There are many conceivable ways to map 27edo onto the onto the Lumatone keyboard. Only one, however, agrees with the Standard Lumatone mapping for Pythagorean.

Keep in mind that 27edo is a superpyth temperament, so 5/4 is mapped to the interval of an augmented second (e.g. a 5/4 above C is D♯). Therefore if 0 is 1/1 on this mapping, 9 represents 5/4 and you can find that by going over to 5 (e.g. C → D) and then going up to 9 (D → D♯). If you want root – 3rd – 5th triads to be accessible in a more intuitive way, the 7L 6s tetracot mapping may be preferable.

If you want to maximise your range, the myna one is the widest one that still covers the whole gamut, spanning 8 octaves in its most compressed MOS. Though, the 4L 3s MOS has a 6:1 step ratio, making it quite awkward.
