HarmoniserFeedback - FreePlayer Guitar Effects demo
HarmoniserFeedback - sound demo. Rotate the guitar neck to get a harmonised 5th!
A bit raw, but we couldn't resist it! It doesn't have to be a 5th, of course, and with other dimensions to play with, you could fade all sorts of harmonies in and out selectively.
