**Question about S4 Effect knobs in 4 FX mode**

Is it possible to make the effects banks on S4 always control FX 1/2 even when in 4 FX mode ?

The default S4 mapping will switch the effects knobs to control 3/4 when in deck c/d.

Reason im asking is because I have an extra X1 that I want to use for FX 3/4 and some other things to supplement S4. But the S4 mapping is locked down, and im not sure how to make a user mapping to accomplish what I need.

Anyone done this before, or is it impossible ?

Go to [thetraktorbible.com](http://thetraktorbible.com). There is a 4 fx user mapping that goes on top of the active mapping to do this. I would link it, but I’m on my phone
