Remo Silent Stroke & rt-30K trigger

My Rt-30k (plugged into td-27) is triggering very well. I have to play quite hard hits on the kick (remo silent stroke) to get a trigger. I've tried adjusting the sensitivity but that only makes the velocity of the hit louder and not actually more sensitive to the physical hit. Anyone have recommendations? I currently have the head tuned very slack as tight made things worse.
