XSonic Airstep and Kemper Profiler Player III - documenting my settings

Here are my notes about how I have set up the XSonic Airstep and Airstep Lite to work with my Kemper Profiler Player III. The USB MIDI adapter is MVAVE.

Note: The Airstep has a Preset for KPA, but I found that these settings work better (triggering Morph just like on the Kemper Remote/Stage, for example).

Rig Buttons

This is a summary of the settings on the Airstep to make it mimic the behaviour of the Kemper rig buttons one through five.

Detailed Configuration
Here are the detailed settings laid out to match the way you will enter them in the Airstep app.

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 This 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 behaviour 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)

When I use both the Airstep and the Airstep Lite, I use the Airstep for Rig buttons (above) and the Airstep Lite for Effects Buttons (below)

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 I change 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.

Looper - see next post

Here's the documentation for the Looper functions on the Airstep or Airstep Lite.

For each function (e.g. Rec/Play/Overdub), there is a table with five rows. Each row represents an Airstep "Message". All the values are the same except for the second row in each table (88,89,90,91,92,93)
