title: How to change from one musicSequence to another without time delay
body: <p>I'm playing a MIDI sequence via <code>MusicPlayer</code> which I loaded from a MIDI file and I want to change the sequence to another while playback. 
  When I try this:</p>
  
  <pre><code> MusicPlayerSetSequence(_player, sequence);
   MusicSequenceSetAUGraph(sequence, _processingGraph);
  </code></pre>
  
  <p>it stops the playback. So I start it back again and set the time with</p>
  
  <pre><code>MusicPlayerSetTime(_player, currentTime);
  </code></pre>
  
  <p>so it plays again where the previous sequence stopped, but there is a little delay.
  I've tried to add the time interval to <code>currentTime</code>, which I got by obtaining the time before stopping and after starting again. But there is still a delay.</p>
  
  <p>I was wondering if there is an alternative to stopping -> changing sequence -> starting again.</p>
