The signature
Natural fix to full robot, in one move.
Turn the TUNE knob up and the retune gets faster and stronger — from a slow, light correction to instant retune locked to the nearest chromatic semitone. Nothing else to set.
One knob — natural to snap.
Under the hood
One knob, and it does the work.
