As the page title implies, this page gets non-isomorphic Lumatone mappings, including those that can be generated by the isomorphic mechanism by specifying a number of notes per interval of equivalence that is different from the actual number of notes.
Named Note Lumatone Mappings
(This section is a placeholder.)
Pseudo-Isomorphic Lumatone Mappings
Mappings that can be generated by the isomorphic mechanism by specifying a number of notes per interval of equivalence that is different from the actual number of notes (generally, 1 extra note which is actually a duplicate of the next note 0).
18edo (demonstrated to work)
A pseudo-isomorphic pseudo-diatonic mapping for 18edo that duplicates note 0 (as note 18) enables diatonic playing while keeping octaves level — it is the 19edo diatonic layout, but with only 18 unique notes per octave. Alternatively, it can be interpreted as the 4L 3s Janko layout, but with a duplicate of note 0 added, which allows it to support both the 4L 3s scale (3:2 step ratio) and a 5L 1s1 1s2 MODMOS scale (3:2:1 step ratio). This is demonstrated in Bryan Deister's 18edo improv (2025).

A version of the Pseudo-Pentacircle mapping for 52edo that duplicates note 0 (as note 52, as if making a layout for 53edo) keeps the octaves level. This is demonstrated in Bryan Deister's 52edo improv (2025).

Pseudo-Diatonic
Bryan Deister has demonstrated a pseudo-isomorphic mapping for 70edo in Improv in 70edo (2025) that uses one duplicated note in each octave to achieve a pseudo-diatonic layout for ease of access to common consonant intervals, although it does not include all the notes of the tuning system. Each note 70 is actually another note 0, so as to reset octave pitch down by ~81/80 (moderately deflated).

92edo (demonstrated to work)
Bryan Deister has demonstrated a pseudo-isomorphic pseudo-diatonic mapping for 92edo in 92edo waltz (2025) that deliberately uses non-coprime generators on all axes to use a subset of 92edo to make 31 non-equal divisions of the octave in the form of a 30L 1s MOS scale with a 3:2 step ratio. This layout is numbered as for 93edo, but note 92 is actually a duplicate of note 0; due to missing notes, it does not actually appear here.

94edo (demonstrated to work)
Bryan Deister has demonstrated a pseudo-isomorphic pseudo-diatonic mapping for 94edo in 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.
