I just bought cubase 13 and was astonished to find out that although windows sees my quad cortex with all its inputs/outputs, cubase doesn’t. Why on earth? How can this be fixed?
Hi and welcome to the forum,
Where you don’t see all Inputs/Outputs? Are you talking about audio- or MIDI Inputs/Outputs:
Maybe you didn’t install the ASIO driver for the QC?
Hi all. I figured it out. I had the drivers installed and saw all the sound interfaces from Windows sound options, but not in Cubase media.
There were two factors that helped. Cubase crashed after my attempts and I rebooted. Having quadcortex plugged in right from the beginning (before powering up the pc) seems important. After the reboot Cubase asked whether it should reset to factory settings, I answered yes, then it asked what audio interface I’d like to use, this time there was quadcortex one listed as well. Then took me some time to find the correct input/output ports (3 and 4). I ended up recording two tracks at the same time, one for left (3), one for right (4). Reassigned tracks to those specific left or right channels. And it sounded wonderful.
Hello there!
I’m facing similar problem: I am trying to use the quad cortex usb connection as an input on my Cubase 12 Artist, to record, but when I try to set it up in the “studio”, there is no sign of the quad cortex as an input option. I already navigated all the available options and… no sign of the quad cortex usb input. I even asked ChatGPT and after a lenghy debate it said that maybe my cubase version does no support that 
Any pointers as to I may be doing wrong?
Do you realise that for it to show up in connections you first must select it’s ASIO as your audio interface?
Once that’s done(assuming you installed the QC ASIO already) you should be able to select it for both in and output.
Note that windows cannot use multiple asio interfaces at one time so you can’t use QC as input and something else as output without using a third party driver to aggregate them.

Hi Grim!
Thank you for the input. Actually in windows I can chose diferent devices for input and output. From what I see it’s cubase that does not allow me to do that. I can either chose my Focusrite 2i4 driver, a generic low latency driver or the qc one and once i chose one of those in the studio setup section on cubase, when I go to audio connection, the only option i can use as input/output is the one I chose in the setup. Is that what you meant when you said “windows (cubase) cannot use multiple asio interfaces at one time so you can’t use QC as input and something else as output without using a third party driver to aggregate them”?
Yes, I’m talking specifically about ASIO drivers, windows audio doesn’t use ASIO.
It’s Cubase you can’t select them in but that’s because of Windows limitations
So if you choose the QC as your device in Cubase, you can choose QC inputs in audio connections? If yes, that’s exactly as expected.
If you want to use QC inputs and focusrite outputs simultaneously you have to aggregate with another driver (VB Audio Coconut is best option, ASIO4all is a bit simpler) which wraps windows drivers and makes themn look like ASIO to the software. You will have higher latency though.

Thank you so much for taking the time to teach me on that. I’m a longtime cubase/windows user but I kinda run away from all that technical stuff. I just want to create and record music in a setup that makes best sense and is user friendly for my needs. Using qc via audio is obviously an option but it seemed to me that usb should offer more options, including the possibility of reamping etc.
Well, I’m gonna take a look at those “agregators” to see if it’ll suit me. Thanks, again!
