I got Studio with no regerts or regrets!
 

Editor doesn't have the fancy sound manipulation tools, with the EQ, Overtones, etc that Studio has, right?
 
I'd say that part is worth it.  It seemed really process intensive when I was manipulating things as a plugin, but got some really cool sounds with it that could then be bounced down to a track to free up that processing power.  

I thought editor had all the tools but was just one track at a time where studio is multi track? $50 sounds like a good deal tho, im still using editor 2 they want $112 for me to upgrade ;) 

Upgraded to Studio last month.  No regrets or problems. 

When I upgraded to Melodyne Studio 4 (From Editor 2) a while back, it really was a no brainer, since there was hardly any price difference to just upgrade from Editor 2 to Editor 4. Seems they really want us to have the full Studio version, by making it so affordable . . . ah temptation . . . so I went for it, and have really been pleased with the stability and extra features included. I've used every new feature included, and especially like the stand alone version.

Give us the link address for the $50 offer

This is the Cakewalk site . . . why not just go to the Celemony site, see what's available for you depending on which version you own.

Why not noynekker? Because I thought this was a site helping users, help each other! Apparently you think differently! I'd rather not search through pages of info, if I can get directly to what I'm looking for with the help of a fellow user. Hope this explanation helps.

It would at least be helpful if you let us know which version of Melodyne you are currently running so we can possibly do the legwork for you.

Or which features are important to you.
