EXS 24 Logic Sampler Users Group

I have been trying to use the next instrument function . The one in the 
preferences where you can set up instrument changes with a midi note, a 
controler...I can make changes with the wheel but I don't seem to be 
having any luck with notes I enter the midi number and nothing. It 
worked in L6 but in L7 I can't seem to get it to work. Not sure if it's 
pilot error or an insect.
