If an LV2 plugin has an internal state and that state changes, a host is
non the wiser. The host cannot mark the session as dirty (modified,
e.g. Save the session or plugin-preset (marked "clean") then load a new
sample into a synth (using a custom plugin GUI). On the outside nothing
changes. Now close the session, quit the host: The changes are lost
(same for presets or any state that needs saving).
I propose http://lv2plug.in/ns/ext/state/#Dirty which allows a plugin
that has a state interface to notify the host about state changes using
an Atom message:
a rdfs:Class ;
rdfs:label "State modified message" .
Thoughts? Comments are welcome.
