=== 39edo (demonstrated to work) ===

[[Bryan Deister]] has used a [[Porcupine]]-inspired layout for [[39edo]], as demonstrated in [https://www.youtube.com/watch?v=XLRaG_pBN7k&lc=UgwfjZwncsryQjeNUg14AaABAg.AHVkw8aNSEGAHZU_J2qOPM ''39edo jam''] (2025). To take advantage of the fact that 39edo is at the intersection of [[Augmented]] and [[Immunity]], the rightward generator is 5\39, half of a [[6/5]] minor third as [[12/11]] ~ [[11/10]] (but much closer to 12/11). This enables a MODMOS derived from [[1L 6s]] by shrinking the large step from 9\39 to 8\39 and expanding one of the small steps from 5\39 to 6\39, to enable chords such as 12/11 (somewhat sharp, at 5\39) - 6/5 (slightly flat, at 10\39) - [[11/8]] (near-just, at 18\39) - [[3/2]] (mildly sharp, 23\39) - [[18/11]] (moderately sharp, at 28\39) - [[9/5]] (near-just, at 33\39). Playing this chord uses almost the same geometry of depressed keys as that for playing a diatonic scale in a diatonic mapping (but has a very different sound effect), save when proceeding to the next octave. The range is slightly over 6 octaves overall (which slant moderately downwards), but with the first and last octaves missing some notes due to clipping in the upper left and lower right corners of the layout.

== ~~Compton~~-~~related rank~~ 3 temperament Lumatone mappings ==

== Augmented (Triforce) + Bohpier Lumatone mappings ==

=== 33edo (demonstrated to work) ===

[[Bryan Deister]] has demonstrated two mappings for [[33edo]] that function for the temperaments [[Augmented]] ([[Augmented family#Triforce|Triforce]], 33d val, [[3L 3s]] scale with 7:4 step ratio) and [[Bohpier]] (33cd val, [[8L 1s]] scale with 4:1 step ratio). The down-right (forward chroma version) or rightward (reverse chroma version) generator is a somewhat flat Alpharabian tendoneutral second ~[[12/11]] which can be stacked to get several consonant intervals; however, some of them map inconsistently. Two of these generators make a near-just neogothic minor third ~[[13/11]], mapped consistently. Three of these generators make a near-just septimal major third ~[[9/7]] by sound, but the mapping only works if 9/7 is constituted as (3♭ × 3♯) ÷ 7 or as 9 ÷ 7♭ (33d val). Four of these generators make a near-just lesser septimal tritone ~[[7/5]], mapped consistently ([[patent val]] or 33cd val). Six of these generators make a flat classic major sixth ~[[5/3]] by sound, but the mapping only works if 5/3 is constituted as 5♭ ÷ 3 (33c val). Seven of these generators make a near-just classic minor seventh ~[[9/5]] by sound, but the mapping only works if 9/5 is constituted as (3♭ × 3♯) ÷ 5 or as 9 ÷ 5♭ (33c val). The range is a bit over six octaves in the forward chroma version or five octaves in the reverse chroma version; in both cases, the octaves slope moderately downwards resulting in a vertical wraparound.

== Bidia + Diminished + Charismic + Semitonismic Lumatone mappings ==

=== 56edo (demonstrated to work) ===

[[Bryan Deister]] has demonstrated a [[4L 4s]] (9:5 step ratio) mapping for [[56edo]], in [https://www.youtube.com/watch?v=xkfao6yGKGE ''Curious Light - DOORS (microtonal cover in 56edo)''] (2025). Right + down-right divides the octave into slices of 14\56; as an interval in its own right, this is the same as the minor third of [[12edo]], which functions as ~[[19/16]] and ~[[25/21]] (both being near-just). Down-right alone is 5\56, which is the [[Normal forms#Minimal_form|minimal form]] generator for [[Bidia]]; it functions as the classic diatonic semitone ~[[16/15]], the large septendecimal semitone ~[[17/16]], and the small septendecimal semitone ~[[18/17]], meaning that the charisma [[256/255]] and the semitonisma [[289/288]] are both tempered out; two of them make a rather sharp whole tone ~[[9/8]]; three of them (passing the quarter-octave) make a mildly sharp classic minor third ~[[6/5]], although the afore-mentioned quarter-octave (12edo-style) minor third is easier to reach; in contrast, the near-just classic major third ~[[5/4]] is very easy to reach with just two moves rightwards, and a down-right move from this reaches the moderately flat fourth ~[[4/3]]; two more down-right moves reaches the rather sharp fifth ~[[3/2]]. The efficiency is almost as good as that of the diatonic mapping, with no missed notes and one repeated note per octave; the overall range is somewhat under five octaves, with no notes chopped off by the left and right edges before reaching the end of overall range. The cost of this is that octaves slant downwards.

