Yamaha DTXpress/DTXplorer/DTXtreme

I am a new user on this site.  Have just purchased a dtxpress module 
for my electronic drumkit which is great. I have downloaded some kits 
from this site which were posted by Chris Thackston in 1999 but would 
like more sysex kits that will work with my original dtxpress.

Have attempted to download other kits from this site but they don't 
work and assume that they are only compatible with later versions of 
dtxpress ii, iii and iV 

Does anyone have any kits that will work with original dtxpress 
module and can anyone tell me if there is an editor like deEXTD which 
will work with my dtxpress.

Finally I am interested in establishing how I can create sounds in a 
music package and then create a kit for the dtxplorer and would 
appreciate any advice or recommendations as to what software I need.


Thanks
