This layout is numbered as for [[92edo]], but note 91 is actually a duplicate of note 0. The range is just one note short of 3 full octaves, with octaves sloping down gently, unlike the fully isomorphic version, which avoids the interruption from the duplicated note 0 and has slightly greater range, but at the cost of greater (and opposite) octave slope and a vertical wraparound of note 0 with ascending octaves (as well as producing a discontinuity in scales). This mapping has the same generators as the fully isomorphic version, as described below. | ||

== | === 101edo (demonstrated to work) === | ||
[[Bryan Deister]] has demonstrated a pseudo-isomorphic pseudo-diatonic mapping for [[101edo]] in [https://www.youtube.com/shorts/qS4fpB_uIyo ''101edo improv''] (2025). This layout is numbered as for [[102edo]], but note 101 (which does not appear here due to missing notes) is actually a duplicate of note 0. Note that the colors in this video are scrambled; however, the sound is recognizably diatonic even though this is not a true diatonic layout for 101edo. | |||

== MOS and MODMOS Subset Lumatone Mappings == | |||
These work like the pseudo-isomorphic mappings above, but with the additional consideration of deliberately using non-coprime generators on all axes to take a MOS or MODMOS subset of their tuning systems. | |||
=== 31edo (2 mappings demonstrated to work) === | |||
==== Right-up 15L 1s MOS subset pseudo-antidiatonic ==== | |||
For playing strictly in the Valentine 15L 1s scale (with no accidentals), it is possible to map just the Valentine scale by multiplying the antidiatonic mapping for [[16edo]] by 2 and treating note 31 as a duplicate note 0 (which never actually appears). [[Bryan Deister]] has demonstrated this in [https://www.youtube.com/watch?v=Aiihs4vqyfI ''16 tone improv (31edo)''] (2025). This gives back the range of just under five completely level octaves, and would even allow for division into multiple manuals. | For playing strictly in the Valentine 15L 1s scale (with no accidentals), it is possible to map just the Valentine scale by multiplying the antidiatonic mapping for [[16edo]] by 2 and treating note 31 as a duplicate note 0 (which never actually appears).

=== | ==== Down-right 15L 1s MOS subset pseudo-slendric ==== | ||
Continuing with the concept of only accessing every other note of [[31edo]] (again with a hidden note 31 that duplicates note 0), rotating the [[Valentine]] [[15L 1s]] scale to run down-right (instead of right-up) makes for easy playing of diatonic-sounding phrases (although with a rightward generator of 6\31, this is actually more like [[Slendric]]), while in a fairly compact layout having a range of over five octaves which slope mildly upwards.

=== 94edo (demonstrated to work) === | |||
[[Bryan Deister]] has demonstrated a pseudo-isomorphic pseudo-diatonic mapping for [[94edo]] in [https://www.youtube.com/shorts/KJ5dbF4aH2A ''Twinleaf Town - Pokémon Diamond and Pearl (microtonal cover in 94edo)''] (2026) that takes a 19 note subset supporting an almost-diatonic scale with a 15:10 step ratio overall, but with one of the steps (which one depends upon choice of root note) always being shortened by 1\94. This layout is numbered as for [[95edo]] and laid out as for [[19edo]], with the potential for two complete manuals and one incomplete manual, with note 94 (which is one of the missing notes) actually being a duplicate of note 0. | |||
