Button Super controls can only do what button Super controls do. When they’re controlling a button, they merely flip it on and off, and when they’re changing a knob, unless they are momentary, they just change it from a low value to a high value.
It is not possible to have a preset for groups exclude certain control from changing. They are all recorded if they are subs of the preset for groups, and they all must change when the preset for groups changes. Obviously, more flexibility would be great, but the you ask for explaining that flexibility to the users, and making it work, makes it a really hard thing to do. We think we’ve hit the sweet spot, but if not, you’re super powered alternative might be lemur. However, that’s a whole new world of debugging that you might not want to get into. Many of our users who have left MIDI Designer to try to work with lemur have ultimately come back. Yes, you give up flexibility, but the thing works.
