Reply to Dicer Mapping Help!

Hey everybody!

So I never use any of the traktor mappings for the orange section of my novation dicers, I was wondering if anyone knew how to map both:

a) an echo freeze onto one of the buttons and
b) a gater effect onto one or two of the buttons.

I am a noobie when it comes to mappings, can someone point me in the right direction!? Thanks in advance for your help!
