[[Bryan Deister]] has used the [[10L 1s]] layout for [[71edo]], as demonstrated in [https://www.youtube.com/shorts/nMMSQdIV30I ''71edo improv''] (2025). At 7\71, the generator is [[16/15]] ~ [[15/14]] only if 71b (or 71c, but not 71bc) is used; otherwise, it is necessary to use the mediant ~[[31/29]]) for proper mapping, making the temperament a strange mutation of [[Miracle]] that intersects with [[Ripple]] at 71b, not far from where Ripple intersects with the real Miracle temperament at [[83edo]] (as 83b). Octaves are very close to being horizontal; that said, if one purposely slopes up from bottom to top to make use of vertically repeated notes while going left to right while transversing two octaves, it is possible to play a [[20L 1s (4/1-equivalent)]] scale even as a rapid glissando, as demonstrated in the video (both ascending and descending). | [[Bryan Deister]] has used the [[10L 1s]] layout for [[71edo]], as demonstrated in [https://www.youtube.com/shorts/nMMSQdIV30I ''71edo improv''] (2025).

[[Bryan Deister]] has used the [[Porwell temperaments#Nessafof|Nessafof (Porwell)]] layout for [[54edo]], as demonstrated in [https://www.youtube.com/shorts/Bi5-YQUQHek ''microtonal improvisation in 54edo''] (2025). At 7\54, the generator is a near-just septimal neutral second (~[[35/32]]), of which 2 make a slightly flat minor third ~[[6/5]] (constituted in 54b), and 11 make a sharp ~[[8/3]] (which corresponds to the 54b flat fifth). The [[7L 1s]] scale (with a step ratio of 7:5) is expanded similar to the expanded [[Lumatone mapping for porcupine]], but with large and small step sizes reversed (meaning that [[8L 1s]] is not supported — the small step size would be negative). On the one hand, this makes octaves recede rapidly; but on the other hand, this also means that down and right gives a convenient ascending whole tone scale shared with [[12edo]], although this requires constituting the ~[[9/8]] whole steps as (3♭ × 3♯) / 8. The range is four full octaves. | |||