== Biyatismic Lumatone mappings ==

=== 68edo (demonstrated to work) ===

[[Bryan Deister]] has used a [[Biyatismic clan#Zeus|Biyatismic (Zeus)]] layout with a [[7L 1s]] scale (9:5 step ratio) for [[68edo]], as demonstrated in [https://www.youtube.com/shorts/CO1AslAu9E0 ''microtonal improvisation in 68edo''] (2025). The rightward generator 9\68 is a combination of the Alpharabian tendoneutral second ~[[12/11]] and the undecimal submajor second ~[[11/10]], and two of these make a near-just classic minor third ~[[6/5]], with the biyatisma ([[121/120]]) being tempered out. The chroma of the scale (4\68, upwards on this layout) is the near-just diptolemaic chromatic semitone ~[[25/24]], and is convenient to use as a second generator (even though such is not required to avoid [[contorsion]]) to access other consonant intervals quickly, although sometimes with strange preferences built in — for instance, the septimal whole tone ~[[8/7]] is much easier to reach (at 13\68) than the Pythagorean whole tone ~[[9/8]] (which requires a substantial vertical reach at 12\68), while the septimal minor third ~[[7/6]] (at 15\18) is a much longer vertical reach than the classic minor third ~6/5 (at 18\68), and the septimal major third ~[[9/7]] is a much longer vertical reach (at 25\68) than the classic major third ~[[5/4]] (at 22\68). Fortunately the fourth (~[[4/3]], at 28\68), the Axirabian paramajor fourth (~[[11/8]], at 31\68), the Axirabian paraminor fifth (~[[16/11]], at 37\68) and fifth (~[[3/2]], at 40\68) are all easy to reach as long as they do not go through a vertical wraparound (as happens to the fourth in the bass octave). The range is four octaves plus two notes, and octaves slope upwards — not severely, but a vertical wraparound is unavoidable if note 0 is placed to get complete octaves as defined to reach from note 0 to note 0.

== Blackwood + Diminished Lumatone mappings ==

=== 20edo (demonstrated to work) ===

[[Bryan Deister]] has used a [[Diminished]] [[4L 4s]] (4:1 step ratio) mapping for [[20edo]] that also functions as a [[Blackwood]] mapping, as demonstrated in [https://www.youtube.com/shorts/bqYA9flwL_g ''20edo prelude''] (2025). In this mapping, the octave can be interpreted as being divided into five parts (Blackwood temperament) or 4\20 or four parts of 5\20 (Diminished temperament). Octaves slope, as expected for a Blackwood mapping, but with plenty of repeated vertical notes, and the range is a bit over 5½ octaves.

== Compressed Skwares (Fibotonic) Lumatone mappings ==

=== 20edo (demonstrated to work) ===

[[Bryan Deister]] has used a compressed [[Skwares]]) [[2L 1s]] (7:6 step ratio) mapping for [[20edo]], as demonstrated in [https://www.youtube.com/watch?v=BFUTeFs7Ycg ''20edo groove''] (2025). In the version of Skwares used for this, instead of substantially sharpening the undecimal major third ~[[14/11]] (or even a septimal major third ~[[9/7]]) to get a diatonic fourth ~[[4/3]] (by stacking and octave-reducing four generators), the undecimal major third (7\20) is near-just, and the fourth is very flat at 480{{c}} (corresponding to the Blackwood sharp fifth at 720{{c}}). Octaves are nearly level (sloping down very gradually), and the range is a bit over 11 octaves, which suggests dividing the keyboard into zones for different instruments.

