The options to force notes to conform to chords/scales are found in the Track Inspector’s Chord tab. Now the note colors will indicate if it is in the scale but not the cord, in the chord but not the scale, in both the chord and scale, or not in either. Now if you are in the Key Editor you can set the Event Color to be the Chord Track instead of the default Velocity.
To do any of this you need to add a Chord Track and put scale and/or chord symbols on it. You can also force notes you play to be forced to the scale/chords. You can also see the notes color coded to show if they are in the scale and chords or not. No you can’t restrict notes input by hand in the Key Editor to only the scale, however you can force it conform to the scale and/or chords after the fact. I have seen a few threads asking for the selected notes to light up in the piano roll and false notes to be silenced in very old feature request threads (2012) so I guess you must have added this way back.
I guess I just have not found the right button to press, right? I have been searching in the manual and in this forum for a way to restict the piano roll so I can only enter notes in the selected scale.
