// Generate a MIDI file that plays one note from all 128 GM instruments (in
// order), followed by all the percussion notes.
//
// When this file is played through an OPL synthesiser capable of MIDI
// playback, then captured through DOSBox, it will provide a complete set of
// OPL patches that can easily be associated back to MIDI instruments.
