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