[[Bryan Deister]] has used ~~a layout~~ for [[30edo]] that ~~was~~ inspired by the layout for [[29edo]] (rather than being made for any specific temperament)~~, as~~ demonstrated in [https://www.youtube.com/watch?v=NP3HGr3ZD70&lc=UgxFBmbxZa5dF4ZPj0F4AaABAg.AFzcn1LkVZNAG4JYIvXZvZ ''minuet in 30edo''] (2025). The right-moving generator is a somewhat flat Pythagorean whole tone (~[[9/8]], 5\30; and in the video, the row segments that include note 0 are colored solid red). The up-moving generator is a somewhat flat tridecimal supraminor second (~[[14/13]], 3\30); neither would be able access the full gamut on its own, but together they cover the full gamut with a generous allotment of repeated notes (indicating that if this layout was to represent a particular temperament, that would have to be a rank-3 temperament if having an octave period, or a rank-2 temperament dividing the octave into multiple periods). The range is a bit under five octaves, with octaves slanting up (while wrapping around) at the same angle as the right-moving generator.

[[Bryan Deister]] has used layouts for [[30edo]] that were inspired by the diatonic layout for [[29edo]] (rather than being made for any specific temperament). The original version is demonstrated in [https://www.youtube.com/watch?v=NP3HGr3ZD70&lc=UgxFBmbxZa5dF4ZPj0F4AaABAg.AFzcn1LkVZNAG4JYIvXZvZ ''minuet in 30edo''] (2025).

The range is a bit under five octaves, with octaves slanting up (while wrapping around) at the same angle as the right-moving generator.

A version of this in which the upwards and down-right generators of the above mapping are interchanged is demonstrated in [https://www.youtube.com/watch?v=2TxCWDYUvYc ''30edo improv''] (2025). Octaves alternate between far/near and middle, superimposed on an overall mild downwards slant; the range is somewhat more than that of the original version, at slightly over five octaves.
