The Novation Launchpad Pro's 8x8 velocity-sensitive pad grid can function as a chromatic or isomorphic instrument. ChordColor maps chord intervals onto this grid using Perfect 4ths and Major 3rds tuning layouts, with each pad colored by its interval relationship to the selected chord root. This transforms the Launchpad from a clip launcher into a visual music theory tool where you can study and practice chord shapes that translate directly to playing on the hardware.
In chromatic mode, the Launchpad's pads ascend left to right, then jump up a fourth at each new row. This is the same interval pattern as a bass guitar, which means bass players can apply their fretboard knowledge to the Launchpad directly. In Major 3rds mode, the reduced row interval creates more compact chord shapes where triads and seventh chords often fit within a 2x3 or 3x3 pad cluster.
The difference between the two layout modes becomes clear when you compare chord shapes visually. In Perfect 4ths, a major triad spans three rows. In Major 3rds, the same triad fits in two rows. ChordColor lets you switch between layouts instantly and see how the same chord rearranges itself on the grid -- helpful for deciding which mode suits your playing style and the music you are performing.
