[[Bryan Deister]] has used a layout for [[52edo]] in which the right generator is 9\57 ([[10/9]] ~ [[9/8]], as in [[Meantone]], but this would be contorted without an additional generator); and the upward generator is 8\57, which maps to a just slightly flat ~[[11/10]] (and not to ~[[12/11]] or ~[[10/9]] in the patent val, thus differing from [[Porcupine]] despite producing a rotated but otherwise similar [[1L 6s]] scale). Octaves are nearly level, just barely sloping downwards; the compass is somewhat under 4 octaves. This layout is demonstrated in [https://www.youtube.com/watch?v=4NZvSgS3ryY ''57edo improv''] (2025); in the video, some notes are cut off in the lower and middle left edge and the upper right corner due to the use of only 2 MIDI channels; on the plus side, this shows where to put note 0 on the left side to avoid losing notes in the bottom octave due to running off the edge of the keyboard. | [[Bryan Deister]] has used a layout for [[52edo]] in which the right generator is 9\57 ([[10/9]] ~ [[9/8]], as in [[Meantone]], but this would be contorted without an additional generator); and the upward generator is 8\57, which maps to a just slightly flat ~[[11/10]] (and not to ~[[12/11]] or ~[[10/9]] in the patent val, thus differing from [[Porcupine]] despite producing a rotated but otherwise similar [[1L 6s]] scale).

Note that down and right proceeds by 1\57, thus making for an easy glissando (also demonstrated in the video). | ||
