Thanks. But I don't understand what plugging a switch (momentary?) into the expression pedal socket does. Additionally the expression pedal has a sweeping analog range, how does a momentary switch enable you to choose a variety of values? Also if the purpose of your suggestion is to select a parameter value to be saved with the preset,then why not just turn the knob and save it? In this scenario it seems that I do need to create an additional 4 presets just to be able choose the preset with the parameter value that I want. Please clarify!
