→72edo (demonstrated to work but awaiting approval): Added temperaments; this layout needs to be moved to a page for temperaments with names, but the page for that currently has the maximum number of Lumatone mappings before triggering the "Template include too large" error, so a comprehensive reorganization is needed first |
→72edo (demonstrated to work but awaiting approval): Add step number for down-right generator, and then insert Bryan Deister's Lumatone mapping for 94edo after this (temperament Kleischismic, Garibaldi, and Cassandra, but this mapping is temporarily stuck here pending a comprehensive reorganization) |

=== 94edo (demonstrated to work but awaiting approval) === | |||
[[Bryan Deister]] has demonstrated the [[11L 2s]] mapping of [[94edo]] in [https://www.youtube.com/shorts/Zx4xbJhXmgc ''microtonal improvisation in 94edo''] (2025). In the application of this temperament to this mapping, the rightward step corresponds to a stack of two quite accurate ~[[16/11] generators (51\94, and the [[octave complement]] is ~[[11/8]], at 43\94) after octave-reduction. This makes it a mapping for 11-limit (or higher) [[Schismatic_family#Kleischismic|Kleischismic]], a temperament (or a close relative of one) used extensively by [[Ivan Wyschnegradsky]] in his [[24edo]] compositions. Similarly, if one uses the highly accurate ~[[4/3]] (39\94, octave complement ~[[3/2]] as 55\94) and stacks two of these, the result is a rightward double step, making this mapping also work for [[Garibaldi]] and [[Schismatic_family#Cassandra|Cassandra]] (although with some vertical wraparound challenges as noted following). The range is a bit under three octaves, and the octaves slope up, so note 0 is set to a point on the left edge ¾ of the way down (to get note 0 two octaves higher to be ¾ of the way up); this results in a skipped note 1 in the lowest note 0 to note 0 octave, but if one is willing to assign one key to a non-isomorphic position, the note 92 in the lower left corner (from the octave below the lowest note 0) could be reassigned to the missing note 1. A diatonic scale, or better yet a Ptolemy's intense diatonic (Zarlino) scale appears possible to do using both hands, although the octave slope causes the wraparound point to change with octave. | |||
