One way to map 24edo onto the Lumatone is by using the neutral third which is (one-half of the perfect fifth) as a generator, making these layouts of potential interest for [[Mohajira]] and [[Arabic, Turkish, Persian|Arabic, Turkish, and Persian]] music. | One way to map 24edo onto the Lumatone is by using the neutral third which is (one-half of the perfect fifth) as a generator, making these layouts of potential interest for [[Mohajira]] and [[Arabic, Turkish, Persian|Arabic, Turkish, and Persian]] music. | ||

The above layout has a potential disadvantage, in that each successive octave is now located substantially lower on the keyboard than the previous one, eventually requiring a jump of hand position where it wraps around to the top again. Inverting the direction of the chroma keeps octaves closer to horizontal, but going down to move pitch upward can seem counterintuitive. | The above layout has a potential disadvantage, in that each successive octave is now located substantially lower on the keyboard than the previous one, eventually requiring a jump of hand position where it wraps around to the top again.
