→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 |

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]]). | 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 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.

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. | 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.
