Yamaha DTXpress/DTXplorer/DTXtreme

I am trying to send MIDI signals to Cubase. All of of my triggers send
a signal except for the snare and kick. I believe that they are mapped
incorrectly. Is this normal? Should I try to solve the issue in Cubase
or in the DTX brain? I looked at the Drum Map in Cubase and it looks
like I could easily spend the rest of my life trying to figure out
with trial and error which trigger sends what. Is there an easier way
to do this?


And on a side note, I created a few .syx files of some of my most used
kits if anyone is interested. Let me know and I will post them in the
Files. I have a decent Zep kit, some hard and heavy kits, and a few
nice all around rock kits.
