Chord palette + circle of fifths + chord track
With this beautiful grid, it will be nice to have a chord palette (with chords related to the scale chosen in the deluge) + circle of fifths for transposition. Even a master chord track to being able to transpose- re harmonization of all the tracks ( like the master track of the teenage engineering op-z or the squarp pyramid).
Some kind of chord stuff and harmony tools, can enhance the music creation and to kill the writer's block. Having a big grid, makes easy to implement some kind of chord palette.
