Lumatone mapping for 36edo: Difference between revisions

The [[5L 1s]] (7:1 step ratio, upside-down scale) large reverse chroma mapping uses a slightly larger but very hard scale to compact the standard diatonic scale into two strings of single-step movements (although still rotated from the custmoary orientation), while also making offset strings of [[6edo]] into compact down-right key sequences, thereby dividing each octave into six parts, which may be useful for playing divided-octave temperaments. However, this makes fingerings for many chords somewhat awkward while putting octaves all over the place.

A 5L 1s (7:1 step ratio, large forward chroma) version of the Slendric mapping uses a large chroma (thus making a very hard version of this scale), and achieves octaves that only slope up moderately (but more than in the 1L 4s mapping) while still having the notes of the standard diatonic scale still easily accessible, although still rotated from their customary orientation. Offset strings of 6edo are now compact upwards key sequences, which may still be useful for playing divided-octave temperaments, although more likely to pass through a vertical wrapround than in the reverse-chroma 5L 1s mapping. [[Bryan Deister]] has demonstrated this mapping in [https://www.youtube.com/watch?v=psvrsa10-Wo ''36edo jam''] (2025)].

Another good option is the [[4L 2s]] [[Baladic]] mapping, which divides the octave in two to add easily accessible ratios of 13 & 17 to slendrics 2.3.7 subgroup and keeps octaves near horizontal, while keeping the less well tuned ratios of 5 and 11 distant from one-another.
