User:Lucius Chiaraviglio/Keyboard Layout Lab/Non-Isomorphic Lumatone mappings: Difference between revisions

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).

[[Bryan Deister]] has demonstrated a pseudo-isomorphic mapping for [[61edo]] in [https://www.youtube.com/shorts/S9bJnllI7CI ''61edo prelude''] (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 61 is actually another note 0, so as to reset octave pitch down by half of ~[[81/80]] (considerably deflated).

[[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).

[[Bryan Deister]] has demonstrated a pseudo-isomorphic mapping for [[87edo]] in [https://www.youtube.com/shorts/5OH9OOGeuX4 ''87edo waltz''] (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 87 is actually another note 0, so as to reset octave pitch down by half of ~[[81/80]] (moderately inflated).
