<h2>Syntax</h2>
<pre class="synopsis"><span class="command"><strong>moscil</strong></span> kchn, knum, kvel, kdur, kpause</pre>
</div>
<div class="refsect1" title="Performance">
<a id="idp32280032"></a>
<h2>Performance</h2>
<p>
<span class="emphasis"><em>kchn</em></span> -- MIDI channel number (1-16)
</p>
<p>
<span class="emphasis"><em>knum</em></span> -- note number (0-127)
</p>
<p>
<span class="emphasis"><em>kvel</em></span> -- velocity (0-127)
</p>
<p>
<span class="emphasis"><em>kdur</em></span> -- note duration in seconds
</p>
<p>
<span class="emphasis"><em>kpause</em></span> -- pause duration after each noteoff and before new note in seconds
</p>
<p>
<span class="emphasis"><em>moscil</em></span> and <a class="link" href="midion.html" title="midion"><em class="citetitle">midion</em></a> are the most powerful MIDI OUT opcodes. <span class="emphasis"><em>moscil</em></span> (MIDI oscil) plays a stream of notes of <span class="emphasis"><em>kdur</em></span> duration. Channel, pitch, velocity, duration and pause can be controlled at k-rate, allowing very complex algorithmically generated melodic lines. When current instrument is deactivated, the note played by current instance of <span class="emphasis"><em>moscil</em></span> is forcedly truncated.
</p>
<p>
Any number of <span class="emphasis"><em>moscil</em></span> opcodes can appear in the same Csound instrument, allowing a counterpoint-style polyphony within a single instrument.
</p>

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

<p>This example generates a stream of notes for every note received on the MIDI input. It generates MIDI notes on csound's MIDI output, so be sure to connect something.</p>
