You can add the KAT KT1 e-kit to the "mostly works" category. Unless someone knows how to fix the problem I'm having with my cymbals. I did have to switch my ride and crash cymbals around, but I'm sure that's common. My problem is that my crash/ride cymbals have trouble registering if they are hit the same time as the hi-hat. I have the MPA, and i've messed with the sensitivity countless times..no luck.
