Yamaha DTXpress/DTXplorer/DTXtreme

hi , from my limited knoledge it's imposible to transfer new sounds
to the dtxpress , and explorer modules , one can only use internal
sounds with different settings . the dtextd only does that , 
PS the dtxplorer sounds way better than the dtxpress I and II and
maybe III ,but has limited pad inputs and settings  i play a dtxplorer
and for playng live the high hat and cymbals sound beeter than the
previous versions because it has some of the dtxpress IV sounds 
I can help you with some explorer settings if you want
