Here is the panel.
Yes, it seems some modulators aren’t initialized. Every modulator has a LUA method assigned. If I log to file, I can see in the log the execution of methods of half the modulators of the panel (until modulator with vstindex 303). The other half don’t execute it’s LUA methods never and they don’t store it’s value on save (move the sliders, save the panel and reopen it. The modulators are again -1).