== Cantonismic Lumatone mappings ==

=== 64edo (demonstrated to work) ===

[[Bryan Deister]] has demonstrated a [[Cantonismic]] (flipped and rotated diatonic) mapping of [[64edo]] in [https://www.youtube.com/shorts/ag1FbgAuR6I ''microtonal improvisation in 64edo''] (2025). In this mapping, the rightward generator 7\64 is mapped as a slightly sharp tridecimal supraminor second ~[[14/13]], and the [[cantonisma]] (10985/10976) is tempered out, so that three of them make a fairly sharp classic major third ~[[5/4]], and eight of them make a near-just undecimal neutral seventh ~[[11/6]]; note that apart from ~5/4, these ratios depending upon partial cancellation of errors in the harmonics as represented by 64edo. The rightward generator is actually the short step of the easiest scale to play on this layout (provided that the scale is positioned not to go through a vertical wraparound), with the down-right step being 10\64, which corresponds to the [[Patent val|patent]] (not [[direct approximation]]) whole tone ~[[9/8]], thus enabling a rotated diatonic scale. Octaves alternate between far and near superimposed on an overall slant away over the range of three whole octaves (having no missing notes) plus a fourth octave that has some notes chopped off by the right edge, and some fragmented note sequences in the upper left and lower right corners. A side effect of the alternation of octaves is that accessing the fourth and fifth can be easy or hard depending upon not only the root note, but also the octave — for instance, in the middle and mid-right octaves, 27\64 and 37\64 are both easily reached from 0\64, but in the second full octaves, they same interval requires a long finger stretch if the root note is greater than 0, and the rotated diatonic scale goes through a vertical wraparound (and moving note 0 would simply cause other root notes to have the same problem in some of the octaves).

== Diaschismic + Charismic + Semitonismic Lumatone mappings ==

=== 58edo (demonstrated to work) ===

[[Bryan Deister]] has demonstrated a [[2L 6s]] (14:5 step ratio) mapping for [[58edo]] in [https://www.youtube.com/shorts/7gkRyld5OU8 ''Waltz in 58edo''] (2025). The rightward generator 5\58 functions as the classic diatonic semitone ~[[16/15]], the large septendecimal semitone ~[[17/16]], and the small septendecimal semitone ~[[18/17]], meaning that the charisma [[256/255]] and the semitonisma [[289/288]] are both tempered out. The rightward generator is also the [[normal forms|minimal form]] of the [[Diaschismic]] generator, and indeed the [[diaschisma]] 2048/2045 is also tempered out. This generator makes a slew of intervals of reasonable prime limit that are not far from just: two of them make a near-just whole tone ~[[9/8]]; three of them make a mildly flat classic minor third ~[[6/5]]; four of them make a mildly flat undecimal major third ~[[14/11]]; five of them make a near-just classic acute fourth ~[[27/20]]; six of them pass the [[semioctave]] to make a slightly flat greater septimal tritone ~[[10/7]]; seven of them make a slightly flat septimal superfifth ~[[32/21]]; eight of them make a slightly flat tridecimal supraminor sixth ~[[21/13]]; nine of them make a near-just septimal major sixth ~[[12/7]]; and ten of them make an extremely accurate undecimal supraminor seventh ~[[20/11]]. Other common intervals such as the moderately sharp (although high in relative error) classic major third ~[[5/4]], the near-just perfect fourth ~[[4/3]], and the near-just perfect fifth ~[[3/2]] are in very easy reach of the chain of rightward generators, and not very distant from the root note. This may be sufficient compensation for the reverse chroma and the range of only three full octaves (which slope only slightly upward), with large partial octaves being chopped off by the upper left and lower right corners.

=== ~~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 [https://www.youtube.com/shorts/8xqjUkuZFaI ''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.~~

=== 90edo (demonstrated to work) ===

[[Bryan Deister]] has demonstrated the [[Diaschismic]]-[[256/255|Charismic]] [[10L 2s]] mapping for [[90edo]] (with 8:5 step ratio), in [https://www.youtube.com/shorts/0j33e4F-4jY ''microtonal improvisation in 90edo''] (20025). The rightward generator 8\90 is a semitone that functions as both ~[[16/15]] and ~[[17/16]] (the charisma [[256/255]] is tempered out). Splitting the octave in half (the [[diaschisma]] 2048/2025 is tempered out) enables this generator to produce the mapping without [[contorsion]]. The range is about 2⅔ octaves with no missed notes, with a mild upward slope.

== Diatonicized Chromaticism via Rotated Antidiatonic ==

=== 37edo (demonstrated to work) ===

[[Bryan Deister]] has demonstrated a rotated antidiatonic ([[2L 5s]]) mapping in [https://www.youtube.com/shorts/e7dLJTsS3PQ ''37edo''] (2025), using the Mavila (sub-)fifth (21\37) as a generator. This yields a range of over five octaves, although the note 0 positions alternate between middle and near/far. (In the demonstration video, active keys on the Lumatone are cut back at both the left and right edges to yield exactly five octaves.) With this mapping, notes of the [[11L 2s]] scale line up in pairs of row segments (of 6\37 offset from each other by the large MOSstep 3\37, and cut by the small MOSstep 2\37), which may make this mapping attractive for users wishing to play [[Ivan Wyschnegradsky]]'s Diatonicized Chromatic scale in a tuning system different from [[24edo]], while still retaining respectable (though not full piano) range.

== Godzilla-related rank-3 Lumatone mappings ==

=== 62edo (demonstrated to work) ===

[[Bryan Deister]] has demonstrated a [[Godzilla]] Lumatone mapping for [[62edo]] in [https://www.youtube.com/shorts/UerD0NqBbng ''microtonal improvisation in 62edo''] (2025), with scale [[5L 4s]] with 10:3 step ratio, which also has easy provision for dividing the near-just septimal minor seventh ~[[7/4]] (50\62) into five equal parts each functioning as a meantone whole tone (~[[9/8]], ~[[10/9]], and ~[[19/17]]) (10\62 is right by one key), which is naturally useful in its own right for mixing the common practice sound in with the xenharmonic sounds. A logical implication of splitting the ~7/4 into five meantone whole tones is that the near-just classic major third ~[[5/4]] is very easily accessible as two of these divided generators, and the only slightly flat lesser septimal tritone ~[[7/5]] is easily accessible as three of them. As convenient as this rightward generator is, it would produce a contorted mapping if not for a second generator; the upwards generator 7\62 is convenient for this as a a tridecimal neutral second that functions as both ~[[12/13]] and ~[[13/14]] (the buzurgisma/dhanvantarisma [[169/168]] is tempered out); backing off from ~7/4 by two of these generators gives the fifth (the flat ~[[3/2]] shared with [[31edo]]), while backing off from ~7/5 by two of these generators gives a moderately flat classic minor third ~[[6/5]]. Octaves slant down moderately, and the range is just under 4⅓ octaves with no missed notes and no repeated notes.

== Magic (Divination/Soothsaying) related Lumatone mappings ==

=== 82edo (demonstrated to work) ===

[[Bryan Deister]] has demonstrated a [[8L 6s]] mapping of [[82edo]]. Being even 82edo supports a [[semioctave]] period, with the diagassormisma ([[3042/3025]]) being tempered out in the [[patent val]] or the kalisma ([[9801/9800]]) being tempered out in the 82e val; this enables it to use the (somewhat sharp) septimal major third ~[[9/7]] (as 30\82) as a generator (which would be [[contorted]] down to [[41edo]] with a whole octave period), in a temperament like [[Magic family#Soothsaying|Soothsaying]] or [[Magic family#Divination|Divination]], but using the septimal major third as a generator instead of the classic major third ~[[5/4]]. (Since 82edo also supports actual Soothsaying in its patent val and actual Divination in its 82e val, it is also possible to use generator 26\82, the somewhat flat ~[[5/4]], although the resulting [[6L 4s]] scale is a bit more tricky to play using this layout.) The range is about 2¾ octaves with no missed notes, and the octaves slant down.

== Meantone Lumatone mappings ==

=== m-Chromatic Lumatone mappings ===

==== 81edo (demonstrated to work) ====

[[Bryan Deister]] has demonstrated the m-chromatic ([[7L 5s]] with 8:5 step ratio) mapping for [[81edo]] in [https://www.youtube.com/shorts/5O6Cyawjkd8 ''''microtonal improvisation in 81edo''] (2025). The rightward generator 8\81 functions as ~[[15/14]] and ~[[16/15]]; six of them make the alternate sharp fifth. The down-right generator 5\81 functions as ~[[23/22]] and ~[[24/23]]; two of them make an Alpharabian tendoneutral second (~[[12/11]]); four of them make the near-just octave-reduced 19th harmonic ~[[19/16]]; eleven of them make a near-just classic minor sixth ~[[8/5]]. The patent fifth 47\81 is four rightward generators plus three down-right generators. All that said, the patent fifth itself works perfectly well as a generator of the 7L 5s scale, as well as for the entire layout, as befits (rank-2) [[Meantone]], so that the use of dual generators is a matter of convience rather than a requirement. The range is just over three octaves, with no missed notes, and the octaves slant down moderately.

