MIDI (Musical Instrument Digital Interface) is a binary encoding of musical "events" (e.g., as note beginning or end) originally designed for communication between electronic musical instruments and devices (e.g., keyboards, synthesizers, etc.) Since MIDI events contain a time stamp, streams could be saved as files and processed by computers. (MIDI Files are listed in the Arts/Music/Sound Files/MIDI category.) This category contains sites that contain, describe, or sell software related to MIDI file creation, editing, or usage.
