Roland E-4 Voice Tweaker

The E-4 Voice Tweaker is an outrageously jammable box of fun that harmonizes, auto-pitches, vocodes, loops, and glitches your voice and anything else you feed it. Flip through hands-on controls to manipulate the sound, and chain in AIRA Compacts and other electronic instruments and let them ride in perfect sync.