== Reversed-Chroma Compressed Tetracot Lumatone mappings ==

=== 75edo (demonstrated to work) ===

[[Bryan Deister]] has demonstrated a compressed [[1L 5s mapping of [[75edo]] in [https://www.youtube.com/watch?v=5-G2KkYfKLs&list=WL&index=343&pp=gAQBiAQB8AUB ''microtonal improvisation in 75edo''] (2025-06-22). This combines the temperament of [[Tetracot]] with the idea of the compressed [[Lumatone mapping for Porcupine]], by reversing the chroma. (This also contains the Tetracot [[6L 1s]] scale, but playing that scale in this layout requires backtracking.) This expands the overall range to more than five octaves, but too much so for anything so large as 75edo, thereby causing missed notes (although it demonstrates how such a mapping could shine for a smaller EDO or a hypothetical XL-sized Lumatone that has room for all of the notes).

== Superlimmal Lumatone mappings ==

=== 80edo (proposed and untested) ===

Proposed and untested [[5L 7s]] [[Canousmic_temperaments#Superlimmal|Superlimmal]] mapping for [[80edo]]. This layout using the generator 9\80 (which functions as ~[[13/12]], ~[[14/13]], and ~[[27/25]]) has very efficient use of keys (with no missed notes and just one repeated note per octave), but octaves slope down severely and wrap around even within the span of less than 3½ octaves.

[[Bryan Deister]] has demonstrated a [[7L 2s]] mapping for [[77edo]] in [https://www.youtube.com/shorts/wSZez2KgP2U ''microtonal improvisation in 77edo''] (2025). [[Tsaharuk]] is a member of the [[Schismatic family]] that splits the (highly accurate) fifth (~[[3/2]], as 45\77) into five parts (9\77), which function as lesser tridecimal neutral seconds ~[[13/12]]. Two of them (18\77) make a flat minor third ~[[20/17]]; three of them (27\77) make a sharp major third ~[[14/11]]; and four of them make a near-just tridecimal augmented fourth ~[[18/13]], which serves as the dark generator for the 7L 2s scale in the manner of Mavila, but since it is not mapped as a fourth, it can be stacked to get an actual near-just fourth or fifth (depending upon direction of stacking), needing ten to do so, as in [[Mabila family|Mabila]]. The overall range is approximately three and a half octaves (which slope upwards mildly), but each octave is missing a few notes.

+=== 33edo (demonstrated to work) ===
+[[Bryan Deister]] has demonstrated two mappings for [[33edo]] that function for the temperaments [[Augmented]] ([[Augmented family#Triforce|Triforce]], 33d val, [[3L&nbsp;3s]] scale with 7:4 step ratio) and [[Bohpier]] (33cd val, [[8L&nbsp;1s]] scale with 4:1 step ratio). The down-right (forward chroma version) or rightward (reverse chroma version) generator is a somewhat flat Alpharabian tendoneutral second ~[[12/11]] which can be stacked to get several consonant intervals; however, some of them map inconsistently. Two of these generators make a near-just neogothic minor third ~[[13/11]], mapped consistently. Three of these generators make a near-just septimal major third ~[[9/7]] by sound, but the mapping only works if 9/7 is constituted as (3♭ × 3♯) ÷ 7 or as 9 ÷ 7♭ (33d val). Four of these generators make a near-just lesser septimal tritone ~[[7/5]], mapped consistently ([[patent val]] or 33cd val). Six of these generators make a flat classic major sixth ~[[5/3]] by sound, but the mapping only works if 5/3 is constituted as 5♭ ÷ 3 (33c val). Seven of these generators make a near-just classic minor seventh ~[[9/5]] by sound, but the mapping only works if 9/5 is constituted as (3♭ × 3♯) ÷ 5 or as 9 ÷ 5♭ (33c val). The range is a bit over six octaves in the forward chroma version or five octaves in the reverse chroma version; in both cases, the octaves slope moderately downwards resulting in a vertical wraparound.

