Yamaha DTXpress/DTXplorer/DTXtreme

HI ALL!  Its been a while since I've posted, I have been reading the 
boards tho faithfully everyday. Anyhoo, here's my questions:

1. I've seen a whole bunch of really awesome kits in the pics section,
    and i was wondering if i could hear some of these kits in 
action ,maybe some members could record a small solo, and add the mp3 
to the files section ...under "kits in action". or if youve recorded 
a song or something with the drums on it would be swell!

2. Adding midi files from my comp to the dtxpressII module, in user 
songs..... I have about 1000 or so midi files from the net of almost 
every genre, and would love to add these files ... or 32 anyway to my 
user songs section... would i be able to do this ,  if i edit the 
songs in cakewalk, and take out the drum parts , then save the file, 
could i upload it at all, and how? and would I need the comp to play 
them all the time, or can I disconnect to play live with the band.

Thanks for your time. 

Jaymz.
