<h2>Performance</h2>
<p>
<span class="emphasis"><em>kiter</em></span> - number of iterations
</p>
<p>
<span class="emphasis"><em>koutrig</em></span> - output trigger signal
</p>
<p>
<span class="emphasis"><em>ktrig</em></span> - input trigger signal
</p>
<p>
<span class="emphasis"><em>kx, ky</em></span> - coordinates of a given point belonging to the complex plane
</p>
<p>
<span class="emphasis"><em>kmaxIter</em></span> - maximum iterations allowed
</p>
<p>
<span class="emphasis"><em>mandel</em></span> is an opcode that allows the use of the Mandelbrot set formula to generate an output that can be applied to any musical (or non-musical) parameter. It has two output arguments: <span class="emphasis"><em>kiter</em></span>, that contains the iteration number of a given point, and <span class="emphasis"><em>koutrig</em></span>, that generates a trigger 'bang' each time <span class="emphasis"><em>kiter</em></span> changes. A new number of iterations is evaluated only when <span class="emphasis"><em>ktrig</em></span> is set to a non-zero value. The coordinates of the complex plane are set in <span class="emphasis"><em>kx</em></span> and <span class="emphasis"><em>ky</em></span>, while <span class="emphasis"><em>kmaxIter</em></span> contains the maximum number of iterations. Output values, which are integer numbers, can be mapped in any sorts of ways by the composer.
