I am accustom to using Midi form my keyboard to trigger the notes used in a Vocal Harmonizer. Using my Guitar, without midi, to produce vocal harmony has me stumped. The manual was a bit unclear.

If I am not using guitar and not midi, and I select a “Scale” for a song I’m singing, what happens to the harmony when I change the key? Must I select a new scale?

I would like to plug in my guitar and press a button to get the vocal harmony.

Thank you, John C.
