By the way, if anyone has seen conductive plastic or metal fader caps for sale somewhere, I'd appreciate a steer. I have found straight plastic ones at Mouser, but I'm looking for a supplier of ones that will allow me to sense a finger on the fader. I know I can order them as spare parts from audio console manufacturers, but I'd prefer to find a farther upstream source. As for the status of my project, I've thrown together a quick demo board (well, an add on to an existing board), but I won't get to try it out for at least a month. Ah well! Thanks for the help!
