Hi,
There was probably Cubase 9. But thanks to the Steinberg Grace Period, you can upgrade for free. Use your Cubase 9 activation code, and activate Cubase 9. Then you will be informed about Cubase 9.5 license update. Download (activate) Cubase 9.5 license. Then the Cubase 9.5 installer appears in your MySteinberg account, and you can download it.
