  "description": "The pitch-bending pedal: Position sweeps the note from where you played it up to an octave (or down, or a fifth, or a dive two octaves down), gliding as fast as Glide lets it. In Manual, Position is where the bend is: put it on an expression pedal. Rise bends up once a beat and Wobble sways up and back in time, as far as Position says.",
