James, this version has a few extras.
A couple extra bands. But also, very interesting, it has the ability to look at a reference song of your liking, take a snapshot of the EQ of that song by analyzing it. Then you can apply that as an EQ pattern to your song. Ozone has that capability as well, but this is a cool capability when you're thinking about EQing or adding compression to something, that you can have as a starting point something that you think could be a good starting point to work from.
I anticipate in one of BitFlipper's upcoming articles on this series of tools that he will explain the nuances of that.
Kalle mentioned that the Melda series has a hit on the CPU. I've heard that as well. But I've also picked up that the recent release (8.02) does address related aspects of that and there is less of that concern as a result.
