Yamaha DTXpress/DTXplorer/DTXtreme

I was under the impression that I could use the Y-splitter on the 
9/10 to lead to 2 separate mono drums with each of the two 
triggering 9 and 10. I tried that, but both pads only pick up pad 
#9. Both of the pads are Yamaha rubber pads.

Another question, I noticed that the copy command works like a 
charm, but as soon as I modify the original trigger that was being 
copied, the new trigger changes as well. Is there any way to make a 
copy of all the settings on a trigger (Gain, volume, etc...) to 
another trigger and not have the new trigger "link" to the original?
