Reply to Kontrol S4 touch strip

Looking at the new x1 mk2 ... The power of touchstrips just makes me so jealous. However, i want the capability of that directly in my s4, not in another controller.

Anyone out there have any idea how i would be able to do this and mod my s4? been looking at these, but have no idea how i would go about mapping it to do the same job as the touch strip in the x1... or if this is even possible?

Any input would be really appreciated
