I have this annoying problem in rock band 2. When i use my World Tour Drums it's almost impossible to do drum fills because half of the notes the game doesn't recognize. But when i use it in world tour there is no problems? I have tried to use my electric drumset (Yamaha DTXplorer) to eliminate all trigger problems in the WT drumset and it works perfectly in world tour/5/Smash Hits/Metallica but still doesn't recongnize all hits in Rock band 2? Is there somehow a trick to fix it?
