Not quite on topic, but since this list has the highest concentration of smart gear geeks I know, I figured I'd ask before trying (and maybe frying). I have a Roland EV-5 continuous controller pedal that I'd like to use to control 2 devices, a Moogerfooger filter pedal and a Line 6 DL4. It works with either individually. Can I share it between both with a headphone splitter Y cable? The only problem I can think of is that one of the wires is carrying a voltage from the device to the pedal, if the output voltage is the same from both devices, I can clip one wire so only one device is sending to the pedal. I almost never use both devices together, and really only want to control one patch on the DL4. Am I being completely stupid here?
