<h2>Syntax</h2>
<pre class="synopsis"><span class="command"><strong>dssictls</strong></span> ihandle, iport, kvalue, ktrigger </pre>
</div>
<div class="refsect1">
<a id="idm281472940602664"></a>
<h2>Description</h2>
<p><span class="emphasis"><em>dssictls</em></span> sends control values to a plugin's control port</p>
</div>
<div class="refsect1">
<a id="idm281472940601128"></a>
<h2>Initialization</h2>
<p>
<span class="emphasis"><em>ihandle</em></span> - handle for the plugin returned by <a class="link" href="dssiinit.html" title="dssiinit"><em class="citetitle">dssiinit</em></a>
</p>
<p>
<span class="emphasis"><em>iport</em></span> - control port number
</p>
</div>
<div class="refsect1">
<a id="idm281472940597704"></a>
<h2>Performance</h2>
<p>
<span class="emphasis"><em>kvalue</em></span> - value to be assigned to the port
</p>
<p>
<span class="emphasis"><em>ktrigger</em></span> - determines whether the control information will be sent (ktrigger = 1) or not. This is useful for thinning control information, generating ktrigger with <a class="link" href="metro.html" title="metro"><em class="citetitle">metro</em></a>
</p>
<p>
<span class="emphasis"><em>dssictls</em></span> sends control information to a LADSPA or DSSI plugin's control port. The valid control ports and ranges are given by <a class="link" href="dssiinit.html" title="dssiinit"><em class="citetitle">dssiinit</em></a> . Using values outside the ranges may produce unspecified behaviour.

<h2>Examples</h2>
<p>
Here is an example of the dssictls opcode. It uses the file <a class="ulink" href="examples/dssictls.csd" target="_top"><em class="citetitle">dssictls.csd</em></a>.
