 The processor needs to be able to notify the GUI editor when it changes one or more synth parameters (e.g. when a new preset is selected), so it can update the GUI display. This can be done in any number of ways, but I chose to have the //VanillaJuceAudioProcessor// class also derive from the //juce::ChangeBroadcaster//, and the //VanillaJuceAudioProcessorEditor// inherit from //juce::ChangeListener//. The processor calls its //sendChangeMessage()// function to notify the editor, which results in a call to the editor's //changeListenerCallback()// function. The processor needs to be able to notify the GUI editor when it changes one or more synth parameters (e.g. when a new preset is selected), so it can update the GUI display.

 The code for //SynthVoice::soundParameterChanged()// is not so trivial, but all it really does is re-initialize the currently sounding note so that the sound changes to reflect whatever was changed in the GUI. The code for //SynthVoice::soundParameterChanged()// is not so trivial, but all it really does is re-initialize the currently sounding note so that the sound changes to reflect whatever was changed in the GUI.
