<p>STK moog-like swept filter sampling synthesis class. </p>
<p>This instrument uses one attack wave, one looped wave, and an <a class="el" href="classstk_1_1ADSR.html" title="STK ADSR envelope class.">ADSR</a> envelope (inherited from the <a class="el" href="classstk_1_1Sampler.html" title="STK sampling synthesis abstract base class.">Sampler</a> class) and adds two sweepable formant (<a class="el" href="classstk_1_1FormSwep.html" title="STK sweepable formant filter class.">FormSwep</a>) filters.</p>
<p>Control Change Numbers:</p>
<ul>
<li><a class="el" href="classstk_1_1Filter.html" title="STK abstract filter class.">Filter</a> Q = 2</li>
<li><a class="el" href="classstk_1_1Filter.html" title="STK abstract filter class.">Filter</a> Sweep Rate = 4</li>
<li>Vibrato Frequency = 11</li>
<li>Vibrato Gain = 1</li>
<li>Gain = 128</li>
