So you have your chords in the Master Track.
Drag the midi into a new track, while it still in absolute form move it from left to right across the chord changes you will see the notes stay in the same position - now convert to relative and move left to right and you will see the notes adjust to fit chord/scale notes.
If you double click it will open up in the editor - in the View Option check color note by chord/scale/out-of-scale - this will give green chord note - blue scale note - red out.

You can use absolute midi to put under the existing midi pattern for keyswitch articulations in Kontakt - so you can have an associated keyswitch midi for a pattern so no matter where you have it in the chord track it will do the same keyswitches.
