I have to ask, why do you want to do that? What version of Melodyne do you have now? Is the version that comes with X3 an upgrade?  This might help answer your question more directly.

No. I have the same thing that comes with the upgrade purchase. Melodyne Singletrack 2.1. I'm paying for both and I want to keep both. I can sell one or transfer one to a friend. I think I will just delete it before I upgrade and see what happens. I'll probably wait a bit anyway.

You would have to contact Celemony about that question.

OK, Thanks Noel.

Last year I purchased Studio One (which has the bundled Melodyne Essentials).  I also had a second license of Melodyne Essentials.   I eventually upgraded the second license to Editor, but for awhile, I had two separate Essentials licenses.  As Noel commented, the best way to keep track of this is via Celemony's site.  Once you log in to your account, all of your licenses will show up separately, each with its own serial number.
 
BTW, the downloaded Melodyne file will show as "Melodyne Singletrack", regardless of whether it's Essentials, Assistant, Editor, etc.  (Your serial number determines what version to install).
 
I'm about to install X3, so I expect to have a third Melodyne license soon.

Thanks jonD! I've got mine for sale at KVR now. I see no reason to have two. Worst case I would give it to someone who could use it.

Well, I needed to check my iLOK licenses for Melodyne and SONAR (I own EDITOR 2.1)... I had to check my iLOK account to see if version 2.1 was there... iLOK now has an APP to manage your iLOK instead of going to their website.  I liked it and wouldn't have even known about it if it wasn't for this version of SONAR... made it a breeze to just fire up MELODYNE in an audio track and see it do its magic without crashing SONAR... this ARA thing is pretty cool.
