There are many conceivable ways to map 60edo onto the onto the Lumatone keyboard. However, it has 5 mutually-exclusive rings of fifths, so the Standard Lumatone mapping for Pythagorean is not one of them. Since it is highly composite, many other mappings will also fail to cover the whole gamut. Due to the very large number of notes, even those that do will have limited range.
Magic
For example, the magic mapping needs to be expanded to the 3L 13s mos, at which point it only has a range of three and a half octaves. Bryan Deister demonstrates this mapping in 60edo improv (2025).

The 3L 10s mapping is still playable and covers 5 octaves, but skips a number of chromas along the way, and this escalates with more compressed mappings.

Amity
The Lumatone mapping for Amity also suffers from chroma skips between most columns unless expanded outwards from the 4L 3s mapping to the 7L 4s one, which also makes octaves further apart vertically.

Other mappings
Other possible mappings include bleu and tritonic, but it is the fifive mapping that produces an octotonic scale which maximises range while providing access to all the notes and makes it easiest to play simple ratios together.
