The Tune Equal Division window in CSE just got a whole lot better.
Previously, the window offered only a minimum of options:
That was fine for a quick mapping of an EDO, but what if you wanted more control? You had to do things like transpose and tweak the Global Key and Hz settings. Not ideal. What if you wanted a non-octave equal division? You had to use an Algorithm for that.
Not any more. Now you get all these options in one place, plus you can assign a specific degree of the scale to a specific key on the keyboard with a specific frequency in Hz, all at once. Could it get any simpler? Let's try it and see…
Example 1: 15EDO starting on C. Here's what it looks like in the new Equal Division window, using the options listed above that CSE has offered for years.
To make this more interesting, let's instead use the new to key with frequency option to map the first degree to middle C to 264 Hz.
This gives us the following result.
Example 2: Now for some new magic. Bohlen-Pierce 13th root of 3 scale. We just select non-octave, type in 3 for the period, and 13 for the number of divisions. We'll map the first degree to middle C at 264 Hz again.
Here is the result.
Pretty simple, huh? Also notice that after one period of the non-octave scale is completed, the tuning entry gets multiplied a factor of the period (in this case, 3). Multiples accrue for each iteration of the period, so the scale is correct and you can also still see the proper scale degree in the tuning entry, rather than just an inscrutable decimal number as is the case when using an EDIV algorithm.
Oh, and that non-octave period can be anything you want there. You can write a ratio or a decimal, or even a full blown tuning entry, with up to 32 operators. For cents, you would first make sure you have cents selected as your Unit, and then just type a + before the value, so a period of +1203.44 means 1203.44 cents (3.44 cents more than an octave). You could also type that in as (2/1)+3.44 if you preferred.
To check it out, just login and download the update from the CSE software page.
Enjoy!

NOTE: The new Equal Division window was introduced in version 2.9.70, and a few bugs were fixed in update 2.9.72, issued June 1.
