It would be helpful if you could be a bit more specific about what the
registers look like and what the problems you are encountering are.
Since what you're saying is so generic and non-specific it's hard to
really say anything concrete. Possibly what you want to do is have an
event on the widgets for the mixers which does the appropriate setup?

The easiest thing is to look at the git logs and see how similar things
were added then do the equivalent thing. That'll show all the areas
that need updating.
