=== 336edo (demonstrated to work but awaiting approval) ===

The entire gamut of [[336edo]] will not fit on a Lumatone. Nevertheless, a Lumatone can be used to play a subset of it. One of these subsets is 7ed(575{{c}}), of which each increment corresponds to 23 increments of 336edo. For practical purposes, this is a non-octave tuning, although technically it repeats at the octave at 23 octaves, which would require a hypothetical XXXXL-sized Lumatone to implement and some kind of Shepard tone pattern to be all audible within the range of human hearing. [[Bryan Deister]] has demonstrated a mapping of this in [https://www.youtube.com/shorts/kPqYmCzZ8uY ''7ed(575 cents) improv''] (2025). In this, 7ed(575{{c}}) is doubled to 14ed(1150{{c}}), and then a compressed (non-octave) 4L 1s (3:2 step ratio) scale laid out on it if proceeding right and down, or a compressed 4L 2s (3:1 step ratio) scale if proceeding right and up. The range is over 6¼ instances of 1150{{c}}, which slope gently upwards.
