Yamaha DTXpress/DTXplorer/DTXtreme

Good day,

I am still trying to get a handle on triggering samples on my PC 
with the DTXpress III.

So far I have gone the long way and pulled up the midi keyboard in 
my sequencing software and hit every trigger on the drum kit and 
documented the associated midi note.  This works...but what a pain!

Then of course I found this group and saw the "DTXpress III Default 
Midi Implementation.xls" in the files section......so much for the 
long way!

Anyway - I am still unclear on the layer1 vs. layer2 distinction 
made in the xls document.

I must admit that my triggered sounds are very artificial - and I am 
wondering if the 2nd layer plays into helping resolve this.

Any information would be greatly appreciated......as is the 
information from all the contributers here!

Cheers,
