set-up control room

I want to use Control Room in Cubase Studio 5 (with MR816x).
When I go to VST Connections to do so, there is no tab ’ Studio’, only tabs Input and Output.
What is wrong?

Not sure if there is Control Room feature in Cubase ‘Studio’ version. If quite sure it’s ‘Cubase Only’ feature, which means it’s in full version Cubase only. Anyway, if it’s there, you should find ‘Enable Control Room’ button in VST Connections window.

Just to confirm - I used Studio 5 for a couple of years. It does not have the Control Room feature.
