Yamaha DTXpress/DTXplorer/DTXtreme

I have been various messages in the DTXpress group for the past few 
days and have a good understanding of what the DTXpress can do and 
not do. I can see the obvious "limitations" of the setup (ie Rubber 
pads) and it's obvious the "bang for the buck" that all the current 
owners tout.

I was hoping that maybe current owners or former owners could list 
the most glaring gripes about the limitations of the unit. 
Specifically I am looking to see what this unit can't do in 
comparison to more expensive drum modules. 


I am curious to see if there are any limitations to the midi 
information the dtxpress sends to other devices. 

Perhaps you can point me to a FAQ on the DTXpress or something that 
handles these requests. Thanks for reading.. I appreciate any help 
provided.
