MPEZoneLayout missing notification


I am just wondering why the MPEZoneLayout class does not have a Listener, or at least inherit from ChangeBroadcaster. I need to be notified on zone allocation or pitch bend range changes due to incoming MIDI message in order to reflect changes elsewhere. Am I missing something? Is there another way to detect changes? 




This is a question for Timur, who's away until January - please bump it if he doesn't answer when he's back!
