I recently bought and installed Melodyne Studio, which I believe is the top level tier. (Correct me if I'm wrong.) All I know is that it has more bells and whistles than I really need. But I did need some of those bells and a few of the whistles.
In any case, as a result, I haven't been using the integrated version in Mixcraft because all the ads say is that it is only the Essential version. Hence, I've only used Studio standalone. Imagine my surprise to discover that Studio showed up in the integration into Mixcraft. I'm tickled pink.
I use the integrated version all the time now. Thanks guys!
