// insert buffer
let player = new MidiPlayer(midi);

    event; // information of event
    portnum; // port number. I put it in advance to support the port prefix meta event
    message; // midi message. if it is null, this event is meta event
});

player.play();
player.pause();

player.tempo; // similar to HTMLMediaElement.playbackRate
player.durationTick; // same as MidiFile.header.durationTick

player.currentTick;
player.currentMs;

let buf2 = fs.readFileSync('....'); // another midi file
