On the MIC interface is NOT embedded the harmonizer, normally I use the VST Voice Machine 1.0 as stand alone version
locate the VST: Voicemachine.dll and make: open with : FST.
The FST system wil run up the VSTi without VSTHost engine.
then connect the MIC out from jack to Voicemachine IN and the OUT to the FX MIC server IN.
Connect also the keyboard midi out to the voicemachine and you can change the vocals chords.
MAYBE in future we wil embedded the choir harmonizer with our Elastique pro engine, up to 8 Voices.
For this I need to redraw the AUDIO 8 Bank EQ, editing the all object with photoshop and then we are ready to open a new Page.

James, if you are interested, I can teach you how to change the whole OS graphics object..
