MIDI instruments are electronic devices that use the MIDI (Musical Instrument Digital Interface) protocol to communicate musical information. They can include keyboards, synthesizers, and drum machines, allowing musicians to create and control sounds digitally. MIDI instruments do not produce sound on their own; instead, they send data to other devices, such as computers or sound modules, which generate the actual audio. These instruments enable musicians to record, edit, and play back music with precision. They can control various parameters like pitch, volume, and timbre, making them versatile tools for music production. MIDI instruments are widely used in both live performances and studio recordings.
