Yamaha DTXpress/DTXplorer/DTXtreme

As far as I know, the stereo Yam. pads only have a polarity switch 
and sensitivity knob on the back, right? Everything else is set 
elsewhere. Forget the polarity switch; it has no effect on what you 
hear through the brain. The sensitivity knob is an extra gain 
setting. Leave it in the middle, unless someday for some strange 
reason, you just can't live without turning it up or down a little. 
If it's too high, I guarantee you'll start hearing pops that you 
know didn't come from you. Min.vel. determines how softly you can 
hit and still hear something. Use it in conjunction with gain, which 
determines the force with which your hits register, to set your 
dynamic range. But remember, if you set min. vel. too low or gain 
too high, you'll be asking for crosstalk from other pads, because 
your pads are so sensitive or so hot that they start picking up 
every vibration in the neighborhood. As my father and Aristotle used 
to say, moderation is the key. Get a balance between gain and min. 
vel. that you can live with. Then set the volume controls--for 
individual pads under the voice menu, for the entire kit in utility, 
and for kick/snare and toms/cymbals on the front of the module--to 
your liking. Be prepared to fiddle a lot. 

The DTX has a certain amount of redundancy, but attending to only 
one of these parameters will not substitute for what the others do. 
Unfortunately, there's no single intuitive way to put e-drums in 
order. It takes a lot of trial and error--sometimes detracting from 
ability just to play. But eventually you find basic settings that 
you won't have to vary too much. And, yes, they'll have a lot to do 
with your playing style. You can't please all of the people all of 
the time with the same numbers.
