There are many conceivable ways to map [[95edo]] onto the onto the Lumatone keyboard. Although 95edo is a dual-fifth temperament, the [[Standard Lumatone mapping for Pythagorean]] only works for the sharp fifth (95 patent val), because the flat fifth (95b val) is shared with [[19edo]], thereby yielding five mutually-exclusive rings of fifths. Due to the large number of notes, the diatonic mapping and many others will fail to cover the entire gamut.

=== Quasi-Diatonic ===

A quasi-diatonic layout is also possible, which functions similarly to a diatonic mapping, but with the octaves shifting pitch class up by 2\95 with each higher octave. Thus, despite the missed notes, all notes are accessible in some octaves. [[Bryan Deister]] has demonstrated this in [https://www.youtube.com/shorts/aQapbuGFnhk ''Impostor Syndrome - Sidney Gish (microtonal cover in 95edo)''] (2025) with the MIDI mapping set to octave 1 | octave 2 | octave 2 | octave 3 | octave 3 | octave 4, to get the greater portion of the notes within each octave other than the bass (which is missing note 0 among other notes, whilethe last octave only has 3 notes represented), at the cost of less range.

== Tetracot ==

However, the best approximation to [[5/4]] in the diatonic mapping is a quadruply augmented 7th, while the second best is a quadruply diminished 7th, neither which are easy to play with the root note. The [[tetracot]] mapping works better for hitting harmonics, although the [[6L 1s]] mapping once again does not cover the whole gamut and the [[7L 6s]] one has octaves all over the place.

== Magus ==

The [[magus]] mapping is the optimal patent val for the temperament in the 11-limit and also fairly efficient, but very lopsided.
