	[[Bryan Deister]] has demonstrated a pseudo-isomorphic mapping for a [[49L 1]] MOS subset of [[99edo]] in [https://www.youtube.com/shorts/GNio1PMp9BA ''99edo improv''] (2026). Since the step size is quite small, and yet the step ratio is 2:1, this enables playing a highly diatonic sound even though the layout is not truly diatonic, instead approximating a warped version of [[50edo]]. As with the standard diatonic mapping that it approximates, the the range is just short of five octaves, with no notes missing from the 49L 1s MOS scale.

	A pseudo-isomorphic pseudo-diatonic mapping for [[18edo]] that duplicates note 0 (as note 18) enables diatonic playing while keeping octaves level — it is the [[19edo]] diatonic layout, but with only 18 unique notes per octave. Alternatively, it can be interpreted as the 4L 3s ~~Janko~~ layout, but with a duplicate of note 0 added, which allows it to support both the 4L 3s scale (3:2 step ratio) and a 5L 1s<sub>1</sub> 1s<sub>2</sub> MODMOS scale (3:2:1 step ratio). This is demonstrated in [[Bryan Deister]]'s [https://www.youtube.com/shorts/hNmse4IUWL0 ''18edo improv''] (2025).

			=== 63edo (demonstrated to work) ===
			[[Bryan Deister]] has used a pseudo-isomorphic pseudo-diatonic mapping laid out as for [[64edo]], but with note 63 actually being a duplicate of note 0 (but it is off the edge, so not visible unless this mapping would be used on a hypothetical XL-sized Lumatone). This is demonstrated in [https://www.youtube.com/shorts/EEAJ0AaWoJM ''63edo improv''] (2025-10-19), with a monochrome color scheme for additional challenge.

			=== 94edo (demonstrated to work) ===

			[[Bryan Deister]] has demonstrated a pseudo-isomorphic pseudo-diatonic mapping for [[94edo]] in [https://www.youtube.com/shorts/KJ5dbF4aH2A ''Twinleaf Town - Pokémon Diamond and Pearl (microtonal cover in 94edo)''] (2026) that takes a 19 note subset supporting an almost-diatonic scale with a 15:10 step ratio overall, but with one of the steps (which one depends upon choice of root note) always being shortened by 1\94. This layout is numbered as for [[95edo]] and laid out as for [[19edo]], with the potential for two complete manuals and one incomplete manual, with note 94 (which is one of the missing notes) actually being 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).
