<h2>Description</h2>
<p>Collects all audio from all Fluidsynth engines in a performance
</p>
</div>
<div class="refsect1" title="Performance">
<a id="idp23031096"></a>
<h2>Performance</h2>
<p><span class="emphasis"><em>aleft</em></span> -- Left channel audio output.</p>
<p><span class="emphasis"><em>aright</em></span> -- Right channel audio output.</p>
<p>Invoke fluidAllOut in an instrument definition numbered higher than
any fluidcontrol instrument definitions. All SoundFonts send their
audio output to this one opcode. Send a note with an indefinite duration to
this instrument to turn the SoundFonts on for as long as
required.</p>
<p>In this implementation, SoundFont effects such as chorus or
reverb are used if and only if they are defaults for the preset. There
is no means of turning such effects on or off, or of changing their
parameters, from Csound.</p>
