scala show data

Manuel,

With Scala 2.05f, I observe...

equal 6
show data

strictly proper
roth stability 0
lumma stability 1

show data

strictly proper
roth stability 423799.833333
lumma stability 1

show data

strictly proper
roth stability 67041792.766666
lumma stability 1

The goofy stability value seems to max out at the 67 value
despite further show data commands.

Manuel,

I also notice that "Lumma stability" is the title of the value
in the show data output, but "Lumma instability" is the title
in the help for show data.

Also in the help, the return type is given as n>1. But if it
really is stability you're returning, it would be 0 <= n <= 1,
right? Since it's the *portion* of the interval of equivalence
not covered by the spans of the interval classes...

-Carl

Thanks for the bug report Carl, it will be fixed in the
next version. Only ETs are affected.

Oops.

No, that's the condition for the value to be given, i.e. only
if the number of tones is greater than 1.

That bug is fixed now, along with some other ones.

There's a new feature which may be interesting,
in the Chromatic Clavier you can now arpeggiate or
hold a chord, and play with the mouse at the same
time. The chord is entered using the right mouse button,
like it could be done before.
Also new now is that when you open the chord list,
the selected chord is used (actually the nearest
approximation of it in the current scale), so you can
quickly change chords without having to click-enter them.
Please click on the Help button in the clavier window first
if there's some trouble.

With equal 6, I get .2 for Rothenberg stability.
How are you getting that? If I delete the 3rd
degree, it goes up to .4!

Grrmbl, this is rather shameful, don't know how
I got so sloppy. Anyhow, the bug krept in because
of an optimisation, using intermediate variables
for different calculations. I should test better.

Manuel

I've made an update to 1.84 of the command line version
in case anyone still uses it. Show data is also fixed
of course so Rothenberg stabilitity = 1 for ETs.

I used to test software for a living, and IMO you've
got more complexity in Scala than any one person
could test in their spare time, even if the data model
was perfect.

By the way, the installer puts a desktop shortcut
even if I tell it not to. ;)

Looks like the Windows version is fixed too (without a
version increment)... thanks, Manuel.

Even *I* don't use the console version anymore, though
it's one of the best command-line interfaces I've used.
I think it's cool that you are still maintaining it.

I'm really impressed with the speed of 2.05. Though it
is 9 megs of widgets, and one can't copy and paste to
the Windows clipboard as was possible with the console
version. . .

. . .Okay, I've installed both. :)

Oh, I'll look after that.

Thanks, there actually is one blind user (not on the
lists) who can't use the GUI-version.

Not completely true because, weird enough, you can do it
once. Right click in the main window, select "Enable text
editing", then select some text, press ctrl-C and that
can be pasted then. Any subsequent copy doesn't work unless
you restart the program.
