This may be of interest to the group. I made a DIY touch controller last year, inspired by the Buchla controllers we have at Mills College. Mine uses FSR senors rather than touch capacitance. Each sensor has cv out with adjustable range and a trigger out. There is also a master trigger out and a Softpot "ribbon" sensor from Spectrasymbol. A very simple circuit - just voltage dividers and a comparator for triggers. It has been incredibly useful and has really opened up the performance versatility of a small modular system.
