Yamaha DTXpress/DTXplorer/DTXtreme

hi, new to the group just bought my dtxpress on wednesday.

My problem is i can get midi to Logic Audio Platinum, and I can get 
midi back to my DTXPress, but some reason the only sound I can get 
from dtx when i play back is the basic midi sounds, and not the drum 
sounds, and when i send the data out through channel 10, it's 
completely mute. nothing.

can anybody help me with this? it's really annoying and i'd like to 
be able to use the sounds from my dtx. thanks in advance.
