Yamaha DTXpress/DTXplorer/DTXtreme

Just joined this group today having found you all by accident. I 
recently purchased the Roland KD-80 kick trigger (v-drum)and was 
dissappointed with the compatability when i plugged it into the       
DTEXPRESS111 module. After being told by sweetwater sound it would 
work."it's just a trigger there's no mystery to it" Here's the
problem.
I play double bass and alot of syncapated rythms with my single pedal 
as well the KD-80 will not register every beat it skips every other 
beat. I tried changing the input gain,minimum velocity and velocity 
curve as outlined on pages 38-39 in the manual with no resolution.Any 
body have any suggestions before i box this up and send it back. and 
loose 10 to 20% plus postage. 

respectfully submitted,
