[Ardour-Users] LV2 plugin state

[Paul Davis]

in LV2, all parameter changes are supposed to be routed via the host. If
this does not happen, then the host cannot automate the plugin from the
plugin's own editor.

so a properly written LV2 (and AudioUnit) plugin notifies the host when its
GUI/editor wants to change a parameter.
