Pseudo-Isomorphic Lumatone Mappings

Mappings that can be generated by the isomorphic mechanism by specifying a number of notes per equave that is different from the actual number of notes.

61edo (demonstrated to work but awaiting approval)

(This sub-section is a placeholder.) Despite the missing notes, Bryan Deister has demonstrated this mapping in 61edo prelude (2025).

70edo (demonstrated to work but awaiting approval)

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 half of ~81/80 (moderately inflated).

87edo (demonstrated to work but awaiting approval)

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).

91edo (demonstrated to work)

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.
