* Example: Mixing a webcam with gif or video

var renderer = new GlRenderer();
var video1 = new VideoSource( renderer, { src: ''} )
var gif1 = new GifSource( renderer, { src: ''} )
var mixer1 = new Mixer( renderer, { source1: gif1, source2: video1 });
var output = new Output( renderer, mixer1 )

var tapped_bpm = new BPM( renderer )
var keyboard1 = new KeyboardController( renderer )


// there are two ways to do this
// first set a bpm (default is 128)
tapped_bpm.bpm = 128

// 1) add the bpm to the mixer
// this way you can assign several mixers to the same bpm
tapped_bpm.add( mixer1.pod )

// 2) or bind the bpm to the mixer' internal bpm
// this allows you to control each mixers internal bpm individually
// mixer1.autoFade = true
// mixer1.bindBpm( tapped_bpm.getBpm ) 

// press enter for tap
keyboard1.addEventListener( 13, function(arr) { 
  if (arr[1] == 1) {
