title: Web Audio start and stop oscillator then start it again
body: <p>I am trying to start and stop a sound. And that works. But I can't start the sound up again.</p>
  
  <p>Do i really have to make another oscillator again? This just seems extremely un-intuitive. There must be a better way.</p>
  
  <p>This is all i have that works:</p>
  
  <pre><code>oscillator1.noteOn(0);
  oscillator1.noteOff(0);
  </code></pre>
  
  <p>Calling noteOn again doesnt do anything. Why? Is beyond me.</p>
  
  <p>I also tried setting the volume, or in the context of the Web Audio people, "gain", equal to zero. But for some reason, a gain of zero makes sound. What value of gain would not make any sound?</p>
  
  <p>man, i can't believe how difficult this is :/</p>
