Hi @Fen
If I understand you correctly you would like the output from Scaler to be input to Kontakt 8 to trigger the new Chord and Phrases tools, and I think I am correct in saying that these tools require a single note input rather than a chord.
Given this I suggest you could use Scaler’s multi-out to generate the notes based on patterns in Scaler, whish separates the bottom four notes of each chord across midi channels 2,3,4 and5. How you route these to Kontakt will depend on your DAW but here is a tutorial illustrating how to do this in Reaper ( Basic Introduction to Multi Out) and for other DAWs see Multi Out with Multi-timbral synths. MIDI routing basic tips and DAW Setups.
Hope this helps
