There are many conceivable ways to map 29edo onto the onto the Lumatone keyboard. Only one, however, agrees with the Standard Lumatone mapping for Pythagorean.
Diatonic
This is "Preset 7 — 29-HTT Bosanquet" in version 1.0 of the official Lumatone manual (it does not appear in version 1.21).

Pentatonic
It is possible to compress the diatonic mapping above to a pentatonic 2L 3s scale (7:5 step ratio) to get more range, at the cost of causing octaves to slope down and making the chroma run in reverse. Pedro Laranjeira Finisterra has used this mapping in Submerged (2024).

Semiquartal (Immunity)
The 4L 1s Immunity mapping works particularly well if you want a larger range, as barbados chords are tuned very accurately, gentle ones slightly less so, and 5-limit ones have far higher error, which conveniently aligns with the ease of fingering those types of chord.

Porcupine
If you do want to focus on the 5-limit, the 1L 6s Porcupine mapping makes it as easily accessible as possible for this edo and has the same range as the diatonic mapping.
