Real-time scale highlighting

This is a second row of keyboard notes that sits just above the main display and shows a scale for the note currently being played. This means you can see both the main song scale (loaded to the keyboard) and then the notes also filtered against the scale for the current root note. The perfect tool for improvising, this allows you to quickly identify suitable notes as you are playing.
