Due to the Lumatone wizardry of Bryan Deister, including at the larger EDO sizes, rank-3 temperament lumatone mappings are going here to avoid having other Keyboard Layout Lab pages getting too many Lumatone mappings (which causes the dreaded "template include too large" error).

Cantonismic-Werckismic rank-3 temperament Lumatone mappings

74edo (demonstrated to work but awaiting approval)

Bryan Deister has demonstrated the 7L 6s mapping of 74edo in microtonal improvisation in 74edo (2025). The rightward generator (8\74) functions as ~14/13; three of them make a classic major third ~5/4 (the cantonisma 10985/10976 is tempered out); five of them make an essentially-just undecimal subfifth ~16/11; and eight of them make a highly accurate undecimal supraminor seventh ~20/11. The upward generator (5\74) functions as ~21/20 and ~22/21 (the Werckisma (441/440 is tempered out); two of these make ~11/10; five of these make ~24/19 (which is distinguished from ~5/4); and eight of these make ~16/11. The range is about just over 3 octaves with no missing notes, and the octaves slope downward moderately, resulting in a vertical wraparound.

Compton-related rank 3 temperament Lumatone mappings

96edo (demonstrated to work)

Bryan Deister has demonstrated a mapping for 96edo in which the rightward generator is 8\96 (~18/17) as in 12edo, while the upward generator is 7\96 (~20/19), in microtonal improvisation in 96edo (2025). The range is just over two octaves, with octaves sloping away and then wrapping around; on the other hand, it is easy to play eight 12edo subsets of 96edo that are displaced slightly from each other, as if one had eight pianos (even if of rather short compass) somehow all in reach at once. (Here, note 0 is in the middle of the left edge instead of Bryan Deister's usual lower left corner, to avoid skipping some of the bottom notes in the lowest note 0 to note 0 octave.) Although not shown in the video, this mapping also enables easy glissandos diagonally up-left or down-right.

Meantone-related rank-3 Lumatone mappings

74edo (proposed and untested)

An alternate 9L 4s mapping of 74edo is worthy of consideration. The rightward generator (6\74) functions as ~17/16 and ~18/17 (the semitonisma 289/288 is tempered out); two of them make a meantone whole tone (which functions as ~10/9, ~9/8, and ~19/17 — the syntonic comma 81/80, the ganassisma 153/152, and the malcolmisma 171/170 are all tempered out); three of them make the neogothic minor third ~13/11; four of them make the classic major third ~5/4; and six of them make the lesser septimal tritone ~7/5. The down-right generator (5\74) functions as ~21/20 and ~22/21 (the Werckisma (441/440 is tempered out); two of these make ~11/10; five of these make ~24/19 (which is distinguished from ~5/4); and eight of these make ~16/11. The stacking of two or four instances of ~3/2 (43\74) and octave-reducing also yields the same results as two or four instances (respectively) of the rightward generator, making this a meantone mapping as expected for the patent val of 74edo; yet the usefulness of the down-right generator for reaching higher-limit intervals is undeniable, making this a mapping for a Meantone-related rank-3 temperament in the 19-limit that is different from Didymus. The range is about 2⅔ octaves with no missing notes, less than Bryan Deister's Cantonismic-Werckismic detailed above, but the octaves slope downward only very gently, and include a few more duplicate notes which partially alleviate vertical wraparounds (in addition to the useful temperament properties detailed above).

Unnamed rank-3 Lumatone mappings

91edo (demonstrated to work)

Bryan Deister has demonstrated an isomorphic 9L 2s mapping for 91edo in improv 91edo (2025). The range is just one note beyond 3 full octaves, with octaves sloping up mildly (which results in a wraparound of note 0). The rightward generator 9\91 is the septimal diatonic semitone ~15\14. The upward generator 4\91 is a quartertone that functions as ~32/31, ~33/32, ~34/33, and ~36/35; two of them make the minor diatonic semitone ~17/16; six of them make a near-just minor third ~6/5. The use of this generator makes this a mapping for Quartkeenlig; however, since stacking the upward generator quickly leads to wraparounds, and attempting to get the perfect fifth in 91edo with this generator yields 52\91, which is the 7edo (91bb) fifth. Therefore, this mapping really needs to be treated as a rank-3 temperament mapping; for instance, to get the patent fifth 53\92 (a mildly flat ~3/2, almost exactly 1/7-comma meantone), it is easiest to stack five rightward generators and two upward generators.

93edo (demonstrated to work)

(This mapping has been updated with the changes made to the official version by Yourmusic Productions and ArrowHead294.)

Bryan Deister has demonstrated a mapping for 93edo in microtonal improvisation in 93edo (2025). The rightward generator 6\93 represents 21/20, 23/22, and 25/24, producing a 15L 1s scale as in Valentine, although 93edo is contorted with this scale (L = 6 and s = 3) and temperament; choosing the scale 13L 3s avoids contortion, although neither the bright version (64\93) nor the dark version (29\93) of its generator maps to a convenient ratio, so the following discussion instead uses the generators for the mapping itself. Going right 2 keys makes a ~35/32 neutral second (abundantly used in the later part of the video); 3 right = ~8/7; 5 right = ~5/4; and 8 right = ~10/7. To avoid contortion, it is necessary to use a second generator, making this a rank-3 temperament mapping; the upward generator 7\93 is ~20/19; 4 steps up makes ~16/13; 5 steps up makes ~13/10, and 9 steps up (which always involves a vertical wraparound) makes ~8/5. Down-right is −1\93, enabling easy glissandos (demonstrated in the beginning of the video). In order to avoid having notes of the first note 0 to note 0 octave chopped off at the left edge, the first note 5 is placed half way down the left edge, and note 0 is 5 down-right from that. The range is just over an octave and a half, and the octaves slope from near to far.
