Yamaha DTXpress/DTXplorer/DTXtreme

Hi,

I'm searching Midi Drum tracks/loops ? There are a lot of CDs with 
Drum Loops on the market but is there something like that with Midi 
files only (played from a real drummer, not from a drum machine... 
you know, with fills, ghost notes, rolls,...). 

I have DTXpress but I'm a guitarist and my drum tech. is not really 
that good for the moment... so if I could find/buy midi loops/tracks, 
that would help me a lot ! :)

Any ideas ?

Thanks  :)
