OK, I fixed it all by myself! When I originally installed it, there was a point it asked something about "Pro Tools" and I declined to install whatever it was as it seemed to be just for PT - I use Cakewalk, duh? Turns out it also contained the "RELAY" utility program. Now it's working and extremely well. This is pretty powerful. It seems to have the harmonic following ability very similar to Surfer EQ2 (which I own and love) as well as a lot of presets such as voice "nasal tone" correction, "boxy" correction, etc. All the presets seem to work well on my male Elvis/Cocker voice with harshness - but not so much anymore.
It can even do Waves "Vocal Rider" type of voice leveling.
I would consider it a must-have after messing with it for just about an hour. Really loving Izotope these days. In the last year, I've acquired RX7 Standard, Ozone 8 Advanced, Neutron 2 Advanced, and now Nectar 3. All of them are space aged compared to anything else I know of and really speed up mixing and mastering with seemingly pro results.
