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.
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 but awaiting approval)
A pseudo-isomorphic pseudo-diatonic mapping for 19edo 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. This is demonstrated in Bryan Deister's 18edo improv (2025).
52edo (demonstrated to work but awaiting approval)
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).
Bryan Deister has demonstrated a pseudo-isomorphic mapping for 61edo in 61edo prelude (2025). This mapping retains a diatonic-style layout for ease of access to common consonant intervals, although it does not include all the notes of the tuning system. Each note 61 is actually another note 0, so as to reset octave pitch down by half of ~81/80 (considerably deflated).
Bryan Deister has demonstrated a pseudo-isomorphic mapping for 70edo in Improv in 70edo (2025). This mapping retains a diatonic-style 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).
Bryan Deister has demonstrated a pseudo-isomorphic mapping for 87edo in 87edo waltz (2025). This mapping retains a diatonic-style layout for ease of access to common consonant intervals, although it does not include all the notes of the tuning system. Each note 87 is actually another note 0, so as to reset octave pitch down by half of ~81/80 (moderately inflated).
Bryan Deister has demonstrated a pseudo-isomorphic mapping for 91edo in microtonal improvisation in 91edo (2025). 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 below, 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.
