<p>pgmassign —
Assigns an instrument number to a specified MIDI program.
</p>
</div>
<div class="refsect1" title="Description">
<a id="idp36035056"></a>
<h2>Description</h2>
<p>
Assigns an instrument number to a specified (or all) MIDI program(s).
</p>
<p>
By default, the instrument is the same as the program number. If the selected instrument is zero or negative or does not exist, the program change is ignored. This opcode is normally used in the orchestra header. Although, like <a class="link" href="massign.html" title="massign"><em class="citetitle">massign</em></a>, it also works in instruments.

<h2>Syntax</h2>
<pre class="synopsis"><span class="command"><strong>pgmassign</strong></span> ipgm, inst[, ichn]</pre>
<pre class="synopsis"><span class="command"><strong>pgmassign</strong></span> ipgm, "insname"[, ichn]</pre>
</div>
<div class="refsect1" title="Initialization">
<a id="idp36081072"></a>
<h2>Initialization</h2>
<p>
<span class="emphasis"><em>ipgm</em></span> -- MIDI program number (1 to 128). A value of zero selects all programs.
</p>
<p>
<span class="emphasis"><em>inst</em></span> -- instrument number. If set to zero, or negative, MIDI program changes to <span class="emphasis"><em>ipgm</em></span> are ignored. Currently, assignment to an instrument that does not exist has the same effect. This may be changed in a later release to print an error message.
</p>
<p>
<span class="emphasis"><em><span class="quote">“<span class="quote">insname</span>”</span></em></span> -- A string (in double-quotes) representing a named instrument.
</p>
<p>
<span class="emphasis"><em><span class="quote">“<span class="quote">ichn</span>”</span></em></span> (optional, defaults to zero) -- channel number. If zero, program changes are assigned on all channels.
</p>
<p>
You can disable the turning on of any instruments by using the following in the header:
