From the Alesis site's decription.

"The world's first-ever drum module to let you keep it fresh
So, not only do you have an astounding collection of sounds in the DM10 Pro Kit's DM10 module, you've got the world's first-ever drum module to let you load in new sounds via USB. That way, you can always keep your sound fresh, current, and on the cutting edge. Naturally, you can also use the DM10 Pro Kit has a trigger-to-MIDI interface, for performing or working with your favorite software... be it BFD, Toontrack, Reason, or whatever else you dig. And when it's time to practice that solo you've been meaning to, you've got an input for your iPod or MP3 player... just put on your headphones, press play, and get going."

So, did I mis-read this?
