I think I may have a work-around…
I derived my PluginWindow class from AudioProcessorListener and added it as a Listener to the 3rd party plug-in’s AudioProcessor. When PluginWindow receives audioProcessorChanged() it triggers an AsyncUpdate to the AudioProcessorGraph which causes it to buildRenderingSequence(). It appears to be working okay.
I added a public method to AudioProcessorGraph:
void refreshGraph() { triggerAsyncUpdate(); }I would prefer that I only could get a notification when the AudioProcessor latency changes though.
