I havent tried that program yet, but I expect that your assessment is a reasonable conclusion.
But that is changing as we type here.

For now, its a great (and fun) tool for pulling the handle on the "slot machine" and seeing what you get.
If you like what you get, it wont be radio ready, but it may be very good for pulling into a DAW and using as a work-up stencil.

This morning I have been trying out AUDIMEE which is a very easy to us voice AI that will take my vocal stem and convert to other voices and adjust by semitones.
My voice has limitations. As a consequence, deriving things from my voice has limitations...

but damn the program is impressive. And I am just using the free version so far.
