Formant Plugin For PT

[Engininja]

Hi all.
Anyone got any hot tips for a plugin with a good sounding formant feature for mac RTAS/AAX. Want realtime processing and trying to avoid doing the REWIRE thing to ABLETON/REAPER. Would love 1 knob operation. Turn it left, turn it right kind of thing.
I'm sure there is a decent one tucked away in some kind of pitch correction plug out there none of which I have or have used. A lot of them seem to just want to preserve the formant where I want to change the formant a little and preserve the pitch.
Thanks,
SS

Waves Ultrapitch lets you shift formant only. Can't remember how good it is, haven't used it for years. Pretty sure you can get a demo of it.
