Currently in Key Editor, there is extra vertical space between B and C, as well as E and F.
This might be handy for some workflows, but it breaks visual recognition of chords because the spaces between pitches do not correspond to semitones.
In equally spaced piano roll, where each semitone has same height as others, a chord will always have same amount of empty vertical space between its notes, no matter which key it is played from. This makes it easy to recognize chords based on their vertical pattern.
In Key Editor as it is now, a major chord has a visual pattern like augmented chord when in C, F, F#, G, or like a minor chord with fifth in bass when in C#, D, D#, E, G#, A, or like a major chord with fifth in bass when in A# and B. Attached is a screenshot to illustrate this.
If any of developers see this, please consider adding the option to remove empty vertical space between B and C and E and F in Key Editor.
Equal vertical spacing corresponds to what is actually heard in 12TET and is more convenient for people coming to Cubase from other DAWs.
