Intelligent harmonizer plugin

Create a intelligent harmony plug in in the vein of the TC VoiceWorks units, Akai Deccabuddy, or Antares Harmony Engine. The ability to define a diatonic key or key off of MIDI is ideal. Per part formant, pan, "randomness", and pitch variation can be included along with per part doubling effects and perhaps portamento. All this running through Elastique would be quite nice I imagine.
