The host might decide to use "cloned" (slave) instances in various scenarios, e.g. to process
audio paths with different latencies simultaneously or to synchronize grouped plug-in instances
between multiple mixer channels - see SlaveMode. In this case multiple plug-in instances are active
at the same time even though it looks like one to the user, i.e. only the editor of the master
instance is visible and can be used to change parameters. The edit controller implementation has
to synchronize parameter changes between instances that aren't visible to the host internally.
