I'm not sure what you mean by "arrangement area." The song page has an arrange view (where your events display) and an edit view (where you mix and process). To see the scoring for any instrument event in the arrange view, highlight the event and the clef found in the upper left of the edit view (if you want to see scoring for audio events, you have to first edit them with Melodyne, then bounce the edited event(s) to an instrument track, and then hit the clef). The "arranger track" is a separate, optional feature near the top of the song page used to designate sections of the song with names like "intro," "chorus," "outro," etc., although you can assign any names you want to different sections of your song using the arranger track. There is no way to display score notation on the arranger track. You can't even do that on the chord track (at best you'll see chord names only - which are not always accurate - but corresponding notation will not display there.) The only way I know of to see scoring is in the editor section of the song page as I described earlier. What I outlined works for the scratch pad too - highlight the event(s) you want to see and activate the clef. That's all I got. Maybe someone more versed in S1 and/or Notion will come along and provide a better answer.
