As I sit here typing this, every minute or so, I hear a very faint splash cymbal. That's the #4 tom rim. From time to time, I get the #3 rim, and more rarely the #3 head. Those three triggers just generate random little signal blips every so often, for no discernible reason.
I asked Alesis about this, and never heard back. I spent some time researching how piezos work, and I can't think of any reason for this. I diddled and piddled and twiddled all kinds of settings in the module, and didn't get anywhere. I did some research to see if this is a common problem, and didn't really turn up anything.
Since I finally got around to joining this forum where I've been lurking for a month or two, I decided I might as well ask here. Maybe someone knows how I can give these triggers the exorcism they need.
