I have BB 2008.5 megapack and thinking of upgrading to either the new pro or megapack. I am trying to understand what comes in the new megapack, and due to my poor understanding of reatracks and realdrums, I am not sure what they mean when they say, for example, "70 realtracks in 19 bands and realdrums sets 1 to 6". How do styles/realtracks/realdrums relate to each other, and to the "sets" they sell of them. Is it that only some styles use realtracks, and realdrums, but you can substitute realdrums in old styles (but not realtracks)?

In the old megapack install, I seem to have styles disks up to 77 (all of them?).

Also, in my old megapack I have

- realtracks1.exe
- realtracks2a.exe
- realtracks2b.exe
- realtracks3.exe
- realtracks4.exe
- realtracks5.exe
- realtracks6a.exe
- realtracks6b.exe

- realdrums1-6.exe
- realdrums4.exe
- realdrums11.exe
- realdrums14.exe
- realdrums20.exe

Seems like I might not be getting much more (maybe even less drums) in the new megapack?
