Setting up Tascam FW-1884 AND FE-8s with Cubase

Hi Guys,
I’m playing around with my Cubase demo and trying to get my FW-1884 and 2 x FE-8’ss setup using the Mackie Control Protocol. I can get the FW-1884 to work pretty easily but can only get the FE-8s to replicate the 1884 rather than be 8 separate faders like an MCU extender. Can anyone shed any light on how to get them set up?
