This is Graham Breed, you might check out some of his posts here on the LilyPond lists. > The Pitch Model > > Pitches in Lilypond are a combination of the position on the staff, > and the alteration relative to the nominal at that position, as a > rational fraction of a 200 cent whole tone.

You might try the regular.ly file which allows for ETs in the MIDI output. I can send you some examples for some of them, like E53. Graham has made a file that allows for more complicated microtonality, by using a high ET so that the microtones do not clash.
