Okay, obviously electronics is not my strong suit. I hope I can explain my problem well enough that someone can help me.
I am working on an electronic drum project. I have two piezo's that need to connect to a tip/ring/sleeve jack. Both piezo's share ground on the sleeve.
I need the signal from piezo#1 to go only to the tip on the jack. The signal from piezo#2 needs to connect to both the tip and the ring to work correctly. When I connect piezo#1 to the tip, I get the expected signal for that input. When I connect piezo#2 to only the ring, I get nothing, which is also the expected signal for that input alone. When I short the tip and ring, I get the expected signal from the ring input, but I lose the "tip only" signal from piezo#1 because now both piezos obviously trigger the ring signal because of the short.
My idea was to use a diode between the tip and ring so that piezo#1 triggers only one input, but the piezo#2 triggers both. Will that work as expected? If so, how do I determine what diode type and value to use? According to my meter, the piezos put out around 350mv when activated at max.
If this won't work, can anyone tell me a better solution? I need to keep this passive if possible.
Thanks in advance, and sorry I don't know the correct terminology.
