Wavelab 7 & Cubase 7 together

How can I using Cubase 7 together with Wavelab 7?
I want to use Cubase like sequencer & recorder, together with sound analyzers of Wavelab 7!
My friend has Pulsar sound card and he said me that all works fine.
I have RME sound card (Multiface) and I don’t know what configuration of routing can I adjust?
Is it possible with RME sound cards, or only with Pulsar sound card, and its specifical ruoting scheme?

Not quite sure what you want to do, or why, but you could route via TotalMix … although for realtime analysis, you’ve already got DIGICheck.
