MIDI 1.0, or Musical Instrument Digital Interface, is a technical standard established in 1983 that allows electronic musical instruments and computers to communicate. It transmits information about musical notes, timing, and control signals, enabling devices to work together seamlessly. This protocol uses a simple data format, sending messages that include details like pitch, velocity, and duration of notes. MIDI 1.0 has become a foundational technology in music production, allowing musicians to create, edit, and perform music using a variety of digital tools and instruments.
