Yamaha DTXpress/DTXplorer/DTXtreme

Hello everyone!

I'm trying to get recommendations on how to configure my current 
setup such that I can record each drum to a separate track on my 
Cubasis VST recording setup.

Here's how things are configured, more or less...  The primary 
objective of how it's setup is to allow all instruments to play 
simultaneously during practice sessions, and to allow one instrument 
at a time to record to the PC.

I've got the following equipment:
AX-212 Amp
Tascam 4 port cassette recorder acting as a mixer

Fender electric guitar (to the guitar in on the Ax-212)

Yamaha Electric Piano (to the Tascam Line-In) 
Yamaha DTExpress 2.0 audio out (to the Tascam Line-in) (midi out/in 
to the USB-122 on the recording PC)
Line6 POD (mono out to the Tascam line-in)
Mic (to the last Tascam line-in)

And Finally, the Tascam line-out goes to the AX-212 Aux-in for 
amplification, allowing me to play to the everything to the room 
through the AX-212 (for live practice).

For recording, I take the line out from the AX-212 to the USB-122 to 
record on the PC. With this line, I can record the audio out from 
any instrument in my setup.

And audio recording works wonderfully.

What I'm trying to setup now is midi from the DTxpress.

For recording, I've got local=off, on my dtxpress, and my USB-122 
Midi port is echoing my notes back perfectly during my original 
recording session. (sync seems ok.  latency, too)

However, all the midi records to one track (I've got that track set 
to record from "any" midi channel), and I want them to show 
up as the drum pad I hit, vs. a note, that isn't actually labeled as 
what I hit.  I'd also like to be able to record each drum to a 
different track in Cubasis VST.

Is this possible?  I haven't found any documentation that shows how 
to set this up, so I wonder if I'm just dreaming.

I'm guessing that the way to configure this is to put each pad that 
I'm using on a separate midi channel, then enable each track in my 
s/w to record that channel.  Am I offbase?  

How do I save that config on my DTXpress?  Will that require a full 
dump of the sysex, or can I just save that as a drumkit?

If the best you can do is to recommend a good book on the general 
topic, I'd be glad to get that feedback as well!
Maybe this is more of a question for a cubasis or USB122 group, but 
I've read info on this group some time, and this group gives better 
feedback than most!

Thanks!
