MIDIsense

MIDIsense is a simple, yet extensible sensor interface system for artists, musicians and others interested in experimenting with sensors. The MIDIsense boards provide a simple way to integrate various common sensors with existing software such as Max/MSP, Ableton Live, etc. or directly to a synthesizer/sequencer with a MIDI in jack. Interface boards are available as kits and (possibly) assembled. Graphical configuration/calibration software is written in wx/Python and wx/C++ and is available for MacOS X or Windows as executable. Linux is not explicitly supported right now.

While there are other projects with similar functionality, this one is the most technically advanced, flexible & inexpensive.
