I am new to BFD3 and samples so bear with me on my description. Bfd3 installed on laptop, kit created with no problem. I have a Dtxtreme 3 edrum set with the dtx900 upgrade in the brain. All multiple zone pads trigger properly when tested however when 2 different pads are hit together only 1 triggers the sound the other drops out. Bass and snare together only get bass sound for example.
