Thank you! Now I'm wondering is there a way to use the Aux Switch to increase the mix to 100, but upon another click it would decrease it to the preset's saved mix level?
Some algorithms have a HotSwitch which allows you to toggle between two sets of preset values. An aux switch can be used to control that, but not every algorithm has that function. The HotSwitch could be used to do what you're describing though. It's available in all of the reverb (Space) algorithms as well as the algorithms that were developed for the H9.
