Previously made songs not working whit new keyboard

Hello everyone.
I just replace my previous keyboard Arturia Keylab Essential 49 with a new NI Komplete Kontrol 49.
All seams working fine with my Cubase Elements 9.5 on producing new songs, but when I load songs I’ve made with the previous keyboard the new one cannot interact on existing instruments nor on newly created, like is not recognized as midi input.
Anyone had a similar experience and solved it somehow?
Thanks for the support!
