Activision is aware of and is responding to issues that have been raised by purchasers of Guitar Hero: World Tour’s new drumkit in the US. Forum posters have raised concerns over drum pads not registering both hard and soft hits. Meanwhile, PS3 gamers are complaining that, despite promises to the contrary, it appears the new Guitar Hero and Rock Band peripherals are not fully cross-compatible for their console (while apparently working on the Xbox 360).
