i googled around and couldn't find any indication on whether or not AU

given that ardour does automation from the RT/audio thread, it seems
unlikely to me that we want to be notifying listeners (e.g. plugin
GUIs) of changes from there. i find it unlikely that most plugins
defer the real handling of a property notification to a non-RT thread.
am i right?
Nope.
AUEventListener provides a means to do safe real-time thread property
change listening - for some years now we've been advocating people use
this. It is the same mechanism we use for parameter notifications.

Why not just ask if this is supported, instead of first asserting that
we (again) haven't thought about something?
thanks,
