OK. With my version it works without problems with your file. That should be solved. Which Ikarus version do you use?
Backup your changes. Not that to be overwritten.
Regnad517, I think there is a misunderstanding here. After redefining the instrument, you must also re-enter the instrument functions. For this you mark the instrument and then switch to the tab "Instrumentfunctions". Did you try that?
Gray shadow? If you mean the gray background, I have already made darker. You need Photoshop or something like that. In the folder "Background" you will find the file "F5E_FrontPanelDark.PNG".
Yes, I've thought about that before. But how often do you really bump that? That's why I've put that back at the moment. If I look back, I might have missed it 3 times. It works without it.
