Wiring for multiple piezo triggers

I'm building a little box to connect 2 piezo drum triggers (kick & snare), and convert them to USB-midi signals. I followed Paul's advice given in this forum thread for connecting one piezo trigger, and it's working great.

To connect a second piezo trigger (or maybe more, in the future) am I correct in thinking that I would need an additional 2 diodes and 2 resistors per transducer, basically replicating the given circuit for every additional input? Or is there a better way?

Thanks!
