Where are the MIDI CC lanes in Cubase?

I’m trying to get an articulation to change in Kontakt in Cubase but I need to access the MIDI CC lanes to input the data.
Where is it?
RS.

Double click on the MIDI part in question to open the editor. The CC lanes are at the bottom. It is probably defaulted to velocity but you can select others or add more… Search Controller Lanes in the manual for more details.
