Synthesizer V Vocal Synth

Hey guys, anyone using this software?
To be honest I am amazed how expressive and musical it can sound and it's intelligible.
This english female voice is also impressive

.
The issue is that it can't be played live, notes can at least be recorded via midi keyboard but well, then you need to edit the vibrato and legato/portamento. I am also concerned about how can dynamical phrasing be done, but on the other hand I mostly see it useful for generally less dynamic, "pop" oriented music for which you would squash it with a compressor anyway.
I always wanted to compose also that kind of music, which generally requires having a solo vocal with lyrics and this seems like an amazing tool to enable making that kind of demos.
So I am really interested what is your experience if anyone is using it.

Cheers!
