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.
