."  The song in question was a Woodstock-era record and I really like it and the group; but when I listen to it now, the off-key harmonies really jump out at me.  Times change.

I'm sure it's not worth saying this, as you seem to be a fairly experienced V-Vocaller, but make sure you work in short, clean clips with good signal level, free of bleed and with no other Fx applied.

go with melodyne editor2, they have a lot of good videos to help with the learning curve...

Staying with V-Vocal is cool if it's working for you; however, I found Melodyne super easy and the free videos on their site are great—plus I am happy to provide tips are as the other users here.  I just have the monophonic version: Melodyne Assistant.  I will probably upgrade at some point but I don't need the polyphonic version now and I don't want to take a chance on a new install corrupting my works-in-progress.
