What makes you say that, musicvid10? A wav editor is something that doesn't currently exist in the Magix range as far as I can see, so i would have thought that and Spectral Layers would be natural additions.
But use Samplitude for more than a minute and you quickly understand why it could never be a 'streamlined' application: it simply has too many features, all of them implemented with unbelievable thoroughness. There hasn't been space in this review to even mention half of the existing features that haven't changed in Pro X, and as the review period wore on, it almost became a matter of pride for me to try to find an audio function some other DAW can do that Samplitude can't. Every time I thought I'd succeeded, an email conversation with Magix's support team shattered my illusions. (Talking of which, in a world where music software companies are increasingly moving towards paid-for support plans, it's worth noting that Samplitude users get unlimited free telephone and email support.)
And yes, Tim, that would include a full direct wave editing suite of tools and fx - you might want to download a demo. I recommend the Pro X Suite http://www.magix-audio.com/us/samplitude/
