Which thread calls AudioProcessorParameter::setValue?

Thanks, noted. I still don’t know where to start for updating controls from host automation though. Can you point me somewhere to look? I’ve read the reference many times and I still don’t get it. The only thing I can think of is setting a flag when a GUI control is changed to avoid it updating itself… It looks a lot like I’m missing something.

EDIT: I think this answers it, if it’s still up-to-date.
