<title>Initialization</title>
<para>
<emphasis>icnt</emphasis> -- maximum number of phasors to be used.
</para>
<para>
<emphasis>iphs</emphasis> -- initial phase, expressed as a fraction of a cycle (0 to 1). If -1 initialization is skipped. If <emphasis>iphas</emphasis>>1 each phasor will be initialized with a random value.
</para>
</refsect1>
<refsect1>
<title>Performance</title>
<para>
<emphasis>kndx</emphasis> -- index value to access individual phasors
</para>
<para>
For each independent phasor, an internal phase is successively accumulated in accordance with the <emphasis>kcps</emphasis> or <emphasis>xcps</emphasis> frequency to produce a moving phase value, normalized to lie in the range 0 <= phs < 1. Each individual phasor is accessed by index <emphasis>kndx</emphasis>.
</para>
<para>
This phasor bank can be used inside a k-rate loop to generate multiple independent voices, or together with the <emphasis>adsynt</emphasis> opcode to change parameters in the tables used by <emphasis>adsynt</emphasis>.
</para>

<title>Examples</title>
<para>
Here is an example of the phasorbnk opcode. It uses the file <ulink url="examples/phasorbnk.csd"><citetitle>phasorbnk.csd</citetitle></ulink>.

</example>
Generate multiple voices with independent partials. This example is better with <emphasis>adsynt</emphasis>. See also the example under <link linkend="adsynt"><citetitle>adsynt</citetitle></link>, for k-rate use of <emphasis>phasorbnk</emphasis>.
