Hello Vinnies,
PitchFactor is a stereo processor so the connections you described should work.
You can set up presets for +/- up to 3 octaves and anywhere in between!
You can set up an expression pedal to change harmonies on the fly.
You can use it like a whammy pedal. The effect is called PitchFlex in PitchFactor.
You could run the original note on one side and the harmony on the other of you set Mix to 100% wet and set one of the pitches to Unison.
The Boss FV-500L should work with a stereo cable.
Alan
