the class MixerNode method getMixerCode.

/**

 * will make it to the Master output or not, checking both down graph of
 * output channels as well as sends for each channel. If not, does not
 * generate output for Send. </li>

 * <li> if channel does not have channel output and no valid prefader sends,
 * do not generate anything </li>