Right + down-right divides the octave into slices of 14\56; as an interval in its own right, this is the same as the minor third of [[12edo]], which functions as ~[[19/16]] and ~[[25/21]] (both being near-just). Down-right alone is 5\56, which is the [[Normal forms#Minimal_form|minimal form]] generator for [[Bidia]]; it functions as the classic diatonic semitone ~[[16/15]], the large septendecimal semitone ~[[17/16]], and the small septendecimal semitone ~[[18/17]], meaning that the charisma [[256/255]] and the semitonisma [[289/288]] are both tempered out; two of them make a rather sharp whole tone ~[[9/8]]; three of them (passing the quarter-octave) make a mildly sharp classic minor third ~[[6/5]], although the afore-mentioned quarter-octave (12edo-style) minor third is easier to reach; in contrast, the near-just classic major third ~[[5/4]] is very easy to reach with just two moves rightwards, and a down-right move from this reaches the moderately flat fourth ~[[4/3]]; two more down-right moves reaches the rather sharp fifth ~[[3/2]]. The efficiency is almost as good as that of the diatonic mapping, with no missed notes and one repeated note per octave; the overall range is somewhat under five octaves, with no notes chopped off by the left and right edges before reaching the end of overall range. The cost of this is that octaves slant downwards.

+[[Bryan Deister]] has used a [[Biyatismic clan#Zeus|Biyatismic (Zeus)]] layout with a [[7L&nbsp;1s]] scale (9:5 step ratio) for [[68edo]], as demonstrated in [https://www.youtube.com/shorts/CO1AslAu9E0 ''microtonal improvisation in 68edo''] (2025). The rightward generator 9\68 is a combination of the Alpharabian tendoneutral second ~[[12/11]] and the undecimal submajor second ~[[11/10]], and two of these make a near-just classic minor third ~[[6/5]], with the biyatisma ([[121/120]]) being tempered out. The chroma of the scale (4\68, upwards on this layout) is the near-just diptolemaic chromatic semitone ~[[25/24]], and is convenient to use as a second generator (even though such is not required to avoid [[contorsion]]) to access other consonant intervals quickly, although sometimes with strange preferences built in &mdash; for instance, the septimal whole tone ~[[8/7]] is much easier to reach (at 13\68) than the Pythagorean whole tone ~[[9/8]] (which requires a substantial vertical reach at 12\68), while the septimal minor third ~[[7/6]] (at 15\18) is a much longer vertical reach than the classic minor third ~6/5 (at 18\68), and the septimal major third ~[[9/7]] is a much longer vertical reach (at 25\68) than the classic major third ~[[5/4]] (at 22\68). Fortunately the fourth (~[[4/3]], at 28\68), the Axirabian paramajor fourth (~[[11/8]], at 31\68), the Axirabian paraminor fifth (~[[16/11]], at 37\68) and fifth (~[[3/2]], at 40\68) are all easy to reach as long as they do not go through a vertical wraparound (as happens to the fourth in the bass octave). The range is four octaves plus two notes, and octaves slope upwards &mdash; not severely, but a vertical wraparound is unavoidable if note 0 is placed to get complete octaves as defined to reach from note 0 to note 0.

In the version of Skwares used for this, instead of substantially sharpening the undecimal major third ~[[14/11]] (or even a septimal major third ~[[9/7]]) to get a diatonic fourth ~[[4/3]] (by stacking and octave-reducing four generators), the undecimal major third (7\20) is near-just, and the fourth is very flat at 480{{c}} (corresponding to the Blackwood sharp fifth at 720{{c}}). Octaves are nearly level (sloping down very gradually), and the range is a bit over 11 octaves, which suggests dividing the keyboard into zones for different instruments.

+== Cantonismic Lumatone mappings ==

+[[Bryan Deister]] has demonstrated a [[Cantonismic]] (flipped and rotated diatonic) mapping of [[64edo]] in [https://www.youtube.com/shorts/ag1FbgAuR6I ''microtonal improvisation in 64edo''] (2025). In this mapping, the rightward generator 7\64 is mapped as a slightly sharp tridecimal supraminor second ~[[14/13]], and the [[cantonisma]] (10985/10976) is tempered out, so that three of them make a fairly sharp classic major third ~[[5/4]], and eight of them make a near-just undecimal neutral seventh ~[[11/6]]; note that apart from ~5/4, these ratios depending upon partial cancellation of errors in the harmonics as represented by 64edo. The rightward generator is actually the short step of the easiest scale to play on this layout (provided that the scale is positioned not to go through a vertical wraparound), with the down-right step being 10\64, which corresponds to the [[Patent val|patent]] (not [[direct approximation]]) whole tone ~[[9/8]], thus enabling a rotated diatonic scale. Octaves alternate between far and near superimposed on an overall slant away over the range of three whole octaves (having no missing notes) plus a fourth octave that has some notes chopped off by the right edge, and some fragmented note sequences in the upper left and lower right corners. A side effect of the alternation of octaves is that accessing the fourth and fifth can be easy or hard depending upon not only the root note, but also the octave &mdash; for instance, in the middle and mid-right octaves, 27\64 and 37\64 are both easily reached from 0\64, but in the second full octaves, they same interval requires a long finger stretch if the root note is greater than 0, and the rotated diatonic scale goes through a vertical wraparound (and moving note 0 would simply cause other root notes to have the same problem in some of the octaves).

