There are many conceivable ways to map 70edo onto the onto the Lumatone keyboard. Only one, however, agrees with the Standard Lumatone mapping for Pythagorean.

Diatonic

However, due to its size, this mapping does not cover all the notes. In addition, the best approximation to 5/4 is a quadruply augmented or pentuply diminished 7th, which is impossible to play with the root note of the chord. In most cases it will make more sense to use the c val, where it is a diminished 4th.

Diaschismic

The 2L 8s mapping covers the whole gamut and makes harmonics easier to play together, although some of the higher ones are less efficiently mapped than in 58edo.

Antidiatonic

The 7L 2s mapping generated by 31/70 covers all the notes with even fewer repeats, but does not put the harmonics as close to each other.
