Re: Just Intonation MIDI file

2011-09-14 Thread Nick Bailey
Well, the way we did it was to retune the synthesiser fluidsynth using the 
tunings (?) command. It was a slightly different problem because we wanted 19-
ET rather than messing about with pythagorean adjustments, which might have to 
change every time you modulate anyway? We found that not many commercial 
synths obey the midi tuning protocol (in fact none of the ones we looked at).

Off topic, I'd be interested in why you want to teach singers to sing out of 
tune anyway :D (that was a troll :) )

Here's a video about the 19ET stuff...

Just click on the first thumbnail. Sorry about the flash. HTML5 hasn't reached 
a 
browser near me yet :)

 How does one do this?
 
 I can find just intonation in the glossary but not in the rest of
 the documentation.
 
 I am interested in generating sound files for singing practice using
 the simple Pythagorean ratios.
 
 
 How can this be done?

Well, disappointingly they didn't do the tuning in Lilypond.
But they could have.

 the rest of the documentation.

Use regular.ly with tuning=#53 or some other equal
temperament that gets close enough for you.  Normally
notated notes will then be Pythagorean.
