Are you familiar with mapping led's in Cross?
If not, it's gonna take some time/patience to get familiar with it. Here are a couple of threads that helped me when i got CrossDJ.

The alias to use is "Out fam(Mixer).ChannelAMeter (Normal)" Obviously changing ChannelA to ChannelB & C etc....
Forum member DzsoniB was extremely helpful, as is his mapping utlity. Give it a try, It's actually not too bad once you understand it a bit.
