+<div class="classdox"><p class="para-brief"> A stub Processor that can be used in place of a `real' one that cannot be created for some reason; usually because it requires a plugin which is not present. UnknownProcessors are special-cased in a few places, notably in route configuration and signal processing, so that on encountering them configuration or processing stops.</p><p> When a Processor is missing from a Route, the following processors cannot be configured, as the missing Processor's output port configuration is unknown.</p><p> The main utility of the UnknownProcessor is that it allows state to be preserved, so that, for example, loading and re-saving a session on a machine without a particular plugin will not corrupt the session.</p></div>
