In my vocal track I have notes here and there I want to adjust.   I have split several sections of my lead vocal track because of noise issues in between singing.    When I open Melodyne, I highlight an area of the vocal track that needs adjusting.   But later in the song there are more areas that I want to adjust. 
 
Having highlighted one section, it doesn't allow me to adjust any notes other than what is highlighted in that particular section.  Do I have to keep opening Melodyne every time I want to adjust a note in another section?   That doesn't seem right.   How do I open Melodyne once and adjust all the notes I need to in all sections of the vocal track?
 
Thanks!

Hi. Select the clips one by one, and bounce to clip. Select all the clips and bounce to clip. Then Melodyne will behave as you wish.
All the best.

Melodyne is applied to whatever clips you have selected not the entire track, unless you have selected the entire track. If I understand you correctly you are only selecting part of the track, so yes to edit a later part of the track that you have not selected then you have to open another instance of melodyne.
 
FWIW I think this is the way that most people would recommend working anyway.

You might find it easier to work with smaller clips though.  You just create a region FX for each clip, edit in Melodyne and then render it.
 
I do all my editing by phrase basically.  I don't want the whole vocal open at once because its too much information (I only listen to a phrase at a time.)  It also ensure that there is some variability in the way I edit.  I move all pitches and amplitudes manually to try to keep some feel, even taking things a bit more "out of tune" to create a bit of tension or drama.

^ +1 exactly how I work.

I tried working with smaller clips, but Sonar crashed - unless I did it wrong.   I selected a clip, opened Melodyne and adjusted a couple of notes.   Then I had to close Melodyne (since it was only for that clip) and had to select another clip and open Melodyne again.    
 
Dave:   I don't understand about rendering the clip after opening and editing in Melodyne. 
 
Thanks, everyone!

Rendering = bounce to clip = makes changes permanent and closes melodyne.
 
I use Ctrl+b for this, but I can't remember if I set that up or if it is one of the default key bindings.

Yes, small clips, and render as you go!

OK, I'm trying to understand.   "Bounce to clip" - this is done by selecting all the clips and right clicking on them (I'm not on my recording computer right now) to make the smaller clips one long one.   Then I open Melodyne.  Correct?  
 
Thanks!

If you have created a region fx -> Melodyne and are done editing, you will close Melodyne.  Then right-click on the clip you just edited and the context menu will have a selection under Region FX that says Render Region FX.  This is making the changes permanent.
