    MIDI File Formats
    MIDI files come in 3 variations:

    Format 0
    ...which contain a single track

    Format 1
    ... which contain one or more simultaneous tracks
    (ie all tracks are to be played simultaneously).

    Format 2
    ...which contain one or more independant tracks
    (ie each track is to be played independantly of the others).

    Format 0 MIDI Files
    Format 0 MIDI files consist of a header-chunk and a single track-chunk.

    The single track chunk will contain all the note and tempo information.

    Format 1 MIDI Files
    Format 1 MIDI files consist of a header-chunk and one or more track-chunks, with all tracks being played simultaneously.

    The first track of a Format 1 file is special, and is also known as the 'Tempo Map'. It should contain all meta-events of the types Time Signature, and Set Tempo. The meta-events Sequence/Track Name, Sequence Number, Marker, and SMTPE Offset. should also be on the first track of a Format 1 file.

    Format 2 MIDI Files
    Format 2 MIDI files consist of a header-chunk and one or more track-chunks, where each track represents an independant sequence.

    Hope this helps

    My experience? In format 1 each voice is saved in its own track.... format 1 condenses the voices to one track. I don't know why though. I much prefer format 0 and its what you'll find the most of on this board :)
