1) In MIDI file integer are stored in straigth order as opposed to the
inverted order used in PC. bytes_to_int() suppose that the first byte is the
least significant (INTEL style) in MIDI file the first byte is most
significant (MOTOROLA style), so bytes_to_int() will give a wrong result if
you use it to read MIDI file.
