I would love a chromatic mode for the Quadravox+ algorithm, I think it is such an amazing harmonizer but is extremely limited to songs with minimal chord changes. Right now I get by combining two Polyphony’s, but it would be great if I could get all 4 voices from one algorithm and leave room for another algorithm afterwards(or combine two for an Octavox). I believe the plugin version of Quadravox has chromatic mode, so I would really love to see it implemented in the stompbox.
