thumb|Example of music created in MIDI format thumb|alt=Several rack-mounted synthesizers that share a single controller|Using MIDI, a single controller (often a musical keyboard, as pictured here) can play multiple electronic instruments, which increases the portability and flexibility of stage setups. This system fits into a single rack case, but before MIDI, it would have required four separate full-size keyboard instruments, plus outboard mixing and effects units.

AI overview

MIDI is a standard protocol that allows electronic musical instruments and computers to communicate and control each other. It enables a single controller, like a keyboard, to play multiple instruments simultaneously, making music setups more portable and flexible than having separate instruments for each sound.
