Due to the dreaded "template include too large" error, moved the Valentine Lumatone mappings here from the main [[User:Lucius_Chiaraviglio/Keyboard_Layout_Lab|Keyboard Layout Lab]] page.

== Valentine Lumatone mappings ==

[[User:TheUniverseOfMusic|The Universe of Music]] invented the [[Valentine]] [[15L&nbsp;1s]] (or [[1L&nbsp;14s]]) mapping for [[31edo]]; I thought that while this mapping suffers in range for 31edo, from the demonstration video, it clearly works. It occurred to me that this mapping might really shine for larger EDO sizes, so I made some, including a couple that use [[15L&nbsp;1s]] for construction but have it so soft that even though they are still technically on the Valentine temperament, they are far outside its optimal tuning specifications. And then [[Bryan Deister]] tried out the one for [[61edo]], and it works.

Note that the different inventors/testers of these mappings have different ideas about where to put note 0, so the position of note 0 is not always consistent between EDO sizes.

=== 31edo (demonstrated to work) ===

''(This was copied from [[Lumatone mapping for 31edo]], for comparison with the larger EDO [[Valentine]] mappings below.)''

[[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, each outlining a Valentine [[15L&nbsp;1s]] scale).  This layout is inspired by the Ultra-Compressed version of the [[Lumatone mapping for porcupine]], but is 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.

=== 46edo (proposed and untested) ===

Octaves start to slant down a bit.  Playability not tested.

=== 61edo (demonstrated to work) ===

[[Bryan Deister]] has used the following layout, as demonstrated in [https://www.youtube.com/shorts/1Ai__APev5M ''microtonal improvisation in 61edo''] (2025), inspired by the [[Valentine]] version of the [[Lumatone mapping for 31edo]], but with a different idea how to use Valentine, so that the color scheme in the demonstration video has runs of 14 (rather than 16) keys in a row of the same color, except for solid dark blue keys being in groups of 5 (this scheme being chosen to favor easy visibility of major and minor thirds rather over outlining the [[15L&nbsp;1s]] or [[1L&nbsp;14s]] scale). Unlike the 31edo mapping that inspred this one, octaves are in an alternating pattern of near/far and middle with a slight overall upward slant, but all notes are still represented at least once; the range is just slightly over two octaves (not counting some considerable gamut fragments in the upper left and lower right corners).
{{Lumatone EDO mapping|n=61|start=5|xstep=4|ystep=5}}

=== 76edo (proposed and untested) ===

Octaves slant down severely, but all notes still represented at least once.  Playability not tested.
{{Lumatone EDO mapping|n=76|start=0|xstep=5|ystep=6}}

=== 77edo (proposed and untested) ===

Inspired by the [[Valentine]] version of the [[Lumatone mapping for 31edo]], the [[15L&nbsp;1s]] (or [[1L&nbsp;14s]]) mapping for [[77edo]] succeeds in avoiding missed notes in the middle octaves; the range is a bit over two octaves, and the octaves slant up. This mapping is a placeholder proposed as a way to avoid the missed notes of the layouts above, although at the cost of some common intervals being spaced very widely, and with considerable gamut fragments present in the upper left and lower right corners.
{{Lumatone EDO mapping|n=77|start=0|xstep=5|ystep=6}}

=== 78edo (proposed and untested) ===

What happens if we go softer than Valentine should be?  Octaves now slant up only slightly, and all notes are still represented.  Playability not tested.
{{Lumatone EDO mapping|n=78|start=0|xstep=5|ystep=6}}

=== 79edo (proposed and untested ===

What happens if we go even still softer than Valentine should be?  Octaves now slant down slightly, and all notes are still represented.  Playability not tested.
{{Lumatone EDO mapping|n=79|start=0|xstep=5|ystep=6}}
