smfplayer.js

============

smfplayer.js は [WebMidiLink](http://www.g200kg.com/en/docs/webmidilink/) 対応シンセサイザを用いた標準 MIDI ファイルプレイヤーです。

## 使い方

```js

var player = new SMF.Player();

window.addEventListener('DOMContentLoaded', function() {

  /** @type {boolean} */

  var loop = true;

  /** @type {boolean} */

  var cc111 = true;

  /** @type {boolean} */

  var falcom = true;

  /** @type {boolean} */

  var mfi = true;

  /** @type {number} */

  var tempo = 1.0;

  /** @type {number} 0-16383 */

  var volume = 16383 * 0.5;

  // player settings

  player.setLoop(loop); // Player Loop

  player.setCC111Loop(cc111); // CC#111 Loop

  player.setFalcomLoop(falcom); // Ys2 Eternal Loop

  player.setMFiLoop(mfi); // MFi Loop

  player.setTempoRate(tempo); // Playback tempo rate

  player.setMasterVolume(volume); // Master Volume

  player.setWebMidiLink('http://www.g200kg.com/en/docs/gmplayer/');

  // load standard MIDI file

  loadSMF('hoge.mid');

}, false);

/**

 * @param {string} url

 */

function loadSMF(url) {

  var xhr = new XMLHttpRequest();

  xhr.open('GET', url, true);

  xhr.addEventListener('load', function (event) {

    /** @type {Uint8Array} */

    var input = new Uint8Array(event.target.response);

    // load MIDI file

    player.loadMidiFile(input);

    player.play();

  }, false);

  xhr.responseType = 'arraybuffer';

  xhr.send();

}

```
