Reply to Oxygen 25 (Oxygen 8 v3) fader problem

Hello!
For some time ago I bought a Oxygen 25, the first version with a fader. I'm currently using a slightly modified version of Ean Goldens Oxygen 8 v2-mapping and everything works perfect exept this:

I'm trying to map the fader on my Oxy to the x-fader but for some reason does the beatmasher-knob and the fader have the same "value" (CC.007).

Can i sign a new value to the fader or how should i do to make the fader work as a x-fader?

PS. Sorry for my bad english!

EDIT: Maybe I should say that I have read the official thread for Oxy-mappings without finding an answer even though someone has asked the same question as me over there... I'm hoping for some better luck by posting a new thread
