What is a MIDI controller?

A MIDI (Musical Instrument Digital Interface) controller is a device that sends MIDI data to other MIDI-enabled gear or a computer. It lets you control and shape parameters of a sound or software synthesizer, such as volume, pan, and modulation.

MIDI controllers come in several forms, including keyboards, drum pads, wind controllers, and DJ controllers. You will find them in music production, live performance, and sound reinforcement, where they control digital audio workstations, synthesizers, and other MIDI-enabled equipment.
