MIDI Controller

A MIDI Controller is a piece of hardware or software that sends Musical Instrument Digital Interface (MIDI) signals to control sounds, instruments, and effects. Unlike a synthesiser or sampler, it doesn’t generate audio on its own — instead, it communicates with other devices such as computers, virtual instruments, or hardware synths.

MIDI Controllers come in many forms: keyboards with velocity-sensitive keys, pad controllers for triggering samples or beats, fader/knob surfaces for mixing and effects, and even guitar- or wind-style controllers. They give musicians hands-on control over digital music production, live performance setups, and studio workflows.

Whether you’re playing notes, tweaking parameters, or launching clips in software like Ableton Live, a MIDI Controller is the flexible link between your creativity and your sound.
