I want to use the Rotor cabinet effect in the ms70, but I would like to use the switch to change from fast to slow parameter. But I don´t know how to do it... If not i would have to be changing this by hand turning the central button.... :-( Thanks
This sounds like an interesting problem to solve. Try checking the pedal switch settings and make sure the wires are connected well. I hope you find the right fix and get it working soon!
