Need help Studiologic SL88 i Cubase 11

[Jankomuzyk]

I have a problem with SL88 Studio and Cubase 11 pro, Windows 10 pro operating system. The keyboard is sending data but the virtual instruments are not responding. I do not know what to do. they just don't play. I've been struggling with this for days. Also, the keyboard doesn't send data via USB, only via MIDI1 and 2. When I turn on just virtual instruments without a DAW, everything is fine.
