These are the settings on the Airstep to make it mimic the behaviour of the Kemper rig buttons one through five

Summary of Kemper MIDI Logic (Slots + Morph)
- CC#50–54: Load Slots 1–5 in Performance Mode or Rigs 1–5 in Browser Mode.
- Morph Triggering: If the same CC is sent again (with value 1–127), Morph is engaged.
- Morph Release: Sending value 0 disengages Morph.
- Momentary vs Latching: Controlled by the Rig’s internal “Momentary” setting.
Why Your Airstep Setup Works
- Press = CC#50–54 value 1 → Loads Rig or Slot
- Release = CC#50–54 value 0 → Ends Morph (if Momentary is enabled)
- Repeated Presses → Toggle Morph (if Momentary is disabled)
- Single Button Logic → Matches Kemper Stage/Remote behavior exactly
Kemper MIDI Documentation
- If Rig Button Morph is activated in System Settings, and the PROFILER receives subsequent control changes #50-#54 following the initial Slot load, these will trigger Morphing.
So, the same button could be used to first load a Rig, and then act as a Morph Button for that Rig. To support all functions, values 1-127 should be sent when the button is hit, and value 0 should follow when the button is released. The setting of the “Momentary” option in Rig Settings determines whether the Morphing latches the morph sound and base sound, or if it immediately returns to the base sound as soon as you release the button.
Effects Stomps
Airstep Bank 2 – Stomp Mode Control (Kemper Profile Player)
I CC# 75-78 to map to Effects buttons 1-4, and the last button set to Tuner on/off. I did this instead of using CC# 17-22, which map to Modules A-D because sometimes I use the Kemper Profile Player without the Airstep, and I wanted to use the Kemper Player mapping instead of the Profiler mappings. If changes the Effects buttons 1-4 on the Player, I wanted the Airstep to match.

Notes
- Toggle Mode On lets the Airstep track internal switch state, so LEDs reflect effect status (assuming Kemper doesn’t override).
- CC#75–79 are fully valid and can be assigned to any effect slot in Kemper’s MIDI settings.
- You can remap these CCs in Kemper’s System Settings to match your preferred stomp layout.
