2B,

There are a lot of loops that are really cool, if you go to "generate a loop" in RB or insert/add a loop track in one of the slots in BIAB. Spend some time looking at the loops. There are a lot of really cool ones.

In Drums there are shakers, tambourines and so forth, lots of cool stuff.

I thought that site was cool, but for me it lacks too much control for me to use it on an actual project, though others might like it.

If I am going to to program drums I usually do it in guitar pro, and then I can be really meticulous about the percussive pieces I pick and the rhythm and so forth, and went I export the midi it produces a file that most drums synths reproduce faithfully.
