Reply to Midi Fighter pro custom mapping help!

Hey guys!
I'm on the verge of buying a midi fighter pro to use with my S2, but i just need a little reassurance, and help before i commit. I am gonna write my own mapping for it, but i wanna know first how simple the mapping of the LED's are, just so they light up when i hit the cue buttons, and show when toggle controls like the looper and echo freeze are on. If that is going to be simple, then i'll be ordering my MFP asap!

Thanks!
