External Instruments not working in Cubase 12

Hello All,

I setup my OB-6 and sub37 as external instruments in Cubase 12, the same way I did in Cubase 11 however, when I play the external instruments, there is no audio coming from my synths. It still works in Cubase 11 but I need this to work in Cubase 12. Any help will be appreciated.

Adds - I don’t think my inputs are working properly either. My mic doesn’t work. I can see the meters move in the console, but no return audio in cubase. I am using a universal audio x6 interface.


Are you on Windows or Mac, please?

I use Mac. Sorry I am on my laptop account.


Make sure Cubase has enabled Mic in the System Preferences, please.

Open macOS System Preferences > Security & Privacy > Privacy > Microphone. Enable Cubase here.
