<h2>Description</h2>
<p>
Limits the number of allocations of an instrument.

<h2>Syntax</h2>
<pre class="synopsis"><span class="command"><strong>maxalloc</strong></span> insnum, icount</pre>
<pre class="synopsis"><span class="command"><strong>maxalloc</strong></span> Sinsname, icount</pre>
</div>
<div class="refsect1">
<a id="idm281472915895672"></a>
<h2>Initialization</h2>
<p>
<span class="emphasis"><em>insnum</em></span> -- instrument number
</p>
<p>
<span class="emphasis"><em>Sinsname</em></span> -- instrument name
</p>
<p>
<span class="emphasis"><em>icount</em></span> -- number of instrument allocations

<div class="refsect1">
<a id="idm281472915892184"></a>
<h2>Performance</h2>
<p>
<span class="emphasis"><em>maxalloc</em></span> limits the number of simultaneous instances (notes) of an instrument. Any score events after the maximum has been reached, are ignored.
</p>
<p>
All instances of <span class="emphasis"><em>maxalloc</em></span> must be defined in the header section, not in the instrument body.
