There are many conceivable ways to map 24edo onto the Lumatone keyboard. However, the Standard Lumatone mapping for Pythagorean cannot be used because 24edo is not generated by fifths and octaves, since only a 12-note subset of it is reachable that way.
The official Lumatone manual, however, contains the following mapping of 24edo as "Preset 6 — 24-ET Isomorphic". Note that it is a rotated version of a Lumatone mapping for neutral thirds scales.

However, this means each octave is 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 makes for less intuitive play.

The semiquartal layout has a wider range and keeps octaves closer to horizontal, while naturally putting the chroma in the right direction on the vertical axis, so it may be preferable.
