You indicate that the Radias is connected with the USB cable.
That means that you should in the preferences window select in the drop down lists for the RADIAS MIDI connection an entry having Radias in its name.
In the screendump you show now, your focusrite device is selected. Meaning, the editor tries to reach the Radias via the MIDI DIN ports of your audiointerface.
If you don't find an entry referring to the Radias in the drop down list, then the USB driver is not properly installed. You can check this by opening the "Uninstall KORG USB-MIDI device" application. After pressing next you get a list of installed MIDI devices. The Radias should be listed there within one of the first 10 entries. If not listed and all 10 entries are occupied, you will need to uninstall first another device (freeing up a slot) and then install the Radias to occupy that free slot.
Another option is that you use the MIDI DIN cable connections of the Radias and hook them up to your focusrite and try then the editor with the settings as in your Preferences screendump of the editor. Make sure that the Radias MIDI routing is set to USB+MIDI or MIDI in that case.
Good luck!
Thanks a lot for your help. I tried what you mentioned without success

I removed the Nautilus as device to have an empty slot, but same issue. I don’t see the Radias delectable in the Midi In, at preferences. I tried reinstalling the driver, same result.
On the other hand, the midi DiN connection may work, I haven’t tried that yet, because it is complicate to undo my cable connection (I have a digital piano as main controller for the moment, not optimal but otherwise it is hard to connect later to control my piano libraries and Kawai has excellent keys), the thing is that this is not optimal for me. I also want to know if there is an issue with the midi usb slot, because this may affect the selling price. Not sure how to test it. I tried in the computer of my wife and I can see the radias there in preferences, but it doesn’t work anyway. Maybe it is because it is Windows 11 and the driver is for Windows 10.
Anyway, I really appreciate your help and time. If anybody has any idea it would be nice to read.
