UPDATE: Here is the download. This is what German hacker/student/musician Tob, who created the cool NitroTracker old-school tracker app for the DS has been working on: Software to turn put easy-to-use MIDI into the Nintendo DS using WiFi. Previously, you've had to use hardware. The DS obviously sucks as a keyboard, but is great as a little X-Y controller like a Kaoss Pad, and presumably there's no reason why he can't build a simple XOX drum programmer, a little Lemur clone, or even a virtual Monome. Tob is still developing the software - as you can see from the video, it's in a pretty early stage - but it will be released ASAP. And even if you don't have a DS, stick with this video long enough to hear the guy playing 'We Will Rock You' though the onboard sounds...

Same approach, but between a Palm and a Mac (oh and it uses BT instead of Wi-fi): http://www.bhajis-garden.org/story.php?id=31
No on-screen keyboard, but a bunch of trigger buttons, assignable knobs and a X-Y controller.
It's neat how people are starting to use the DS as a viable music making instrument, from homebrew type stuff to official software like Daigasso! Band Brothers, Gunpey (a puzzle game that has a sequencer as an extra), and M-06, the acoustic guitar software.
Here's someone using Gunpey with a KAOSS pad (found via GameSetWatch:
I used the DS for some work on my latest two albums -- it's experimental electronic, broken-beat, ambient, pop style music so please spread it around on iTunes! Used mostly in this album and this album! -- Please support independent music!
