Hi Cubace,
Are you using MCU, or any other hardward controller in Mackie mode?
If I am not mistaken, the Page 0 that you are referring to is the top layer that contains the plugin name and the bypass parameter, am I correct? If this is what you mean, then I can confirm that this “Page 0” is not editable and is defined by the Mackie HW standard. It serves as the “Home” page or default header on top of your defined layout. Hope this info helps!
