Look to code of original example.

You changed it.
You created endless loop that sends to the player millions notes per second.

Change it back. You need to send notes for next time piece only.

Original function. Look to 'setInterval'

function start() {
  if (started) {
	  console.log('started already');
  } else {
	  started = true;
	  startTime = audioContext.currentTime + 0.1;
	  nextPiece();
	  startTime = startTime + pieceLen;
	  setInterval(function () {
		  if (audioContext.currentTime > startTime - 1 / 4 * N) {
			  nextPiece();
			  startTime = startTime + pieceLen;
		  }
	  }, 20);
  }
}

I see scheduling is too hard task.
I added new class for scheduling, look to WebAudioFontTicker at

Nice. Would be handy to have the ticker functions on the wiki.
