			[[Bryan Deister]] has demonstrated a pseudo-isomorphic mapping for [[70edo]] in [https://www.youtube.com/watch?v=-NEq3jKHjzs ''Improv in 70edo''] (2025) that uses one duplicated note in each octave to achieve a pseudo-diatonic layout for ease of access to common consonant intervals, although it does not include all the notes of the tuning system.

			=== Pseudo-Antidiatonic ===
			[[Bryan Deister]] has demonstrated a pseudo-isomorphic mapping for [[70edo]] in [https://www.youtube.com/shorts/ZDU75YabROE ''70edo prelude''] (2025) that uses three duplicated notes in each octave to achieve a pseudo-antidiatonic layout. Notes 70, 71, and 72 are duplicates of 0, 1, and 2, respectively; of these, the ones appearing on the layout are 0 and 70, 1, and 72. Playing as on a true antidiatonic layout results in a 1L<sub>1</sub> 1L<sub>2</sub> 5s [[MODMOS]] having a step ratio of 21:14:9.

	However, due to its size, this mapping does not cover all the notes. In addition, the best approximation to [[5/4]] is a quadruply augmented or pentuply diminished 7th, which is impossible to play with the root note of the chord. In most cases it will make more sense to use the c val, where it is a diminished 4th.

			The [[6L 4s]] mapping is meant to get as many notes as possible onto the space available on existing Lumatones, rather than attempting to fit any particular temperament, although it is a type of mapping supported by Diaschismic. This mapping gets three full octaves and the better part of another octave, with no missed notes and a moderate slope (comparable to the mapping above, but in the opposite direction). [[Bryan Deister]] has demonstrated this mapping in [https://www.youtube.com/shorts/I42JQ98WPZI ''microtonal improvisation in 70edo''] (2025).
