Lumatone mapping for 47edo
There are many conceivable ways to map 47edo onto the onto the Lumatone keyboard. However, as both of its fifths are about as far away from just as possible, neither the sharp or the flat versions of the Standard Lumatone mapping for Pythagorean work particularly well.
Diatonic
Flat fifth
The flat one is slightly closer, making it the patent val.
