Thanks I will try that also . If I use several effects I believe I can assign all the mix controls to the same expression pedal using external controllers ,correct ?I remember reading on the forums somewhere that the same external controller can be assigned to several parameters ie: ea mix control,then assign that ext cntrl to an expression pedal or do I need to assaign seperate external controllers(1,2,3 etc) to ea mix and then assign all the external controllers to the same expression pedal
