Free version of Cubase ai?

i bought the Steinberg 2 channel ur22c online and it came with a free version of Cubase AI or LE i honestly cant remember but if someone has had this same buy can you explain what I’m am supposed to download as far as spectra layers, what version of Cubase AI is it 11 or 12? i should have done this a long time ago being as i got this interface around 2020 and i was using the reaper program at the time and idnt undertsnad everything about the DAW and didnt want to mess anything up but now i realize that cubase can be a great little studio and the free AI verison

If you have the activation code or the Download Access Code that came in the box, try to download the latest version using the Steinberg Download Assistant | Steinberg

Otherwise Steinberg Support will provide you with a license. (They are out till after the new year.)

I don’t know if Spectralayers is included.

SpectraLayers is only included in Cubase Pro and Cubase Artist, the Cubase versions with ARA2 support.
