 Mappings that can be generated by the isomorphic mechanism by specifying a number of notes per interval of equivalence that is different from the actual number of notes (generally, 1 extra note which is actually a duplicate of the next note 0).
+=== 18edo (demonstrated to work but awaiting approval) ===
+A pseudo-isomorphic pseudo-diatonic mapping for [[19edo]] that duplicates note 0 (as note 18) enables diatonic playing while keeping octaves level &mdash; it is the [[19edo]] diatonic layout, but with only 18 unique notes per octave.  This is demonstrated in [[Bryan Deister]]'s [https://www.youtube.com/shorts/hNmse4IUWL0 ''18edo improv''] (2025).

+=== 52edo (demonstrated to work but awaiting approval) ===
+A version of the Pseudo-Pentacircle mapping for [[52edo]] that duplicates note 0 (as note 52, as if making a layout for [[53edo]]) keeps the octaves level.  This is demonstrated in [[Bryan Deister]]'s [https://www.youtube.com/shorts/PgSsSM5pJcM ''52edo improv''] (2025).
