The OP has not mentioned if he is working in PianoRoll View (PRV) or track view. I can only offer suggestions for the PRV ‘cos that’s how I work.
As I went straight from 8.5 to X3 I cannot vouch for the X1 tools, but if the tools are the same then Newbie-Hobbyist’s answer is the correct one.
In case you are still a bit lost, here’s some more detail:
There are two modes for entering CCs in the Piano Roll View. One is with the Controller pane showing and the other is with it hidden. (Shift + C is the shortcut for Show/Hide Controller Pane) I prefer hiding the Controller Pane and drawing CCs on the big screen amidst the notes as follows:
Click the Notes/Velocity tab at top left of PRV and click “New Value Type”; choose a CC value from the list e.g. “1 Modulation”. Left click the smart tool in the PRV window to enter individual commands or click and drag to draw. Like Newbie Hobbyist said, you get more detail if the Snap feature is off.
(The shortcut for Snap on/off is N)
If you prefer to work with the Controller Pane open: You should see the default name “Velocity” at the left of the pane strip with a down arrow next to it. Click on the down arrow, then click “New Value Type” and follow the previous instructions.
