Lumatone mapping for 19edo

Revision as of 14:29, 23 March 2025 by ArrowHead294 (talk | contribs)

There are many conceivable ways to map 19edo onto the onto the Lumatone keyboard. Only one, however, agrees with the Standard Lumatone mapping for Pythagorean.

Diatonic

This is "Preset 4 — 19-ET Bosanquet" in the official manual.

Hanson

The 4L 3s Hanson mapping is a good option if you want to extend your range while making well-tuned chords easy to play. This mapping works especially well since 19edo can be conceptualised as a chain of essentially pure 6/5s.

Semiquartal

The 5L 4s mapping is also an excellent option, which also extends the range over the standard layout and makes the diatonic scale easier to play than on the Hanson layout.

Sensi

The Lumatone mapping for sensi is also another option, putting the notes of minor and major chords extremely close to each other:

Magic

The Magic mapping has an even wider range and makes 5-limit chords just as easy to play, but the 3L 4s scale is somewhat lopsided with its 5:1 step ratio, the chroma goes downwards in the most efficient layout, and higher limit intervals require more awkward finger stretches.
