</h2>
<p>oscilikts —
A linearly interpolated oscillator with sync status that allows changing the table number at k-rate.
</p>
</div>
<div class="refsect1">
<a id="idm281472908794184"></a>
<h2>Description</h2>
<p>
<span class="emphasis"><em>oscilikts</em></span> is the same as <a class="link" href="oscilikt.html" title="oscilikt"><em class="citetitle">oscilikt</em></a>. Except it has a sync input that can be used to re-initialize the oscillator to a k-rate phase value. It is slower than <a class="link" href="oscilikt.html" title="oscilikt"><em class="citetitle">oscilikt</em></a> and <a class="link" href="osciliktp.html" title="osciliktp"><em class="citetitle">osciliktp</em></a>.
</p>
</div>
<div class="refsect1">
<a id="idm281472908719096"></a>
<h2>Syntax</h2>
<pre class="synopsis">ares <span class="command"><strong>oscilikts</strong></span> xamp, xcps, kfn, async, kphs [, istor]</pre>
</div>
<div class="refsect1">
<a id="idm281472908716840"></a>
<h2>Initialization</h2>
<p>
<span class="emphasis"><em>istor</em></span> (optional, defaults to 0) -- skip initialization.
</p>
</div>
<div class="refsect1">
<a id="idm281472908715080"></a>
<h2>Performance</h2>
<p>
<span class="emphasis"><em>xamp</em></span> -- amplitude.
</p>
<p>
<span class="emphasis"><em>xcps</em></span> -- frequency in Hz. Zero and negative values are allowed. However, the absolute value must be less than <a class="link" href="sr.html" title="sr"><em class="citetitle">sr</em></a> (and recommended to be less than <span class="emphasis"><em>sr/</em></span>2).
</p>
<p>
<span class="emphasis"><em>kfn</em></span> -- function table number. Can be varied at control rate (useful to <span class="quote">“<span class="quote">morph</span>”</span> waveforms, or select from a set of band-limited tables generated by <a class="link" href="GEN30.html" title="GEN30"><em class="citetitle">GEN30</em></a>).
</p>
<p>
<span class="emphasis"><em>async</em></span> -- any positive value resets the phase of <span class="emphasis"><em>oscilikts</em></span> to <span class="emphasis"><em>kphs</em></span>. Zero or negative values have no effect.
</p>
<p>
<span class="emphasis"><em>kphs</em></span> -- sets the phase, initially and when it is re-initialized with async.
</p>

<h2>Examples</h2>
<p>
Here is an example of the oscilikts opcode. It uses the file <a class="ulink" href="examples/oscilikts.csd" target="_top"><em class="citetitle">oscilikts.csd</em></a>.
