The problem is not the notes, but the rhythm. Piano roll is based on squares that represent the duration of a note (based on pianolas), but the kids learn to read music in a traditional way, which is focused by the way in the diatonic scale. However, I just though it was a good idea to fill the gap between the classically trained musicians and the non-classically trained, and make this technology more appealing for the kids from the music schools.
And if they use Notion, then they don't learn to work with the DAW and the problem goes on. The kids from music schools use Dorico, Sibelius, Finale or Musescore (and Notion, of course), but all of these (Notion included) are focused on engraving and not on producing music. That's why I asked.
