Mutator is installed via the Auto-Tune Central app. It can be authorized to your computer or iLok. Beginning the trial and downloading Mutator does not require installing everything in the subscription—you can just install Mutator. I'm of course going to check out the other plugins while I have the trial.
For me it, it will likely come in handy for character voices and some other creative vocal effects. I had my eye on the Throat plugin, which this incorporates a little of that with length and width. It's similar to formant shifting, with a little more flexibility with the two parameters. I'll probably check out the Throat plugin during my trial.
