First time I listened to Ketron, and I'm pretty impressed. I believe it will be released January 2009?

I read on the site that some of the tracks in Ketron styles are audio and some are MIDI. Can someone explain how this works? Are the samples on the website audio drums or MIDI?

Reason I want to know is bc I make my own styles and would like to know if they will sound like this if I use just MIDI.
