The MIDI (Musical Instrument Digital Interface) specifications serve as the essential framework that enables electronic musical instruments, computers, and other related devices to communicate and synchronize with each other. Developed to create a universal standard, these specifications define the messages, commands, and protocols that allow devices from different manufacturers to work together seamlessly. The MIDI Association maintains and publishes these specifications, ensuring compatibility and innovation across the music technology industry. From basic note-on/note-off messages to advanced control protocols like MIDI 2.0, the specifications cover a wide range of use cases—from performance and production to lighting and automation. Understanding MIDI specifications is crucial for developers, musicians, and engineers who aim to integrate or build MIDI-compatible tools and systems in today’s interconnected musical ecosystem.
