Pages 5 - 10 cover how expression pedals behave. Pedals 1 and 2 cover the two inputs on the back of the KPA, while Pedals 3 - 6 refer to inputs on the official Kemper remote. The setup done here is simply mapping the pedal's anolog input to that appropriate MIDI CC # (1 for wah wah, 7 for volume, 4 for pitch, and 73 for monitor volume).
Note: if you only have one expression pedal, you can still use it to control wah, volume, and pitch with some additional [[#MIDI Assignments and Settings|MIDI setup below]]. You should set it to CC# 1 (Wah Wah). The KPA is actually very smart about this, and you don't really ever need more than one expression pedal, unless you like to have dedicated pedals, or have your wah/pitch with a spring in it to push it back to heel position, or do some crazy stuff where you jump between pedals.
==== MIDI Assignments and Settings ====
Page 14 has some checkbox settings for allowing an expression pedal that was set to Wah Wah on pages 5 - 10 or MIDI CC 1 to also control volume or pitch-shifting, when not being used for a wah wah effect. It also has settings for sending the KPA's MIDI clock to external devices and setting the MIDI global channel (omni by default). And you can also see the current MIDI CC values for 4 of the most likely used CC's, controlling modulation, pitch, volume, and monitor volume.
'''Note, if you link a wah pedal to volume, when you disable a wah effect on a rig, the pedal will ''not'' begin to control volume until you put it fully in the toe position''' - ''this prevents a jump in volume if your wah pedal is not in toe position when you turn it off''. Similarly, if wah is linked to pitch, when you disable wah/enable pitch, the pedal will ''not'' begin to affect the pitch until it is brought fully to the ''heel'' position, again to prevent the pitch jumping on the transition.
