I have the Midi-Pro adapter for Wii that I have my electronic drumset hooked up to. When I use this with Rock Band 2, it works, except when doing a fast roll, in which case it only does a couple notes. This is not a sync problem, because this happens in the free-style drum fills. I even see the light on the adapter flash as fast as I hit the notes, so it is not a problem with the drumset. I do not have this problem in Rock Band 3, it performs the rolls as it should. Does anyone else have this problem? Is there a fix?
