There are many conceivable ways to map [[140edo]] onto the [[Lumatone]] keyboard. However, the Standard Lumatone mapping for Pythagorean is not one of them because there are two mutually-exclusive rings of fifths. You can use the b val fifth, which is slightly flatter than [[19edo]] and an excellent generator for [[marfifths]]. Note that due to the size of the edo, this does still cover less than half of its notes, but you can access the better third and fifth by zig-zagging three steps down from the slightly flat ones, making near just 5-limit chords accessible in quite a few keys.

If you want to be able to access the full gamut, the [[15L 4s]] [[kleismic]] mapping is probably the most efficient and intuitive layout, although it doesn't even reach two octaves.
