MR816 Hardware Settings Cubase8

I recently started using an MR816CSX with cubase 8 and have noticed that the hardware settings dialog does not seem to be anywhere around - checked through the manual etc but don’t see any solution to controlling the box from within cubase - I am sure I must be missing something - apologies if it is painfully obvious :0)

It sounds fine tracking but won’t allow me to use the reverb as an effect or control the other parameters - i have even tried setting it to external fx through MR editor.

Thanks

Open the mixer and click on the Rack button.
From the dropdown choose Hardware.

Now you have the mr816 in the mixer window and can change the input flow.
