Barry,
In Kontakt Options/Engine/Send Midi to the Outside World, make sure you have Script Generated CCs and Script Generated Notes selected.
It can be a pain setting up Midi VST outputs etc… Here’s a link to the manual from an older product of mine which has sections for setting up Midi VST outputs in various DAWs, Live and Studio One are included.

I would first get it working in Kontakt Standalone to make sure it works, that will at least only leave the Midi Routing inside to Deal with.
There’s no sysex, Kontakt doesn’t support it so it is all just NRPNs.
