Cubase registers my input signal, but I can't record.

I have just set up all my stuff, but probably did it wrong. I’m at the point where I can plug my guitar into the interface and get a signal, and I can hear it in the monitors too. But when I click record, I just get a flat line. Nothing records.

What am I doing wrong?

Apart from that you are not giving any useful info - you certainly haven´t set up your at least connections correctly.


Are you using a Mac? If so, it’s possible that you don’t have permission to use the “microphone” which is Apple’s way of confusing people … what they really mean it the audio interface. To check this, go to System Preferences/Security and Privacy/Privacy and click on Microphone in the left pane. The right pane should show all apps that use the “Microphone” … make sure that Cubase is checked. Should work after this.


I think, then he wouldn’t even hear the signal while monitor.

Make sure Cubase has enabled Mic in the System Preferences, please.
Open macOS System Preferences > Security & Privacy > Privacy > Microphone. Enable Cubase here.
