1. MIDI (Musical Instrument Digital Interface) was created in 1983 to standardize the exchange of data between electronic musical instruments. It allows electronic musical instruments and computers to communicate and synchronize. 2. MIDI does not produce sound itself, but sends messages about pitch, velocity, and other parameters to MIDI-compatible devices that then generate the sounds. 3. There are many options for MIDI controllers like keyboards, strings, wind and percussion instruments that can be used to input musical data into computers and sequencing software for playback, editing, and recording.
