The Mooer Pitch Step is a pitch shifter that allows you to control pitch in real time with the foot pedal.
You can choose between the switch mode that turns on and off by stepping it deep and the sensor mode will take effect just by putting it on. It also features a SUB mode for pitchdown, the UP mode for pitch-ups, and an S+U mode that can control the range from -1 octave to +1 octave with pedals.
It can also be used to create a harmony with a single button.
