That's a good criterion, but (even with a max scale size) was it
sufficient to close this list?

Yeah, Kleismic[11] came up long ago, and I rejected it in favor of
Kleismic[8].  ;)

I have nothing to say, but I wish I did.  Does anybody
else have anything to say?  If so, you may say it now.

Other than, if I understand this, it's what I've been pining
for all along -- defining temperaments with maps.  Unforch,
I haven't tracked the reasoning behind what why maps found
with this technique should be canonical.  Would anybody
besides Gene consider them natural mappings for their fav.
temperament(s)?

Any progress on this?

I can't say I see how applying a temperament to any 12-et piece would
be "straightforward"?  Do you do this in maple?

The scale files? Then see readme.txt. I could save the archive
in Unix format, but then there'll be Windows editors to
become fussy.

You could use Audio Compositor as Carl did with his temperament
exercise. AC has been fixed recently. Convert the seq file to
a midi file first, then use example/midi/mts.
Or use a tunable softsynth with a MIDI loopback, only that will affect
the timing a bit.
In 133-tET there are two fifths you can use.

I'm mapping 12 pitches to 12 other pitches.  I was under the impression
this conversion required mapping intervals to intervals.

Why?

Yahoo's case-sensitive -- "Gene".  Must run on unix...

Gene, you might try converting your Scala files from Windows to
Unix linebreaks before opening them, using a text editor such as
EditPad Lite.

I think the canonical version sounds more just in some sense,
though it seems slightly melodically warped.

So this is done with a simple 12-to-12 mapping?  Can you upload
the scala file you used?

That's a .seq file, no?
