Indeed, mapping dashboards on the clip level can only be done for the selected clip easily.
If you want to map the same dial on your controller to a dashboard dial in every clip, then you need to do it for every clip currently.
Are you using the same effect mapped to the dashboard on these clips?
Maybe using an Effect clip
, or layer effects would work.
And...you can assign shortcut groups to a MIDI knob but not a dashboard one, why?
Could you give an example what you'd like to do exactly?
