Thanks for your reply Hellfire. I did open up the cymbal no problem, checked all the connections and they seemed fine. Then, just to be on the safe side, I unclipped the mylar switch ends and put them back together. Still the same.
I then performed factory reset of the module and reuploaded the most recent firmware (all the steps incl triggers, rom etc.) That didn't help either.
Do you think there is a way of fixing that without replacing? I can certainly fix the PCB, try and source the parts and replace them. I tried looking for the Alesis DMPad 16'' 3 zone ride but on Alesis website it says it's been discontinued and I could not find another one online.
Not sure if this isn't a problem with the jack socket too. When I unplug the jack from the brain just slightly so that only one area on the jack sleeve in connected the bell works.
Any ideas?
