Yes, you can run BiaB and a DAW, CuBase in your case, simultaneously If they are using different audio interface drivers. By that I mean run BiaB using MME or WAS and Cubase using ASIO. I have done this for years with BiaB and Sonar and now with BiaB and Studio One Pro. This assumes you are using a Window's OS, I am not familiar with Macs so I don't know if that will work on them.

I hope this helps and good luck.

Whenever I get something stuck in the back of my throat, I dislodge it by drinking a beer.
It's called the Heineken Maneuver.

64 bit Win 10 Pro, the latest BiaB/RB, Roland Octa-Capture audio interface, a ton of software/hardware
