you can plug your dual zone cymbal onto one input of your i/o alesis…  you have to setup the input… (the module input has to be setup for piezo/piezo pad…check your user’s manual)   you have to use a stéreo cable (three wires )and a stereo jacks

tip of the jack : ceramic part of the bow piezo
sleeve            : yellow part of the bow and bell piezo
ring               : ceramic part of the bell piezo

you can invert the wires on the bow piezo (tip : yellow part of bow piezo and sleeve to the ceramic part of the bow piezo) if you feel it works better like that    (roland pads are wired liked that for their dual pad and cymbal zones)

it should work like that…
