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 equave that is different from the actual number of notes.

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)

(This sub-section is a placeholder.) Despite the missing notes, Bryan Deister has demonstrated this mapping in Improv in 70edo (2025).

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.
