Lumatone mapping for 130edo

From Xenharmonic Wiki
Jump to navigation Jump to search

There are many conceivable ways to map 130edo onto the onto the Lumatone keyboard. However, it has 2 mutually-exclusive rings of fifths, so the Standard Lumatone mapping for Pythagorean is not one of them. The second best 5th is diatonic, but almost as sharp as 27edo and covers less than half the notes. The third best produces 5 unconnected rings of 26edo 5ths.

There is an alternate diatonic scale that makes 5-limit chords easy to play, but it has a slight octave stretch. Since you can access nearly every note in alternating octaves, this may actually be advantageous.

Slicing both the generator and period in two will cover most of the notes in a fairly accessible way, but with range reduced to 2 & 1/2 octaves.

Harry

If you want to put the best tuned harmonies close together, the harry mapping is the most efficient one. The 14L 2s mapping covers the whole gamut with a range of 2 octaves.

Since you only need a gamut of 54 notes to hit all harmonics up to 17, you can compress it down to the 2L 6s mapping and still have access to all the well-tuned simple ratios of the edo.
