SpectralLayers activated from Cubase --> no Editor

I use SpectralLayers Go 11.0.40 embedded in Cubase 12 Pro.


Assigning one audio event to the SpectralLayers extension does not open the SpectralLayer window in Cubase Editor, instead the Cubase Editor just shows at the right upper corner “remove event” and “add event”. Yet the extension seems to be rightfully assiged to the audio event, as shown by the icon in the selected region.
Can anyone advise on how to get the actual SL editor shown up? Thx!

You need Cubase Pro 14 in order to use SpectraLayers Go 11.0.40.
With Cubase Pro 12 you can only run SpectraLayers One 9 (or SpectraLayers Pro 11.0.40 if you buy a Pro license of course).
