Kemper KPA External Control

The KPA has extensive, intuitive support for external controllers, and some products are made specifically for control of the KPA. The three main types of control are analog expression pedals/footswitches, MIDI, and the Kemper Remote.

Expression Pedals

The KPA has 2 stereo jacks on the back of the unit that can be connected to expression pedals or footswitches. Expression pedals should be stereo and connected with a stereo cable. Footswitches can be mono or stereo. Additionally, up to 4 expression pedals can be connected to the Kemper Remote.

System Menu Settings

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, 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 setup below. 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.

Pedal Type refers to the polarity of the expression pedal - type 1 is the normal type (Roland), while type 2 is reversed (Yamaha).

This is also where you would come to calibrate a new pedal, or after updating your KPA's firmware/OS. You simply press the button then do a full sweep. Be sure to calibrate any pedal that you add to the KPA or after you update the KPA's firmware/OS.

MIDI Assignments and Settings

While in Browser mode, page 12 allows you to assign the current rig to a MIDI Program Change number, as well as view all the MIDI assignments. Note, these are only for Browser mode, not performance mode, where more than MIDI bank of 128 rigs each can be assigned.

While in Performance mode, page 13 allows assigning external devices to the MIDI Out and Thru ports, as well as giving them device names, and specifying which channels the Kemper should use to communicate with them.

Page 14 has some 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.

Rig Menu Volume Pedal Settings

Page 5 of the Rig menu has some settings specific to using an expression pedal for volume control.

• Lock Vol. Pedal - this setting will lock the current volume pedal settings below to apply to all rigs
• Wah Pedal to Vol. - this is a rig-level override of the System Menu page 14 pedal linking option above
• Location - this refers to a volume pedal's placement in the signal chain. Since a dedicated volume pedal doesn't require an effect slot like wah wah or pitch (whammy), you use this parameter to set where it should affect the signal.
• Range - this refers to whether the volume pedal should boost when moving from heel position to toe position (when set to right of center) or cut when moving from toe to heel position (when set left of center)
