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".

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 can seem counterintuitive.

The [[5L 4s|semiquartal]] layout, which uses 2.5 semitones as the generator, 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.
The semiquartal ([[5L 4s]]) layout, which uses 2.5 semitones as the generator, has a wider range, keeps octaves closer to horizontal, makes the diatonic scale relatively easy to play, and naturally puts the chroma in the right direction on the vertical axis, so it may be preferable.
