There are many conceivable ways to map 31edo onto the Lumatone keyboard.

Standard Bosanquet-Wilson

This agrees with the Standard Lumatone mapping for Pythagorean. This is also "Preset 8 — 31-ET Bosanquet" in the official Lumatone manual.

Double-Bosanquet

As in Lumatone mapping for neutral thirds scales, this cuts the chromatic semitones in the "vertical" direction in half, so neutral intervals appear in between minor and major intervals. This makes neutral intervals easier to access, but puts octaves all over the place.

Anti-Double-Bosanquet

This is a flipped version of Double-Bosanquet which results in octaves being closer to horizontal. The step shape normally mapped to major seconds is here mapped to neutral seconds.

Myna

If you want maximum range while still having access to all notes, the 3L 1s Myna mapping is the most efficient one, while still giving 5-limit chords easy to play shapes.

Valentine

The Universe of Music has used the following layout, demonstrated in Her Gentle Touch (2025). In this video, even notes are mapped to red keys, and odd notes are mapped to purple keys). This layout uses the valentine as its scale of construction, inspired by the Ultra-Compressed version of the Lumatone mapping for porcupine, but even more compressed. Octaves are in horizontal rows, but stretched out over a large distance (which would be even longer if the layout were not made extremely compressed), so that the range is just slightly over 3 octaves (not counting some gamut fragments in the upper left and lower right corners), while notes are repeated multiple times vertically (at a slant), which allows an easy reach for octaves and other intervals that would require very long fingers if only available purely horizontally.
