I've been learning the various editing aspects of V-Vocal and have most of the basics now figured out, but am struggling with a few quirks.  One of which is as follows:
 
I activated V-Vocal on a bass track and just the act of doing that (with no additional processing or editing) introduced a "warble" in some isolated areas within the track.  Any tips how to prevent/correct this behavior?   I was under the impression simply creating the initial V-Vocal track would not in itself do anything to alter the result.  Or am I misunderstanding something?  I also tried running the eraser over the problem areas just to be sure and no change in behavior.  I did however notice in a YouTube video that maybe this could be related to spikes in the signal which V-Vocal is confusing as too much gain and reacting to it?  The problem areas that create a brief warble do seem to be in the same areas where "spikes" tend to appear on the graph.  These "spikes" do not correlate to any such spikes in the original track, but they do tend to correlate to fast notes.
 
Thanks for any help on this...

Did you apply V-Vocal to the entire track? It doesn't always work well on large clips. Try splitting it into shorter clips and just work on the bits that need correcting.

I did indeed.  The whole track needed slight pitch correction.  Wow, so the size of a clip makes a difference in the behavior/performance of V-Vocal??

Yes, the size of the slice can matter. The same often goes actually with Melodyne as well (at least plugin).
There's been dozens of posts about pitch correction problems with material that is somehow distorted or otherwise
harder to "read", even with a raspy vocal. I could imagine there can be such sounds on a bass track as well.

Is there some procedure that can be done in V-Vocal to correct these glitches?   I've tried the eraser tool, no change. Only other thing I can think of is to experiment with manually altering the spikes in the graph where the warbles occur?

V-Vocal works best when you deal with short clips (as noted above) that are clean, free of bleed, distortion etc.
 
Depending on which version of SONAR you're running, V-Vocal may not be the best tool for correcting Bass and Melodyne might be better. But it depends which version you've got.
 
V-Vocal is great for correcting Vocal pitch/timing etc (hence the name ) but there are probably better solutions available for instruments.

I'd only use V-Vocal for vocals and bass tracks. The bass tone does have mild distortion in it (Sansamp).  There is no signal level clipping involved on the tracks.  I have Sonar 5PE and 6PE.   Which are the first two years V-Vocal was included IIRC. 
 
I was going to try a pitch correct plug for the bass like Gsnap but couldn't get it to load for some reason.  Would something like that be better than V-vocal to pitch-correct bass?  I only require random nudging, nothing major.

(duplicate entry removed)

V-Vocal has to first determine the pitch of each note's fundamental frequency, which can be difficult or even impossible depending on the nature of the tone. Distortion and other effects greatly reduce its ability to map pitch correctly. Your best strategy is to identify (by ear) specific parts of the track that truly need correction, split clips to isolate those parts into their own clips, and then apply correction to just those clips.

My theory has always been...
If you need to fix a whole track using V Vocal, Melodyne or any type of correctional software,
Then you are better off re doing that whole track over again.
I say this of course because of personal experience using both V Vocal and Melodyne.
