DFH 1 = Thomas Haake's Sonor Set
DFH Superior (DFHS) = A buch of rock/metal oriented kits
DFH 2 = DFHS in a watered down version
DFH Superior C&V = the orange box you are talking about = more kits that are more rock/pop/vintage oriented
EZ Drummer = a midi loop quickclick demo production tool
Honest, I have it and its alright but very limited. Also it is by far the biggest resource hog out of all of them. I ended up getting superior and have not looked back.
