Lou,
The non mumbo jumbo, ducks and chickens so I can understand it is this.

It's like having a one drawer (partition) file cabinet with different folders in it, or.....a 3 or 4 (or whatever) drawer (partitions) filing cabinet with different folders in each.

So if using one drawer as I intend to, I might have 3 folders in it....ie., styles, registrations, midis.

Hope that makes better sense.
jam on,
Terry
