title: How to detect simultaneous onPress events in react native?
body: <p>I'm trying to set a react native app that plays sounds when the user touches buttons.  This works fine when touching one button at a time. </p>
  
  <p>However, it appears that only one <code>onPressIn</code> function can run at once.  But I want to be able to press multiple buttons simultaneously.  This is for cases where you might want to hold a long note and then play a rapid percussion sound over it.</p>
  
  <p>My components look like: </p>
  
  <pre><code>&lt;TouchableHighlight onPressIn={this.padPress.bind(this, padNum)} underlayColor="gray"&gt;
    &lt;View style={[padWidth]}&gt;&lt;/View&gt;
  &lt;/TouchableHighlight&gt;
  </code></pre>
  
  <p>Is there a way to detect multiple button pushes at once?  Or another way to achieve this functionality?  </p>
  
  <p>Thanks!</p>
