Yamaha DTXpress/DTXplorer/DTXtreme

Hello,
I am new to the dtxpress. My drummer has one, but he lost his manual 
and I am trying to figure out how we can program some pad songs into 
it. I finally found this place and the dtxpressions site, does anyone 
know of any other good user sites, or anywhere that I can download a 
copy of the dtxpress manual? I can't find it anywhere on yamaha's 
site. Anyways here is my setup, if anyone can point me in the right 
direction that would be great. 

I have an akai mpc2000, and the yamaha dtxpress. I have been trying
to 
midi them up, so I can hit the drum pads on the mpc and trigger the 
dtxpress's internal drum sounds. I found some info on the 
dtxpression's site about the host select switch, that may be what I 
was missing I will try that tonight. I have the midi out from the mpc 
going to midi in on the dtxpress. I set them both to the same midi 
channel, and I even found the setting in the dtxpress that lets you 
set the sounds to either midigm or drumsv or whatever and set those
to 
drums. When I hit the drum pads on the mpc, sending midi note data to 
the dtxpress I get nothing (no sound is trigger). Is there anything 
else that I could be missing. I just found out about host select so I 
am thinking that might not be set to midi. 

My second question, since I don't have the manual, how do you go
about 
recording a pad song? If anyone could point me in the right direction 
I would really appreciate it. Even just a list of click this, change 
that would work, I am good at figuring this stuff out,  I just don't 
know where to start without the manual. Thanks for your time. Peace
