Logic Pro 10.8.1 how to adjust individual drums in the mixer (and add effects etc.)

Hi all. I've downloaded the newest version of Logic Pro available for my Mac, and I cannot for the life of me figure out how to something that was very easy to do in previous versions.

In the previous version I had, I could choose a drum kit from the library, and expand its icon in the main window to reveal the separate drums. They also appeared in the mixer where I had enormous control over everything. There were also options to swap out individual virtual components with other types (vintage symbols with modern for example).

All of this appears to be gone, or if it's there somewhere, I don't know how to access it.

I called Apple support and the person I spoke to mostly didn't get what I was trying to do and we were very much at cross purposes. (He suggested I should have made a zip file of the previous version so I could have reverted back to it, as now I cannot go backwards).

I'm attaching a screenshot of something I found online which shows what I can no longer do.

Does anyone know how I can access the kind of control I once enjoyed with the virtual drum kits?

Many thanks
