Scarbee Bass hammer on/off

I like the Scarbee Bass products. They don't sound much like my own playing since i use flat wound strings, but its a good sound and i want to use Pre-Bass in a live setting. The problem is i want tighter control over the hammer on/off. Its triggered by how legato you play and its incredibly sensitive. To avoid it i have to play super choppy which is silly and makes the bass lines sound different. It should be controlled by a keyswitch like everything else.

Anyway here's my question, I notice that all the Articulations are controlled by Nil's amazing Kontakt scripting. Is there a way to edit this script, or at least change the sensitivity/threshold of the legato Hammer on/off trigger?

Thanks!
