Really nice to read you're enjoying D4 as much
Sadly, if you want to change your lights, chances are you're going to lose most of your settings
The reason for this is that the DMX levels you set in your scenes are specifically set for your fixtures
, as they are now. If you delete the fixtures and add new ones, the values won't fit your new fixtures and you will need to adapt your scenes
to the new fixtures.
Hope I could explain this in a clear way.
