<p>connect —
Connects a source outlet to a sink inlet.
</p>
</div>
<div class="refsect1" title="Description">
<a id="idp16311944"></a>
<h2>Description</h2>
<p>
The connect opcode, valid only in the orchestra header, sends the signals
from the indicated outlet in all instances of the indicated source
instrument to the indicated inlet in all instances of the indicated sink
instrument. Each inlet instance receives the sum of the signals in all
outlet instances. Thus multiple instances of an outlet may fan in to one
instance of an inlet, or one instance of an outlet may fan out to
multiple instances of an inlet.
</p>
<p>
When Csound creates a new instance of an instrument template, new instances
of its connections also are created.
