Ammonite + Gariberttet + Porcupinefish Lumatone mappings: Turns out the demo video was of a different temperament mapping, but these are still good to keep around
Ammonite + Gariberttet + Porcupinefish Lumatone mappings: Got approval for the Forward Chroma version of the 37edo mapping; adjust description a bit

=== 37edo (proposed but untested) ===
=== 37edo (2 mappings) ===


Alternatives to the [[Porcupine]] mapping for [[37edo]] that stay in the same temperament clan are the [[Porcupine_family#Ammonite|ammonite]]/[[Porcupine_family#Porcupinefish|porcupinefish]] [[3L 2s]] (9:5 step ratio) mappings, which also function for [[Subgroup_temperaments#Gariberttet|gariberttet]] (as 37b). The generator for ammonite is 14\37, easily available as one key right plus one key down-right in both versions of this mapping; it functions as a near-just Barbados third (tridecimal semisixth, ~[[13/10]]). The generator for porcupinefish is 5\37, easily available as one key down-right (forward chroma) or one step right (reverse chroma); it functions as an undecimal neutral second (a slightly flat ~[[11/10]] and a sharp ~[[12/11]], tempering out the biyatisma [[121/120]]). The generator for gariberttet is 9\37, easily available as one key right (forward chroma) or one key down-right (reverse chroma); it functions as a near-just tridecimal minor third (~[[13/11]]).

The generator for gariberttet is 9\37, easily available as one key right (forward chroma) or one key down-right (reverse chroma); it functions as a near-just tridecimal minor third (~[[13/11]]).

The range is a bit under 7½ octaves, which slope down mildly, with no repeated notes and no missed notes.
The range is a bit under 7½ octaves, which slope down mildly, with no repeated notes and no missed notes.  [[Bryan Deister]] has used this mapping in [https://www.youtube.com/shorts/mVRbcB2hoBU ''37edo prelude''] (2026).

The total range is just short of eight octaves, but while the middle octaves have no missing notes and a few repeated notes to mitigate vertical wraparounds, the first and last octaves have many notes chopped off at the edges, and the octaves slope down enough to incur a vertical wraparound.

Currently, no demo video is available for this mapping.
