Here's a screenshot to make the issue clear.

I've testing in Reaper, Mainstage, and Logic. I can't seem to figure this one out. I only need the single parameter so that I have a way to telling the host that the project is dirty and needs to be saved. I have the symbiosis code compiled directly into my project.
If there's another way to set the project as dirty, that would be an acceptable workaround. I would actually prefer to have not editable parameters at all for this project.

Rob
