Lumatone mapping for 55edo
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).

Tetracot
The 6L 1s (Tetracot, 55c val) mapping also provides a heptatonic scale that gives you access to all the notes in the gamut in an intuitive way without any backtracking. However, the 7L 6s MOS has a 7:1 step ratio, making it quite lopsided.
