i've been looking into making some sort of alternative midi controller for a while now and found the following sites this one using leds as touch sensors looks like a very interesting design idea http://mrl.nyu.edu/~jhan/ledtouch/ a few more relating to the above, http://forums.linear1.org/index.php/topic,445.0.html http://www.merl.com/publications/TR2003-035/ http://projects.dimension-x.net/technology-and-projects/ledsensors/ this project is amazing http://nnnnnnnn.org/index.php?n=0001 look at the video.....http://music.calarts.edu/~tehn/(tehn)mlr.mov just interested in what you guys think of these projects i do hope to build a midi box project but these are definitely too far out of my reach, but maybe someone here will be interested!/inspired!
