Yamaha DTXpress/DTXplorer/DTXtreme

Here's what I'd like to do:  Assign pads 1-8 to differant MIDI 
channels and then play the song and record the drum kit with each DTX 
pad sending MIDI data to an assigned MIDI channel in Cakewalk Pro 
Audio 6.0.  Then have Cakewalk play back the multi-channel MIDI 
sequence through the DTX brain and still be able to set individual pad 
values for voice, pitch, velocity, pan, etc. 

First of all: This is actually possible...Right?

Secondly:  I've been reading both the CW and DTX manuals and it looks 
like this is going to involve sending SysEx messages from CW to the 
DTX to select a drum kit # and then use the buttons on the DTX the 
usual way to set the desired pad values.  Is that the general idea?  I 
realize this probably invovles too many steps to deal with in one Q/A 
but I'd appreciate any help to at least get started out right and then 
I'll follow up from there.

thanks,
Hooper
