<h2>Syntax</h2>
<pre class="synopsis">ares <span class="command"><strong>rspline</strong></span> xrangeMin, xrangeMax, kcpsMin, kcpsMax</pre>
<pre class="synopsis">kres <span class="command"><strong>rspline</strong></span> krangeMin, krangeMax, kcpsMin, kcpsMax</pre>

<h2>Performance</h2>
<p>
<span class="emphasis"><em>kres, ares</em></span> -- Output signal
</p>
<p>
<span class="emphasis"><em>xrangeMin, xrangeMax</em></span> -- Range of values of random-generated points
</p>
<p>
<span class="emphasis"><em>kcpsMin, kcpsMax</em></span> -- Range of point-generation rate. Min and max limits are expressed in cps.
</p>
<p>
<span class="emphasis"><em>rspline</em></span> (random-spline-curve generator) is similar to <a class="link" href="jspline.html" title="jspline"><em class="citetitle">jspline</em></a> but output range is defined by means of two limit values. Also in this case, real output range could be a bit greater of range values, because of interpolating curves beetween each pair of random-points.
</p>
<p>
At present time generated curves are quite smooth when <span class="emphasis"><em>cpsMin</em></span> is not too different from <span class="emphasis"><em>cpsMax</em></span>. When <span class="emphasis"><em>cpsMin-cpsMax</em></span> interval is big, some little discontinuity could occurr, but it should not be a problem, in most cases. Maybe the algorithm will be improved in next versions.
</p>
<p>
These opcodes are often better than <a class="link" href="jitter.html" title="jitter"><em class="citetitle">jitter</em></a> when user wants to <span class="quote">“<span class="quote">naturalize</span>”</span> or <span class="quote">“<span class="quote">analogize</span>”</span> digital sounds. They could be used also in algorithmic composition, to generate smooth random melodic lines when used together with <a class="link" href="samphold.html" title="samphold"><em class="citetitle">samphold</em></a> opcode.
</p>
<p>
Note that the result is quite different from the one obtained by filtering white noise, and they allow the user to obtain a much more precise control.
