The AT1 is used to correct pitch within the vocal range and features a few different modes. The first one is the Auto mode - with this mode, the pitch will automatically be bent to the nearest true exact semitone. When selecting the MIDI mode, the pitch will be bent to the incoming midi note. The last mode is the manual mode, in which the keyboard on the pedalboard can be used. Features: Modeled by x42
