var saw = context.createOscillator(),
      sine = context.createOscillator(),
      sineGain = context.createGainNode();

//set up our oscillator types
saw.type = saw.SAWTOOTH;
sine.type = sine.SINE;

//set the amplitude of the modulation
sineGain.gain.value = 10;

//connect the dots
sine.connect(sineGain);
sineGain.connect(saw.frequency);
