Activision is replacing my Band Hero Drum kit because basically right out of the box the drum pads were randomly not registering hits. First noticed it trying to do a long drum roll on the red pad. Tested in both Guitar Hero and Rock Band games and experienced the same problem, even after getting the MIDI USB adapter and shifting the sensitivity. Has anyone else experienced this issue? I'm hoping that I just got one bad item off the production line, and they're not all bad like with first shipments of other game peripherals, because then this first warranty exchange would just be a waste of time. I got these drums because the cymbals are a hell of a lot more durable than the original Guitar Hero World Tour drums, and they have the best compatibility for Wii--everything except Rock Band 1.
