Pitch Shifter (Wheel)

A synthesizer’s pitch shifter wheel is a control that enables the user to alter the pitch of the sound the synthesizer is producing. The real-time implementation allows dynamic and expressive changes in the sound’s pitch. A variety of effects, including harmonies, octave shifts, and original sound compositions, can be produced by pitch shifting. Others may use a similar control, like a joystick or ribbon controller, to achieve the same effect. Some synthesizers have a dedicated pitch shift wheel.
