There are many conceivable ways to map 55edo onto the onto the Lumatone keyboard. Only one, however, agrees with the Standard Lumatone mapping for Pythagorean.
Diatonic
The Standard Lumatone mapping for Pythagorean already produces a very efficient mapping for 55edo, so any alternative mapping would have to offer a compelling advantage in making certain intervals or scales easier to play. This mapping is shown in action in Bryan Deister's 55edo improv (2025).

Fibonaccic
As 55 is a fibonacci number, using the fibonacci numbers one or two steps lower in the sequence as a generator will generate a 5L 3s scale that is only slightly less efficient than the diatonic one, but makes playing xenharmonic combinations of notes together much easier.
