AKAI MPK Mini

I am running 13 Pro on Windows 11. I am new to midi. I felt the MPK MINI was a good place to start. This is plugged in via USB so I am not using any interface unless recording vox, guitars ect. I need help. I have plugged the MINI in and Cubase seems to recognize it. Also, thinking I had stepped away recording I sold my monitors a while back so I will be monitoring through the head phone port in my PC. Anyone out there throw me some help? Important info. I have not used Cubase since 7 so 13 pro seems different to me. I did not use MIDI then either.
