DSMI - MIDI for the Nintendo DS

"So what is DSMI exactly?
DSMI consists of
* libdsmi
An open source library for DS homebrew development that makes it easy to write DS software that acts as a MIDI controller or MIDI client.

* DSMIDIWiFi Server
An application that runs on the computer and forwards the MIDI messages received via Wifi to MIDI applications.

* DS MIDI Keyboard acts as a MIDI keyboard, including pitch wheel / MIDI control adjustment by sliding the stylus vertically/horizonally.
o Kaos DS is an XY controller similar to the Kaoss pad. You can use the stylus or your fingers to adjust MIDI controls.
o Pulse DS turns the DS into a MIDI synthesizer that uses the DS's PSG (programmable sound generator) to produce Game-Boy-like sounds.

What do I need? In short, you need:
* A computer of some sort (OSX, Linux, Windows will do just fine)
* Either A wireless access point of some sort and a game that uses the Nintendo Wi-Fi Connection (needed only once)
* Or A DSerial
* A Nintendo DS, obviously
* DS homebrew hardware of some sort"

Update via BirdFLU in the comments: "Just to clarify, the DSMI stuff won't work in tandem with the DS-10."
