说明：  Midi format 0 contains only one track. Midi format 1 contains a tempo track and one or more singlechannel tracks that should be played together. Midi format 1 files are easier to modify (e.g. with MIDI2TXT/TXT2MIDI) because the channel jumping operator [##] is not needed. Midi format 1 files are printed using MIDI2TXT as MTrk($A) ... end Mtrk Use MIDI2TXT -i to show the version of midi file.
