Adjust Velocity Setting

Within Halion Sonic 3 there is a Rhodes patch called “Warn-Out Suitcase”. It’s very nice but has some velocity settings I would like to edit/disable (i.e. if you press the keys harder, a different sound is played). This patch appears to be part of the Halion Sonic SE2 Pro Set. Does anyone know of a way to edit this patch and change the velocity settings?

Thank you!!!
