MIDI-Jammer turns your DS into a wireless MIDI Controller. It lets you “draw” musical ideas and shapes in a manner that is both easy to pickup for a non-musician and also consistent/coherent enough that those who are trained musicians can have a high-degree of MIDI control through the interface.

Changes:

I just upgraded it and added a preset feature, and I’m officially labeling this the 3.0 release. The basic thing is that you can now set presets to directions / buttons and choose them by holding them down (similarly to Jam Sessions). I have created a documentation README.txt that’s bundled in with the new release at my site.
