Splitting keyboard to control different octaves in the same channel strip?

A single channel strip can only have one range, so duplicate the channel strip in the same patch(select the channel strip, copy by pressing command>C and paste, command>V). In instrument channel strip inspector select the layer editor tab and set the ranges of the two channel strips. The first to C1-B3 and the second to C4-C5. You can drag the ends of the layer, click on the up/down arrows, or type in the values.

Next, choose the second channel strip and select the MIDI input tab>transpose +12. That should do it.

Does this create two instances of the instrument?

Would that double the amount of samples loaded?

If you were using keys to change articulations, would one channel strip control the other? I wouldn't think.

I am trying to do a similar thing, but I want to set up the bottom few keys to control the articulations of Session Horns while i play the rest of the keyboard the the normal octave. Best I could do was trick MS into thinking the drum pads on controller were part of the keyboard, but I would like to control it from the actual keys.

Yes. Two instances of the instrument are created and the samples would be loaded twice. It's good to have plenty of RAM. They are duplicates controlled by the same keyboard, so I think you could set up articulation keys on on the lower layer and the upper layer would respond..
