Steve,

Briefly.....you adjust the rejection settings to prevent or minimize 
cross-triggering. When you hit one pad and that pad sounds as well as 
the pad next to it also triggers, even though you only hit one pad.

There are three rejection settings:

The first is the general rejection the pad peizo has to the rest of 
the world, the rack, other thinks that make it vibrate in general.

The second is the rejection the pad has to itself. If the setting is 
too low, one strike may cause the sound to play twice, instead of 
once, because when you hit the pad hard, it doesn't instantly stop 
vibrating, so if the continuing vibration is strong enough the module 
will trigger the sound a second time, even though you only hit it 
once.

The third rejection is the pad has to a second specific adjacent pad. 
If when you hit the crash2 cymbal hard, and the vibration travels 
down the mounting arm and down to Tom4 and cause Tom4 to trigger, you 
will have to adjust the Tom4 (input 5) specific rejection setting to 
the crash2 (input 11) to a higher number until the Tom4 no longer 
triggers accidentally when you strike the crash2 pad.

When you use multiple modules the first two items can easily be 
handled, but the third is difficult, but not impossible to handle. 
You have to use up spare inputs on each module and use some Y-
splitter cables.

The way I handled it was dividing the rack up into three sections, 
left rack pads went to module 1, middle rack pads went to module 2 
and the right rack pads went to module 3. 

If your pads aren't crammed together like mine, you shouldn't have a 
problem.
