So after watching the following video.

I was wondering, since my MidiFighter has all the beat masher effect presets already mapped, could I some how "unmap" the two sets of effect units of FX units on my S4 and map them in the way shown in the video?

This probabably isn't in the correct forum cat. But even as a general question, I'm interested how to you guys have easily unmapped certain functions on the S4.
