<p>fmb3 —
Uses FM synthesis to create a Hammond B3 organ sound.
</p>
</div>
<div class="refsect1">
<a id="idm281472930995592"></a>
<h2>Description</h2>
<p>
Uses FM synthesis to create a Hammond B3 organ sound. It comes from a family of FM sounds, all using 4 basic oscillators and various architectures, as used in the TX81Z synthesizer.

<h2>Syntax</h2>
<pre class="synopsis">ares <span class="command"><strong>fmb3</strong></span> kamp, kfreq, kc1, kc2, kvdepth, kvrate[, ifn1, ifn2, ifn3, \
ifn4, ivfn]</pre>

<div class="refsect1">
<a id="idm281472930932568"></a>
<h2>Initialization</h2>
<p>
<span class="emphasis"><em>fmb3</em></span> takes 5 tables for initialization. The
first 4 are the basic inputs and the last is the low frequency
oscillator (LFO) used for vibrato. The last table should usually
be a sine wave. These all default to a sine wave table.
</p>
<p>
The initial waves should be:
