Complaints have begun to surface about the "velocity sensitivity" of the kits, according to 1Up, meaning that hard hits on the drums only register as soft hits, and some owners are saying that drum pads or cymbals have quit working altogether. In response, Activision has released a statement claiming that the defects should be limited to only early production runs of the kits, and that a fix is on the way.
"We have learned that certain drum kit controllers manufactured for Guitar Hero World Tour have sensitivity issues," the company said in the statement. "We believe that these controllers are limited to ones in the earlier manufacturing stages. While we believe that this was an isolated manufacturing issue, we are stepping our efforts to randomly test our drum kit controllers so customers can be assured they work properly. In the event any consumers do experience problems with their drum kit controllers associated with sensitivity issues, Activision will soon be offering a drum tuning kit that will enable players to fully optimize their drums."
"Our goal would be to immediately address any hardware issues Guitar Hero World Tour players have with the game," the statement continued. "Consumers should visit the Activision Publishing customer support website at www.activision.com/support website or call 310 255-2050 in the U.S. where a customer care representative will assist them."
No word yet on what a "drum tuning kit" actually is, or how it will help people whose drum kits have stopped working entirely, but no doubt all will be made clearer in the coming days.
