+ <dfn>Insert return(s)</dfn>, both of which are either audio device or JACK ports.
+ While jack ports are visible to other JACK applications, ALSA ports are only
+ useful for patching in audio equipment external to the computer. If inserting
+ a software processor is required, a plugin would be the first choice. If a plugin
+ is not available then the jackd audio backend would have to be used. This is
+ not very common any more but there are some older jack clients that require
+ using jack.<br>
+ Inserts work the same as the inserts on analog consoles except they are not
+ normalled like most jacks on an analog console.
