Are you using the very latest develop commit? There was a brief regression in the behaviour of updateHostDisplay when called with no arguments, but I believe this issue is fixed now (i.e. consistent with the old behaviour).
That being said, if you know that only the parameter info needs updating, I’d recommend passing ChangeDetails{}.withParameterInfoChanged (true). This will prevent the wrapper from sending other potentially expensive notifications to the host.
If you find that this isn’t working on the latest develop, please let me know and I’ll investigate.
I have a class that inherits both AudioProcessor and AudioProcessorListener and that causes this error. Is there any chance this double declaration can be fixed? Or should I change my code?
