However, neither it ([[patent val]]) nor the flat fifth (b val) are able to cover the full gamut of every octave, with both having some skipped notes. | |||

[[Bryan Deister]] has demonstrated a pseudo-isomorphic mapping for [[61edo]] in [https://www.youtube.com/shorts/S9bJnllI7CI ''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). | |||

The [[Tetracot]] mapping is also missing a few notes in each octave. | |||

[[Bryan Deister]] has used the following layout, as demonstrated in [https://www.youtube.com/shorts/1Ai__APev5M ''microtonal improvisation in 61edo''] (2025), inspired by the [[Valentine]] version of the [[Lumatone mapping for 31edo]], but with a different idea how to use Valentine, so that the color scheme in the demonstration video has runs of 14 (rather than 16) keys in a row of the same color, except for solid dark blue keys being in groups of 5 (this scheme being chosen to favor easy visibility of major and minor thirds rather over outlining the [[15L 1s]] or [[1L 14s]] scale). Unlike the 31edo mapping that inspred this one, octaves are in an alternating pattern of near/far and middle with a slight overall upward slant, but all notes are still represented at least once; the range is just slightly over two octaves (not counting some considerable gamut fragments in the upper left and lower right corners). | |||
