So I was setting up my Kemper set up for tonight's gig. I work in performance mode and was setting up wahs and pitch control functions for certain songs. I figured that since I was using performance mode, I when I stores each rig, it would also store weather the expression pedal was in wah function or pitch function. But it appears that is a global system function and I have to choose between wah, pitch, etc Does that mean I have to get another another expression pedal or is there a work around to use it for both
