Yeah, I get that. The module can handle the capability. The wiring harness can handle the capability. It's just that Alesis didn't include tom pads that can handle the capability. I just found that kind of funny.
I seriously doubted I would use rim sounds on the snare, so I am using the snare pad in the first tom position, and using the rim there as a trigger for some programmed sounds in my DAW software.
I guess they just included the information in the event that people wanted to replace their single zone pads with dual zone pads, which I have started doing, so I can essentially add sounds the kit won't to support in its off-the-shelf configuration. This will give me a lot more flexibility in the sounds I can get without having to switch kits in the DAW software. That software is also allowing me to have a China cymbal, which the Nitro module doesn't seem to have.
Be well
