User:BudjarnLambeth/311edo MOS scales

This user page is editable by any wiki editor.

As a general rule, most users expect their user space to be edited only by themselves, except for minor edits (e.g. maintenance), undoing obviously harmful edits such as vandalism or disruptive editing, and user talk pages.

However, by including this message box, the author of this user page has indicated that this page is open to contributions from other users (e.g. content-related edits).

This list was calculated by xenoindex for the Xenharmonic Alliance Discord server; I am posting it here so that readers can access the information, however it shouldn't be moved the main space until a wiki editor (possibly future me) rewrites it in a more wiki-friendly format --BudjarnLambeth (talk) 02:37, 11 October 2025 (UTC)
