There are many conceivable ways to map [[73edo]] onto the onto the Lumatone keyboard. However, the [[Standard Lumatone mapping for Pythagorean]] is unable to cover the full gamut of every octave, with both the sharp ([[patent val]]) and flat (b val) versions having many skipped notes.

If not for the problem of failing to cove the complete gamut (such as on a hypothetical XL-size Lumatone having at least 365 keys within the span of five octaves), the sharp version would be a respectable mapping for [[Immunity]]; while the flat version would be a respectable [[Deeptone]] mapping.

[[Bryan Deister]] has demonstrated the [[8L 3s]] mapping of [[73edo]] in [https://www.youtube.com/shorts/meZYE1Yj2pY ''microtonal improvisation in 73edo''] (2025). The rightward generator is an acute minor second that functions as both ~[[14/13]] and ~[[27/25]] (the ratwoflsma ([[351/350]]) is tempered out), and two of them make a mildly flat ~[[7/6]] septimal minor third (the buzzurgisma/dhanvantarisma ([[169/168]]) and the ragisma ([[4375/4374]]) are tempered out), and three of them make a moderately sharp ~[[5/4]] major third (the [[cantonisma]] (10985/10976) and the [[sensipent comma]] (78732/78125) are tempered out). The range is slightly over three full octaves, which are nearly level and have no missing notes.
