Heya Paul,

Don't know if you're reading tuning or tuning-math, but wondered
if you wouldn't mind posting an explanation of how you finally
chose the cutoffs for the temperament lists in your new paper.

Oh, and are your new lists available online anywhere?

I'm reading both.

Oh yeah, I found an "instant" message from you on that, but you
weren't there for me to reply to it.

See /tuning-math/message/9317 for a
previous "moat"-based cutoff that was discussed for 7-limit.
Something similar was done for the 5-limit which included all the
main-sequence 5-limit temperaments in my paper except Passion.

Then Dave Keenan, on and off the tuning-math list, became more and
more convinced that a concave cutoff makes little sense, and that a
convex (probably elliptical) cutoff would generally be more
appropriate. Slightly swayed by his comments, I went for straight-
line cutoffs (a compromise that has the advantage of being very
simple), that included all the temperaments the "moats" did and only
very few more.

I mentioned this here:
/tuning-math/message/10378

I then ended up also including two 5-limit "exotemperaments" and two
5-limit "bonus temperaments", so the total went from 50 to 54.

No, but again, I'm happy to snail-mail the paper to anyone who wants
it.

And hopefully Igliashon is restoring for you the preliminary keyboard
layouts that were being discussed here.

It'd be great to have the 7-limit list in the tuning list's
database area (with the 5-limit one). I'd offer to enter it
myself, but I still haven't found my paper copy.
