Yamaha DTXpress/DTXplorer/DTXtreme

Hi,
I'm new to this forum and was just wondering if if DTXpressII & III 
sysex files are compatible with the DTXpress 1. I downed some from the 
files section but not all of them work.  Also I'll be posting some of 
my user kits and possible short mp3 files as to how I've used the kits.

Thanks
