Quoting Rustom Mody <rustompmody(a)gmail.com>om>:
I have a piano (I am not sure what to call a touch
sensitive 7-octave
Casio) that has 7 tunings: Equal, Just, Werckmeister-III and so on.
I try always to fit my music to the best possible temperament.
I am also a linux user -- recently started using the excellent nted
software to write up music.
So the question: How does one specify alternative temperaments to timidity?
Have a look at Scala:
http://www.huygens-fokker.org/scala/
Seems like it can output tuning files in a format that timidity can
use (try timidity -Z tuningfile )
