Yes. That's Right.
Actually, there are two different problems: Some music makes use of
more than 12 pitches per octave, and then it is good to get LilyPOnd
write it directly.
That's actually what I was asking.
How can we make lilypond's midi file play in different tuning
systems, in different pitchs, and/or in a flexible way, (e.g. when
I would like all the major 3rds of every major chord in a piece --
so it's not a fixed certain notes, but rather, a condition for
certain notes -- to be played "just intonation" or otherwise tuned.)
(Before my final decision of how the pitches should be tuned or
played, so to be heard.)
This can be used in Timidity using the -Z option on a tuning file:
timidity -Z <tuning> <midi>
Such files can be created using Scala (see below).
Actually, I was trying to convince my ears first that,
"the major 3rds of every major chord in a tonic piece should be
played a little bit lower -- as 'just intonation' tuned, rather
than 12-equal temperamented," and hoping Lilypond's midi could play
that way.
Try 53-ET and 31-ET in say Scala (see below). In 53-ET, the
Pythagorean tuning the major scale is
9 9 4 9 9 9 4
and the Just major is
9 8 5 9 8 9 5
So it is easy to compare. 31-ET plays the interval 5/4 very exactly. See
http://en.wikipedia.org/wiki/31_equal_temperament
http://en.wikipedia.org/wiki/53_equal_temperament
So, it it possible?
If so, how?
For this, use say Scala <http://www.xs4all.nl/~huygensf/scala/>. You
can try out chords, scales modes, create tuning files for Timidity,
and retune MIDI files directly.
