I have a similar question regarding how to display feedback from a read only parameter.
My controller inherits from VSTGUI::VST3EditorDelegate, similar to the again and helloworldWithVSTGUI samples.
I am using the WYSIWIG editor with an XML file, and have set the control tag to the corresponding VST3 parameter, after syncing the parameter tags.
In debugging mode, the host provides my editor with callbacks to the setParamNormalized() method, but I am not seeing the value updated in the VSTGUI.
I have tried using VU Meter and Text Label objects within the WYSIWYG editor.
