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".
