A MIDI controller is a device that allows musicians and producers to create and manipulate music using the MIDI (Musical Instrument Digital Interface) protocol. It typically features keys, pads, knobs, and sliders that send digital signals to software or hardware instruments, enabling users to control various aspects of sound production, such as pitch, volume, and effects.
MIDI controllers come in various forms, including keyboard controllers, pad controllers, and control surfaces. They are widely used in music production environments, such as digital audio workstations (DAWs), to enhance creativity and streamline the music-making process.
