 I too, have the same issue! when playing as Ed said "heat of the 
battle" and do an accent of snare and cymbbal, the kick almost always 
will not sound, And I am certainly kicking it! I have tried it with 
the tower yammy set up , as well as a pintech trigger,the small 
cylindrical one (scientific,no?) and the results are about the same. 
I did have some issues with the yammy stand up trigger,and had to 
disassemble and solder the jack terminals back solidly to the pc 
board...that cured the hit/no sound, but not the no kick response 
when hitting cymbal(any) and or cymbal/snare /kick...any ideas Ed? kb
