MIDI, which stands for Musical Instrument Digital Interface, is a technical standard that allows electronic musical instruments, computers, and other devices to communicate with each other. It transmits information about music performance, such as notes played, their duration, and intensity, rather than actual audio signals. This enables musicians to control multiple instruments and software from a single device. Since its introduction in the early 1980s, MIDI has become a fundamental tool in music production and performance. It allows for easy editing and manipulation of musical compositions, making it popular among composers, producers, and performers. With MIDI, users can create complex arrangements and control various aspects of sound without needing to record live audio.
