=== Full gamut ===

{{u|TheUniverseOfMusic||The Universe of Music}} has used the [[Valentine]] mapping, demonstrated in [http://youtu.be/lK1JQWefj-s ''Her Gentle Touch''] (2025). (In this video, even notes are mapped to red keys, and odd notes are mapped to purple keys, each outlining a Valentine [[15L 1s]] scale.) This layout is inspired by the ultra-compressed version of the [[Lumatone mapping for porcupine]], but is even more compressed. Octaves are in horizontal rows, but stretched out over a large distance (which would be even longer if the layout were not made extremely compressed), so that the range is just slightly over 3 octaves (not counting some gamut fragments in the upper left and lower right corners), while notes are repeated multiple times vertically (at a slant), which allows an easy reach for octaves and other intervals that would require very long fingers if only available purely horizontally.

=== 15L 1s MOS subset pseudo-antidiatonic ===

For playing strictly in the Valentine 15L 1s scale (with no accidentals), it is possible to map just the Valentine scale by multiplying the antidiatonic mapping for [[16edo]] by 2 and treating note 31 as a duplicate note 0 (which never actually appears). [[Bryan Deister]] has demonstrated this in [https://www.youtube.com/watch?v=Aiihs4vqyfI ''16 tone improv (31edo)''] (2025). This gives back the range of just under five completely level octaves, and would even allow for division into multiple manuals.
