I know of at least one person who's very fond of a 12-tone JI scale she came up with, which she happily plays in every key. She tattooed it onto her arm. I've played in 58-edo, which to me is basically indistinguishable from JI. It's just a little too big to use comfortably on the Lumatone. I can use it on the monome comfortably, but the monome doesn't have velocity sensitivity, which for me is a deal killer. On the Lumatone the biggest I feel comfortable playing is 46-edo. Fortunately, 46-edo sounds incredible. It doesn't have the best approximation to 5/4 -- it's 5 cents sharp -- but that error goes in the same direction as the error in 12-edo that we're used to, so (because we're all used to 12-edo) it sounds world better than, say, the 5/4 that 41-edo gives you, which is 6 cents flat.
