A simple example of how to use it:

from MidiOutFile import MidiOutFile

    out_file = 'song.mid'
    midi = MidiOutFile(out_file)
    midi.header()
    midi.start_of_track() 
    midi.update_time(0)
    midi.note_on(channel=0, note=0x40)
    midi.update_time(192)
    midi.note_off(channel=0, note=0x40)
    midi.update_time(0)
    midi.end_of_track()
    midi.eof()
