MK3 How to split analog and Komplete Kontrol

I found this post: https://support.native-instruments.com/hc/de/articles/6677865492253-How-to-use-Advanced-MIDI-Routing-with-the-Kontrol-S-Series-MK3

Example 2: Split Keyboard to Play Hardware and NKS Instruments (Advanced)

Configuration:

Global hardware settings: MIDI out Dual

Template settings: MIDI Output port = Global

Keyzones:

Keyzone 1 (external MIDI instrument): Color=Red, Channel=2, Priority=Keyzone

Keyzone 2 (NKS): Color = Blue, Channel=1, Priority=Plugin

Hardware / External instrument setup: Only listens to channel 2
NKS Instruments (Komplete Kontrol or Kontakt 8) setup: Only listen to channel 1

Usage:

This setup uses MIDI channels to separate the two instruments.

MIDI Out Dual ensures MIDI is sent to both USB and 5-pin DIN in NKS mode.

Priority = Keyzone ensures the keyzone channel assignments remain active in NKS mode.

Result:

Play your external MIDI instrument with the left (red) side of the keyboard.

Play your NKS instrument with the right (blue) side.

Switch freely between the MIDI page (to tweak your hardware) and Plugin page (to control the NKS instrument) — the split routing stays active.

So I did this exactly:

The sound of Komplete Kontrol is spilled all over the keyboard (all 88 keys)
And the external Synths are where they should be.

I also tried to change the input settings (all four of them):

I only hear sound from Komplete Kontrol when KONTROL S88 MK3 (Main) is CHECKED


I guess I have one setting missing… But I don't know which one…


I am thankful for any help
