Watched another Video of the Sequins mode (or App or how it is called)

What I still don't get. How do you put in the notes for the next step? Do you really have to select the Notes with
these Numbers? It can't imagine thats the only way.

Does it not trigger the Note from the Next step and you can select the pitch by dialing the knob? (like moving
the slider on the Pittsburgh Sequencer)
