That's probably the one he posted on this list in SEP/OCT of '97, in 
which the Comma of Pythagoras was put entirely in the central 
temperament octave, leaving a circle of pure 4ths and 5ths inside. 
That seriously beating octave was used to lay out the remaining 
octaves (although it would seem that proceeding outwards by pure 5ths 
would do the same thing). Whatever the 5th relationships (3:3 or 6:4) 
or the octaves (similar) were specified, this tuning scheme was 
certainly a lesson in the tolerance of new musical experiences. <g>

But as Bernard points out, the semitone based on the 19th root of 3 
is a horse of a different feather. Thanks from reminding us of Jim's 
pure 5ths temperament. It's nice for historical purposes to have it 
on the list again.
