Yamaha DTXpress/DTXplorer/DTXtreme

hi i'm trying to pilot the reason's redrum by playing the dtx but i 
only have three midi lines working when i hit the other pads nothing 
happens in the redrum the sounds stay silent for all the other pads !! 
whats strange is that when i connect to the synth all the dtx pads 
play the sounds !! so why don't they play the redrum if anyone could 
help me out that would be great !!!!
thanx

I think that it is only a problem of midi notes. The pad must send the right
midi note to the redrum. You should find the midi notes used by the redrum
and then configure your kit(in the voice menu) with the right midi notes. If
you don't know which the right notes are, just hit a pad and change the midi
note each time, then write down the midi notes which work and configure your
kit.
