Hi. I'm about 70% of the way towards a working kit. But I'm not able to map the rim and bells to my three-zone Yamaha cymbal pads. I read in one post that it's not possible to use the choke with the DTXtreme IIs module, but I hope that I can still get a rim and bell sound. Do I have to buy a special expansion pack to get those sounds to work. Or do I need to move up the the big BFD2 pack, instead of ECO? thanks for your help -ab
