electronic musical instrument industry specification / From Wikipedia, the free encyclopedia

A MIDI recording is not an audio signal. It is more like a piano roll, identifying the pitch, start and stop time and other properties of each individual note.[2]
The personal computer market stabilized at the same time,[3][4] popularizing the MIDI format, and helped computers become a viable option for music production.[5]
