Getting Audio output from Sonic SE2

I’ve just started using Sonic SE2 within Cubase and wanted to route the audio output from Sonic into an audio track but cannot find any way to do this as the Cubase track inputs will not recognise any of the Sonic outputs. Although I am getting an audio output from Sonic at my USB connected desk, this is not being recognised within Cubase although Audio inputs from the desk are being recorded successfully.
