Yamaha DTXpress/DTXplorer/DTXtreme

Im afraid Im not a drummer, Ive bought a DTXpressII to use in my home 
studio. 

It seems great - so I now want to get rid of my old Yamaha rythm 
generator(DD11) - BUT - I cant seem to find a way to get the DTXpress 
to replace the simple things that the DD11 did.

Question: - Is there a way I can use the DTXpress as a simple rythm 
pattern generator to play along with when there's no durummer around?



Ive tried hooking the DTXpress up to my PC and Cakewalk Music Creator 
software and sending a one-bar pattern to record in one of the user 
song areas on repeat - but I cant seem to get the sync start message 
going, and my finger isnt fast enough to push the DTXpress record 
button without creating a timing gap.

All help gratefully received.
