== Miracle + Ripple (both off-beat) Lumatone mappings == | |||
=== 83edo (demonstrated to work) === | |||
[[Bryan Deister]] has used the [[10L 1s]] layout for [[83edo]], as demonstrated in [https://www.youtube.com/shorts/vYhK-A74Kpg ''microtonal improvisation in 83edo''] (2025). The octaves slant downwards (with a wraparound in the first full octave) while moving to higher pitches, and the contiguous range (with all notes represented at least once, not counting non-contiguous notes in the upper left and lower right corners) is slightly over three octaves (although due to the Lumatone only being set up for a single MIDI channel in this video, the video only demonstrates approximately one and a half octaves). The generator is the semi-flat version of [[27/25]], as in [[ripple]] temperament, although it is necessary to constitute it as (3♭×3♯×3♭)/25 (using both the flat and sharp fifths in alternation) in order to map it correctly. Alternatively, since 83edo is at the intersection of ripple and [[miracle]] temperaments, the generator can be constituted as a flat [[secor]] ([[16/15]] ~ [[15/14]]), using the 83b val — not in the optimal tuning spectrum of miracle, but only needing to use the flat fifth. | |||

== Passion Lumatone mappings == | |||
=== 61edo (demonstrated to work, but awaiting verification) === | |||
[[Bryan Deister]] has used the [[12L 1s]] layout for [[61edo]], as demonstrated in [https://www.youtube.com/shorts/1Ai__APev5M ''microtonal improvisation in 61edo''] (2025). The generator is a nominal but very flat ~[[16/15]] (5\61, actually closer to [[18/17]], but only if constituted as (3♯×3♭)/17); this supports a very hard [[10L 1s]] scale, although the color scheme used in the video does not reflect this. The range is a bit under 4 octaves (and the octaves slant up) with provision of repeated notes, or actually a bit over 4 octaves if one is willing to accept some awkward positions in the left and right extremes of the layout. | |||

[[User:TheUniverseOfMusic|The Universe of Music]] has used the following layout, demonstrated in [https://www.youtube.com/watch?v=lK1JQWefj-s ''Her Gentle Touch''] (2025). In this video, even notes are mapped to red keys, and odd notes are mapped to purple keys). This layout uses the [[valentine]] as its scale of construction, inspired by the Ultra-Compressed version of the [[Lumatone mapping for porcupine]], but even more compressed. Octaves are in horizontal rows, but stretched out over a large distance (which would be even longer if the layout were not made extremely compressed), so that the range is just slightly over 3 octaves (not counting some gamut fragments in the upper left and lower right corners), while notes are repeated multiple times vertically (at a slant), which allows an easy reach for octaves and other intervals that would require very long fingers if only available purely horizontally. | [[User:TheUniverseOfMusic|The Universe of Music]] has used the following layout, demonstrated in [https://www.youtube.com/watch?v=lK1JQWefj-s ''Her Gentle Touch''] (2025).

The up-moving generator is an almost-just tridecimal supraminor second (~[[14/13]], 3\28). The range is a bit over five octaves, with octaves alternating near/far and middle with an overall small upwards slant. Although this layout was not designed for any particular temperament, it so happens that the right-moving generator matches [[Machine]]. | ||

== | === 30edo (demonstrated to work) === | ||
[[Bryan Deister]] has used a layout for [[30edo]] that was also inspired by the layout for [[29edo]] (rather than being made for any specific temperament), as demonstrated in [https://www.youtube.com/watch?v=NP3HGr3ZD70&lc=UgxFBmbxZa5dF4ZPj0F4AaABAg.AFzcn1LkVZNAG4JYIvXZvZ ''minuet in 30edo''] (2025). The right-moving generator is a somewhat flat Pythagorean whole tone (~[[9/8]], 5\30; and in the video, the row segments that include note 0 are colored solid red). The up-moving generator is a somewhat flat tridecimal supraminor second (~[[14/13]], 3\30); neither would be able access the full gamut on its own, but together they cover the full gamut with a generous allotment of repeated notes (indicating that if this layout was to represent a particular temperament, that would have to be a rank-3 temperament if having an octave period, or a rank-2 temperament dividing the octave into multiple periods). The range is a bit under five octaves, with octaves slanting up (while wrapping around) at the same angle as the right-moving generator. | |||
