S2 controlling FX unit 1&2 X1 controlling FX 3&4?

I’m quite new to Traktor, I recently bought an S2 and soon after that I bought an X1. I was hoping you could help me map the x1 to control FX units 3&4 since my attempts at doing so have been terrible. Thanks!

Have you checked the mappings section of the site for something first?
