= MIDI
{c}
{wiki}
In simple terms, represents keystrokes of a piano, but it can likely also represent other effects (TODO confirm: bend, vibrato, slides, attack strength)
Can contain multiple parallel tracks as seen from the <Wikipedia> example: https://en.wikipedia.org/wiki/File:MIDI_sample.mid
You can see what it contains well with <GUI music editor>.
MIDI is fun. It is a basic high level representation of most instrumental music, including beats.
To actually listen to MIDI, you need a <software synthesizer>, which knows what sound to make for each note. One way to specify such instruments is the <SoundFont> file format.
