Thanks for the reply Bohan. Yes, the three presets that have this message are in PitchFlex and QWah. That is very frustrating because I would really like the option to control different paramters in those algorithms, but I guess that is not an option. Why wouldn’t you just allow the same options within those algorithms, just like in all others?

Yes, I do use CONTROL and I can see the expression pedal ribbons and buttons, but I cannot see them move at all when I use the expression pedal. Because of that mapping message they are locked from view.
