Yamaha DTXpress/DTXplorer/DTXtreme

Happy Thanks Giving to all:)

This DTXchange I've read, and if I understand correctly (probably 
not though) is able to download more kits to your computer, then 
load it into your drum module?

But what does this really mean? Do I get more sounds of different 
drum samples? Or does this mean that other users have selected the 
existing DTXpress samples and have arrange them into 'their' 
prefered kit with their own choice of snare, kick, hats, etc...? If 
the later, I'm not sure I see the point as I can scroll through the 
samples fpr each pad myself to choose my own desired kit. In fact I 
do this often!
Now if this all means 'new' sampled sounds, then hell yes, I want!

Con' sumbud splain' ere?
