What is a .MID file?

MIDI stores musical note and instrument instructions rather than recorded audio, so any synthesiser can play it back.

Did you know
  • The MIDI standard was agreed by rival synthesiser makers in 1983 and is still how electronic instruments talk to each other.
  • A Standard MIDI File is built from chunks: a single header chunk followed by one or more track chunks holding the timed events.
  • A single MIDI link carries up to sixteen separate channels, each able to drive a different instrument or device.
  • On the web a .MID file is served with the MIME type audio/midi.
  • Analyser spots a .MID file by its signature bytes 4D 54 68 64 - ASCII for "MThd".
