Unlike traditional keyboard, Isotope's isomorphic grid layout is based on mathematical and geometrical properties of sound itself. When you play it, it's much more intuitive. When you want to learn about music, it shows how notes relate to one another. # Isomorphic Keyboard - If the interval stays the same, the form of your hand stays the same.
