AQ Interactive is teaming up with music keyboard specialists Korg for Korg DS-10, a music creation tool for the Nintendo DS. Wired has the story.
As you can see, this is no game: Korg is going for serious musicians who want a portable, touch-screen-controlled music creation tool they can carry around with them. As such, they're likely restricting themselves to a niche market like Jam Sessions, but it could still be a big hit with that crowd.
