Lumatone mapping for 51edo
There are many conceivable ways to map 51edo onto the onto the Lumatone keyboard. However, it has 3 mutually-exclusive rings of fifths, so the Standard Lumatone mapping for Pythagorean is not one of them. You can use the b val, which can be interpreted as either mavila or undecimation, but is not a particularly great tuning for either.

Instead, it is probably better to use one of the mappings that reaches the perfect 5th in three generator steps. Of these, the slendric mapping has the greater range.
