<p>pvsin —
Retrieve an fsig from the input software bus; a pvs equivalent to chani.

<div class="refsect1" title="Description">
<a id="idp39007416"></a>
<h2>Description</h2>
<p>
This opcode retrieves an f-sig from the pvs in software bus, which can be
used to get data from an external source, using the Csound 5 API. A channel
is created if not already existing. The fsig channel is in that case initialised with
the given parameters. It is important to note that the pvs input
and output (pvsout opcode) busses are independent and data is not shared between them.
