Awesome! I will give this a shot and report back.Probably... Use an IA Cycle button with actions like this:
Audio / FnSwitch off:OFF on:ON
System / Step
Audio / FnSwitch off:OFF on:ON
System / Step
Audio / FnSwitch off:OFF on:ON
System / Step
Audio / FnSwitch off:OFF on:ON
And set the cycle step names and colors to match the pedal.
