noisebox - a synth for the raspberry pi (and Akai LPD8)
This should work with the debian squeeze distro for raspberry pi.
the only thing you need to install is libasound2-dev, which you can do by typing
sudo apt-get install libasound2-dev
into your raspberry pi's terminal.
to make it, cd into the folder, and type "make"
Let me know if there's any problems!
