It can happen that some parameter of a card module cannot be controlled anymore.  For example routing of video signals cannot be changed suddenly.

This leads to no control of some parameters.

If the card has User Presets it is likely that a GPI influence is set as shown here:

Therefore a warning sign appears in the Main view:


Some parameters are locked then. And can only be changed if GPI influence is set to "none".

This affects all cards with GPI settings and UserPreset.
