Trying to explain it as simple as possible:
Using the Kemper Stage with one Expression Pedal (Zoom FP02M).
Connected to input 3 - out of the box setting "Wah".
Setting Wah to Vol and Wah to Pitch is activated.
When I have the Volume on 100% and activate the pitch or Wah stomp they are on 100% each - means, the pitch is up 1 or 2 octaves, depending on the effect in toe position, when switching on e.g. stomp A.
When I switch the stomp off the Vol stays at 100%, even if the Pedal is set to 50%.
I watched the Kemper Expression Pedal Tutorial (German and English) several times now, and they only make the example with Morph to Wah and Pitch and they state that "the pedal has to be brought to heel position after switching on the stomp, before the effect is active". Which is not the case for me currently. But I have to move the expression pedal after switching of the stomp to make it a volume pedal again...?
My goal is:
Having Volume on 100%, switching on a Wah or Pitch stomp, but nothing changes.
Moving the expression pedal to heel and from there the Pitch and/or Wah starts working.
Moving the expression pedal back to heel (or where ever) and switching of the stomp - effect is off, but volume is not affected.
Moving the expression pedal IF I want to change the volume now.
