I have seen lots of posts on the wiring for splitting a dual zone trigger input (ala TD-20) into two separate pads; but how do I split a dual zone pad (i.e.: PD-80) into two separate trigger inputs for something like the TMC-6 (which can't handle dual zone)? I tried using the same adapter but didn't seem to have reliable results. I also tried just taking Tip/GND to one input and Ring/GND to the other and it didn't work.
