two melodyne essential serial numbers, why?
 
take a close look I am having 3 melodyne essential serial numbers, one with earliest date the other two are of same later date.

Actually four, one I just get online, I think this the the update of the latest one in melodyne essential?!

You haven't said which version of Sonar you currently have . . . but if you see a Melodyne Essential version 4, that is the one you want, and I believe you have to register it at the Celemony site first to be able to use it inside Sonar.

Do you have Presonus Studio One as that comes with a licence for Leodyne Essential.

thanks for all the replies above. I was away for almost a year since I last used Melodyne Essential.
 
I am running Sonar X3 Producer on windoes 7 home pro edition.
 
From my old harddisk I saw I was having Melodyne Single Track as well as Melodyne Editor, are these two applications any good or they are replaced by Melodyne 4 Essential?
 

Editor is vastly superior to Essential, though this is a fairly costly (paid) upgrade. do you remember paying for the upgrade?

I was using the trial version of editor which not allow me to save anything. Just used it as a player.
 
How about Melodune Single Track? Is this obsolete?
