Have a PC, a webcam and a printer? You’ve got all the tools you need for this free, do-it-yourself synthesizer. The D-Touch DIY Tactile Synthesizer and Drum Machine is a software-based, hardware-controlled system where the hardware is absolutely free. Just print out the paper control surface, form the cubic control pieces and set up your webcam accordingly. When you move the pieces horizontally or vertically, it changes the timing and other control parameters of your drums and samples. Awesome! [plans available free at d-touch.org]
