Reply to How Do I Re-Map Some Instant Gratification Effects

I am new to mapping, so forgive me if this is a very easy/dumb question (I searched around the community s and couldn't find an answer though).

I have the instant gratification mapping up and running with no problems with my S4, but I want to remap the beatmasher effects to only a 50% wet/dry instead of the default (which is 100% wet). How would I go about making that change?
