Hello, i was trying to use the Arprestrictor

(http://www.u-he.com/scripting/Arprestrictor.php (http://www.u-he.com/scripting/Arprestrictor.php))

and i noticed that if i change for example the value of semitones of note C, and press the "make" button,then in the text file bellow, note 0 value changes from 0.0000 to 100.0000.

if start over and this time i change only the value of cents to 50
of the same note C, and press the "make" button again, in the text file bellow, note 0 value changes from 0.0000 to 100.0000.
And if instead i enter cents=100 then note 0=200.0000.

That means that Arprestrictor thinks that 1 semitone=50 cents?
However the google research i made says that 1 semitone=100 cents.

I have prepared a document in which i calculated and wrote down the differences in cents for some scales (byzantine scales, if anyone is curious or interested)
So ,should i devide all my cents calculations by 2 , before entering them to Arprestrictor?

(Also, the cents column, even though accepts values >99, it doesnt accept values <-99.I dont know if this is a bug, but because i couldn't enter -100 cents, i tried to enter -1 semitone instead, and then i looked at the text Arprestrictor made and i compared ,thats how i noticed all the above)

I did mentioned this to u-he about a year ago, that for changing 16 cents you need to dial in the value 8.
Doesn't seem to important to them and probably would break some patches if changed.

It's just that every new user would have to find out this by themselves so it would be practical to have this documented somewhere else than this forum.

Yes, it's a "misthink" on my side. I remembered from back in school that it was 50 cent per semitone, 100 cent per full tone. I may have remembered wrong.

Unfortunately, as Bathrobe said, we can't just change things without breaking presets. We might be able to do so one day, biut it'll require some serious coding for safety and vast testing effort.

You don't have to change it, however it would be cool if you could just have it briefly mentioned somewhere in the Arprestrictor page, for other people to see.. (funny mistake though ). Without the Arprestrictor one has to mess with the complex scala software,which i couldnt even intall, very thoughtfull you created that page...
Really thanks both for answering!

Whoops!


I wonder if it's possible to retain the value in the patch itself, but just change the text string that is displayed as parameter value to a correct one?

Yeah, maybe... will think about it (some time after the ongoing challenge tho...)

What exactly are you trying to achieve? Which scales?

Are they not already available?

hi there, i didn't expect more answers so didn't look back , until accidentally today, so sorry for answering late.
i did what i wanted thanks, i divided cents that i ve already calculated by two and it works great..

The scales i was talking about are used in orthodox christian religion music, and they are called in greek "diatoniki" "enarmonios" ,"chromatiki malaki" "chromaiki skliri". If i try to translate these names to english its "diatonic" ,"harmonic", "chromatic soft" ,"chromatic hard". And then based on what note of the above scales you start to play, there are some modes.But i don't know the theory well enough…
