+1 – I think this would greatly expand the capabilities of the AuxSwitches.

I can see the usefulness of the Global Min and Max, if the same knob always controlled the same function, but they don't always. For instance, in Space, the Xnob controls LoDecay in the Hall algorithm, Early Reflections in the Room algorithm, Distance in Plate, Tremolo Intensity in Spring, etc., etc. The same thing applies to several knobs in many algorithms on all the Factors. Being able to set either the MIN VAL (as Har suggests) or the MAX VAL to the value stored in the preset would give us some control on a preset-to-preset basis of what the AuxSw would do.

Great idea, Har! And thanks, Nick, for adding this to the list of things you'll be considering for future revisions!
