Hey guys,
 
Is there a VST,  capable of adding harmony to a track of vocal audio...     whose harmonies I can play (indicate) in realtime with a MIDI keyboard?     Or,  if not in realtime,  sequence some MIDI pitches onto a parallel MIDI track,  and have it control the VST that way?

Example:   Girl sings on an audio track...    I can then play my MIDI keyboard and get the instant harmonies (of her voice,  pitch-shifted and formant-corrected)  I desire that way?    With no chipmunks or nasty artifacts?

This used to be easy,  live,   with Digidesign VHM5 hardware... it should be a breeze in the DAW domain,  no?

Thanks,   ras

iZotope's Nectar 2 has real-time pitch control of harmonies via MIDI.

So does Antares Harmony Evo
