Changing the name of AudioProcessor parameters during lifetime

Audio Plugins

May I suggest the following tiny modification:

In file juce_AU_Wrapper.mm, 

Replacing:

void audioProcessorChanged (AudioProcessor*)
{
    PropertyChanged (kAudioUnitProperty_Latency, kAudioUnitScope_Global, 0);
}

with :

void audioProcessorChanged (AudioProcessor*) override
{
    PropertyChanged (kAudioUnitProperty_Latency, kAudioUnitScope_Global, 0);
        
    PropertyChanged (kAudioUnitProperty_ParameterList, kAudioUnitScope_Global, 0);
        
    PropertyChanged (kAudioUnitProperty_ParameterInfo, kAudioUnitScope_Global, 0);
}

 

This would allow to change the name of the parameters during the lifetime of the AudioProcessor (by calling AudioProcessor::updateHostDisplay), which might be useful on some (rare) occasions.

Or maybe there is a better way to do that ?

 

NB : It seems that dynamically changing the name of the parameters already works fine in VST and AAX (at least in the few hosts I tested).

Thanks for the tip - sounds sensible, I'll have a look!