The rightward generator 5\58 functions as the classic diatonic semitone ~[[16/15]], the large septendecimal semitone ~[[17/16]], and the small septendecimal semitone ~[[18/17]], meaning that the charisma [[256/255]] and the semitonisma [[289/288]] are both tempered out. The rightward generator is also the [[normal forms|minimal form]] of the [[Diaschismic]] generator, and indeed the [[diaschisma]] 2048/2045 is also tempered out. This generator makes a slew of intervals of reasonable prime limit that are not far from just: two of them make a near-just whole tone ~[[9/8]]; three of them make a mildly flat classic minor third ~[[6/5]]; four of them make a mildly flat undecimal major third ~[[14/11]]; five of them make a near-just classic acute fourth ~[[27/20]]; six of them pass the [[semioctave]] to make a slightly flat greater septimal tritone ~[[10/7]]; seven of them make a slightly flat septimal superfifth ~[[32/21]]; eight of them make a slightly flat tridecimal supraminor sixth ~[[21/13]]; nine of them make a near-just septimal major sixth ~[[12/7]]; and ten of them make an extremely accurate undecimal supraminor seventh ~[[20/11]]. Other common intervals such as the moderately sharp (although high in relative error) classic major third ~[[5/4]], the near-just perfect fourth ~[[4/3]], and the near-just perfect fifth ~[[3/2]] are in very easy reach of the chain of rightward generators, and not very distant from the root note. This may be sufficient compensation for the reverse chroma and the range of only three full octaves (which slope only slightly upward), with large partial octaves being chopped off by the upper left and lower right corners.
-=== 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 [https://www.youtube.com/shorts/8xqjUkuZFaI ''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.

This yields a range of over five octaves, although the note 0 positions alternate between middle and near/far. (In the demonstration video, active keys on the Lumatone are cut back at both the left and right edges to yield exactly five octaves.) With this mapping, notes of the [[11L&nbsp;2s]] scale line up in pairs of row segments (of 6\37 offset from each other by the large MOSstep 3\37, and cut by the small MOSstep 2\37), which may make this mapping attractive for users wishing to play [[Ivan Wyschnegradsky]]'s Diatonicized Chromatic scale in a tuning system different from [[24edo]], while still retaining respectable (though not full piano) range.

A logical implication of splitting the ~7/4 into five meantone whole tones is that the near-just classic major third ~[[5/4]] is very easily accessible as two of these divided generators, and the only slightly flat lesser septimal tritone ~[[7/5]] is easily accessible as three of them. As convenient as this rightward generator is, it would produce a contorted mapping if not for a second generator; the upwards generator 7\62 is convenient for this as a a tridecimal neutral second that functions as both ~[[12/13]] and ~[[13/14]] (the buzurgisma/dhanvantarisma [[169/168]] is tempered out); backing off from ~7/4 by two of these generators gives the fifth (the flat ~[[3/2]] shared with [[31edo]]), while backing off from ~7/5 by two of these generators gives a moderately flat classic minor third ~[[6/5]]. Octaves slant down moderately, and the range is just under 4⅓ octaves with no missed notes and no repeated notes.

