The short version is that any lane 3, 4 or 5 drum gems within the tom  
markers are considered tom drums, otherwise they are considered cymbals.   
Harmonix used this notation for pretty much all their drum charts starting  
from RB1, which is why they work with pro drums in RB3.  Customs and early  
RBN charts didn't have this information, so they were all made without tom  
markers, which is why some RBN songs in RB3 show up as all cymbals.
