Inverting the direction of the chroma keeps octaves closer to horizontal, but going down to move pitch upward makes for less intuitive play.

There are many conceivable ways to map 24edo onto the Lumatone keyboard. However, the Standard Lumatone mapping for Pythagorean is not one of them because there are two mutually-exclusive rings of fifths.

The official Lumatone manual, however, contains a rotated version of a Lumatone mapping for neutral thirds scales as "Preset 6 — 24-ET Isomorphic".
