    /***************************************************************
     * TSE3 example MIDI file program
     * ==============================
     *
     * This example contains four "steps"
     *
     *   1. We use a MidiFile object to access a standard MIDI file.
     *   2. We create a Transport object to play it with
     *   3. We create a Song object from the data in the MIDI file
     *      and play it.
     *   4. Creating a Song takes some time (well, not too much really).
     *      If you don't need to manipulate the data in the MIDI file,
     *      just play it, this shows a slightly quicker way.
     *
