The developers that made this drum machine did one hell of a nice job. This is super cool. They have a demo MP3 that was created with the drum machine. This is a home brew application and therefore will work only on firmware less then 2.0. Hopefully SONY will get their head out of their ass soon and realize that there are developers like these folks that can make some cool stuff happen if given the chance. This is the kind of stuff that will sell the units - not their high priced games and movies. They are really dumb for not letting the home brew community grow and keep the platform open.
