<h2>Warning</h2>
<p>
<span class="emphasis"><em>midictrl</em></span> should only be used in notes that were triggered from MIDI, so that an associated channel number is available. For notes activated from the score, line events, or orchestra, the <a class="link" href="ctrl7.html" title="ctrl7"><em class="citetitle">ctrl7</em></a> opcode that takes an explicit channel number should be used instead.

<h2>Examples</h2>

Here is an example of the midictrl opcode. It uses the file <a class="ulink" href="examples/midictrl.csd" target="_top"><em class="citetitle">midictrl.csd</em></a>