+== Magic (Divination/Soothsaying) related Lumatone mappings ==
+=== 82edo (demonstrated to work) ===
+[[Bryan Deister]] has demonstrated a [[8L&nbsp;6s]] mapping of [[82edo]]. Being even 82edo supports a [[semioctave]] period, with the diagassormisma ([[3042/3025]]) being tempered out in the [[patent val]] or the kalisma ([[9801/9800]]) being tempered out in the 82e val; this enables it to use the (somewhat sharp) septimal major third ~[[9/7]] (as 30\82) as a generator (which would be [[contorted]] down to [[41edo]] with a whole octave period), in a temperament like [[Magic family#Soothsaying|Soothsaying]] or [[Magic family#Divination|Divination]], but using the septimal major third as a generator instead of the classic major third ~[[5/4]].  (Since 82edo also supports actual Soothsaying in its patent val and actual Divination in its 82e val, it is also possible to use generator 26\82, the somewhat flat ~[[5/4]], although the resulting [[6L&nbsp;4s]] scale is a bit more tricky to play using this layout.) The range is about 2¾ octaves with no missed notes, and the octaves slant down.

+== Meantone Lumatone mappings ==
+=== m-Chromatic Lumatone mappings ===
+==== 81edo (demonstrated to work) ====
+[[Bryan Deister]] has demonstrated the m-chromatic ([[7L&nbsp;5s]] with 8:5 step ratio) mapping for [[81edo]] in [https://www.youtube.com/shorts/5O6Cyawjkd8 ''''microtonal improvisation in 81edo''] (2025). The rightward generator 8\81 functions as ~[[15/14]] and ~[[16/15]]; six of them make the alternate sharp fifth. The down-right generator 5\81 functions as ~[[23/22]] and ~[[24/23]]; two of them make an Alpharabian tendoneutral second (~[[12/11]]); four of them make the near-just octave-reduced 19th harmonic ~[[19/16]]; eleven of them make a near-just classic minor sixth ~[[8/5]]. The patent fifth 47\81 is four rightward generators plus three down-right generators. All that said, the patent fifth itself works perfectly well as a generator of the 7L&nbsp;5s scale, as well as for the entire layout, as befits (rank-2) [[Meantone]], so that the use of dual generators is a matter of convience rather than a requirement. The range is just over three octaves, with no missed notes, and the octaves slant down moderately.

+== Reversed-Chroma Compressed Tetracot Lumatone mappings ==
+=== 75edo (demonstrated to work) ===
+[[Bryan Deister]] has demonstrated a compressed [[1L&nbsp;5s mapping of [[75edo]] in [https://www.youtube.com/watch?v=5-G2KkYfKLs&list=WL&index=343&pp=gAQBiAQB8AUB ''microtonal improvisation in 75edo''] (2025-06-22). This combines the temperament of [[Tetracot]] with the idea of the compressed [[Lumatone mapping for Porcupine]], by reversing the chroma. (This also contains the Tetracot [[6L&nbsp;1s]] scale, but playing that scale in this layout requires backtracking.) This expands the overall range to more than five octaves, but too much so for anything so large as 75edo, thereby causing missed notes (although it demonstrates how such a mapping could shine for a smaller EDO or a hypothetical XL-sized Lumatone that has room for all of the notes).

+== Superlimmal Lumatone mappings ==
+=== 80edo (proposed and untested) ===
+Proposed and untested [[5L&nbsp;7s]] [[Canousmic_temperaments#Superlimmal|Superlimmal]] mapping for [[80edo]]. This layout using the generator 9\80 (which functions as ~[[13/12]], ~[[14/13]], and ~[[27/25]]) has very efficient use of keys (with no missed notes and just one repeated note per octave), but octaves slope down severely and wrap around even within the span of less than 3½ octaves.

+== Tsaharuk (Schismatic) Lumatone mappings ==
+=== 77edo (demonstrated to work) ===
+[[Bryan Deister]] has demonstrated a [[7L&nbsp;2s]] mapping for [[77edo]] in [https://www.youtube.com/shorts/wSZez2KgP2U ''microtonal improvisation in 77edo''] (2025). [[Tsaharuk]] is a member of the [[Schismatic family]] that splits the (highly accurate) fifth (~[[3/2]], as 45\77) into five parts (9\77), which function as lesser tridecimal neutral seconds ~[[13/12]]. Two of them (18\77) make a flat minor third ~[[20/17]]; three of them (27\77) make a sharp major third ~[[14/11]]; and four of them make a near-just tridecimal augmented fourth ~[[18/13]], which serves as the dark generator for the 7L&nbsp;2s scale in the manner of Mavila, but since it is not mapped as a fourth, it can be stacked to get an actual near-just fourth or fifth (depending upon direction of stacking), needing ten to do so, as in [[Mabila family|Mabila]]. The overall range is approximately three and a half octaves (which slope upwards mildly), but each octave is missing a few notes.
