        <h2>Performance</h2>
        <p>
Use of the mixer requires that instruments setting gains have smaller numbers than instruments sending signals, 
and that instruments sending signals have smaller numbers than instruments receiving those signals. 
However, an instrument may have any number of sends or receives. After the final signal is received, 
<a class="link" href="MixerClear.html" title="MixerClear"><em class="citetitle">MixerClear</em></a> must be invoked to reset the busses to 0 before the next kperiod.
