This may very well be the GENIUS solution!!! I will test this evening/overnight. I think that would involve an additional MIDI In block for the keyboard slope range’s NoteFolowValue parameter. I will see how far I can get with this. Thank you!
I don’t know about genius but it help to know what one is actually trying to accomplish. Cross fading is really trivial in GP
I’m still at my day job so this is untested, but it comes to mind that that will only work for a mono keyboard run across the range. If I play a chord across the cross fade range, the last key played always defines the mix volume.
I think this puts me back to cross fading the MIDI velocity based on the FollowKey=On and FollowKeyValue and the script samples I will try. Tonight I will have some stare time to make some progress. 
Yes but unless your notes are extremely far apart you probably won’t notice.
You could of course use GPScript to start averaging the values of the notes in a chord😉
This is the exact thing I was looking to do!!! Thank you! This works very smoothly across the key ranges.
This provides the behavior that I can get from the Kronos/Nautilus “velocity zones” tab in Combi mode. 
That is the perfect companion to a MIDI In block when building layers and splits needing slopes.

Great! Glad it worked for you.
Maybe it even would be better in addition with David’s approach… at least something you could try.
EDIT/HINT: Rightclick the Scriptlet block and save it as “Favorite”, so you always have it “at hand” and you can easily insert it in a rackspace if you need it (Just select it from Favorites-List).
