Hello! I am trying to get an expression pedal to work on my m5 by going through a midi controller. Not sure where i'm going wrong. I am using an ex-1 > decibel 11/switch dr. (cc#1) > m5 via midi. I can change presets with no problem but can't get the expression pedal to work. Any ideas out there. Your ideas and time are greatly appreciated!!
