Hey Guys,
I have not a clue how to stop this. Ive set all my triggers to where 
its not too bad yet still not enough. Every time i get done on my 
real snare, certian pads want to trigger. i cant have that..LOL

To explain, what Ive have done is custom re-arranged the rack so 
that i have 5 pads scatter stack in 2 rows. Its located just to the 
right of my hit-hat and snare. (I'll do a pic if needed)One pad is 
about 8 inches from the snare and keeps triggering. What do ya'll 
suggest here. My options are limited on moving the rack, its the 
best place to have it and very easy to get to.
Thanks,
Wm
