Mackie MCU Pro and two XTenders mirroring

[animix]

I am running DP8 on a Win 7 64 bit DAW (i7 960-12G RAM). The audio interface is an RME MADI PCIe/FX card. I am new to DP and this is my first post here. I am trying to configure my control surfaces. At this point the extender surfaces are mirroring the main controller. I have basic functionality of the transport controls. I haven't moved beyond that at this point. In the setup window I am seeing 16 drivers for each of the three control surfaces. I have noted the L>R instructions as relate to the channel order. Is there a particular driver choice (of the 16 available per control surface) that I should be using? I have done a search of this forum and noted that there are others having issues with the MCU at this point. Just wondering if anyone has achieved functionality with multiple controller surfaces yet. Thanks in advance for any feedback.

This is an old thread, but, are you still having a problem?

I remember it being tricky in Control Surfaces.

It may be different for Windows though.
