<p>fini —
Read signals from a file at i-rate.

<a id="idm281472937307944"></a>
<h2>Description</h2>
<p>
Read signals from a file at i-rate.
</p>
</div>
<div class="refsect1">
<a id="idm281472937306696"></a>
<h2>Syntax</h2>
<pre class="synopsis"><span class="command"><strong>fini</strong></span> ifilename, iskipframes, iformat, in1 [, in2] [, in3] [, ...]</pre>
</div>
<div class="refsect1">
<a id="idm281472937264696"></a>
<h2>Initialization</h2>
<p>
<span class="emphasis"><em>ifilename</em></span> -- input file name (can be a string or a handle number generated by <a class="link" href="fiopen.html" title="fiopen"><em class="citetitle">fiopen</em></a>)
</p>
<p>
<span class="emphasis"><em>iskipframes</em></span> -- number of frames to skip at the start (every frame contains a sample of each channel)
</p>
<p>
<span class="emphasis"><em>iformat</em></span> -- a number specifying the input file format. If a header is found, this argument is ignored.
</p>
<div class="itemizedlist">
<ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem">
<p>0 - floating points in text format (loop; see below)</p>
</li>
<li class="listitem">
<p>1 - floating points in text format (no loop; see below)</p>
</li>
<li class="listitem">
<p>2 - 32 bit floating points in binary format (no loop)</p>

</div>
<div class="refsect1">
<a id="idm281472937257352"></a>
<h2>Performance</h2>
<p>
<span class="emphasis"><em>fini</em></span> is the complement of <a class="link" href="fouti.html" title="fouti"><em class="citetitle">fouti</em></a> and <a class="link" href="foutir.html" title="foutir"><em class="citetitle">foutir</em></a>. It reads the values each time the corresponding instrument note is activated. When <span class="emphasis"><em>iformat</em></span> is set to 0 and the end of file is reached, the file pointer is zeroed. This restarts the scan from the beginning. When <span class="emphasis"><em>iformat</em></span> is set to 1 or 2, no looping is enabled and at the end of file the corresponding variables will be filled with zeroes.
</p>

<p>Please note that since this opcode generates its output using input parameters (on the right side of the opcode), these variables must be initialized before use, otherwise a 'used before defined' error will occur. You can use the <a class="link" href="init.html" title="init"><em class="citetitle">init</em></a> opcode for this.</p>
