Editor Scale
The default accidental notation system in score editors uses sharps. This system can be modified, to a certain extent.
 | The Editor Scale dialogue window offers a limited number of enharmonic accidentals, based on the standard twelve semitones notation. This especially makes sense when using a tonal or modal semitones scale pattern. To specify a scale
|
To assign an enharmonic accidental to a note, Ctrl / right click on it and select a menu item.
Modifications of the default scale are displayed by the dialogue window. Click on Default to reset the default scale. |  |
Cadences, Degrees and Figuring

The analysis takes place as chords are being edited, provided OM can recognize a listed chord and chord progression. |
Modulation
Modulations can be specified textually in the score editor.
|  |
 | OM displays the modulation but it doesn't automatically adapt the key signature or accidentals to the new tonality. |
