title: Audiokit: EZMicrophone + AKOscillator AKMixer
body: <p>I'm using Audio Kit to see it will make life easier... and here's my problem:
  I'm using EZ Microphone because it gives me a nice buffer that I can stick in a circular queue and analyze. </p>
  
  <p>That works fine until I also start up some oscillators and plug them into the mixer, and make that output the AudioKit.output. Then, I can get my beeps, but the Mic stops feeding me data (with no notification, BTW).
  It works fine in the simulator, just not on the device. </p>
  
  <p>I might be able to use AKMicrophone and tap its output, but it's not as nice as getting a block that I can just shovel into the circular queue .</p>
  
  <p>Advice?</p>
