== Pseudo-Isomorphic ==

[[Bryan Deister]] has demonstrated a pseudo-isomorphic mapping for [[70edo]] in [https://www.youtube.com/watch?v=-NEq3jKHjzs ''Improv in 70edo''] (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 70 is actually another note 0, so as to reset octave pitch down by ~[[81/80]] (moderately deflated).

=== Pseudo-Diatonic ===

[[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. Each note 70 is actually another note 0, so as to reset octave pitch down by ~[[81/80]] (moderately deflated).

=== 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.
