<h2><a class='anchor' name='description'>Description</a></h2>
<p>A two-channel reverb <a href="./../Classes/UGen.html">UGen</a>, based on the "GVerb" LADSPA effect by Juhana Sadeharju (kouhia at nic.funet.fi).<h3><a class='anchor' name='Known%20issues'>Known issues</a></h3>
<ul>
<li>There is a large CPU spike when the synth is instantiated while all the delay lines are zeroed out.<li>Quick changes in roomsize result in zipper noise.<li><em>Changing the roomsize does not work properly! Still trying to look for the bug... (-josh)</em></ul>
