Reply to help with mapping please

ok i am looking to start a freash mapping for my hercules steel

what i want to do is when "shift" is lit up i want to be able to use the kill switches and bass,med,treb for effects 1,2,3 same on both sides of the deck

and when shift is not lit up i want them to just control eq as normal with kill switches

so i have noidea what this is called or how you do it but there are alot of people who have been here and are good at this so if anyone could help would be great
