Determining the Version Number of Your ROM Objects (Intonation Tables 18–22)
As you’re scrolling through the list of intonation tables, you may notice a listing for an
eighteenth intonation table with a name such as 18 Obj vn.nn. This isn’t really another
intonation table. Rather, this is where the K2661 stores the version number of some of your ROM
objects. If you ever need to find out what version of ROM objects you’ve got loaded, this is
where you look. Simply go to the Master page, then scroll the Intonation parameter until 18 is
displayed. If you have more than one block of ROM objects installed, you’ll see additional
“tables,” up to and including 22. And don’t forget to return to your correct intonation table
when you’ve checked the version numbers of your ROM objects.
List and Description of Intonation Tables
In general, you should select a nonstandard intonation table when you’re playing simple
melodies (as opposed to chords) in a particular musical style. When you use intonation tables
based on pentatonic scales, you’ll normally play pentatonic scales to most accurately reproduce
those styles. An excellent reference source for further study of alternative tunings is Tuning In:
Microtonality in Electronic Music, by Scott R. Wilkinson.
1 Equal No detuning of any intervals. The standard for modern western
music.
2 Classic Just Tunings are defined based on the ratios of the frequencies
between intervals. The original tuning of Classical European
music.
3 Just Flat 7th Similar to classic Just, but with the Dominant 7th flatted an
additional 15 cents.
4 Harmonic The perfect 4th, Tritone, and Dominant 7th are heavily flatted.
5 Just Harmonic
6 Werkmeister Named for its inventor, Andreas Werkmeister. It’s fairly close to
equal temperament, and was developed to enable transposition
with less dissonance.
7 1/5th Comma
8 1/4th Comma
9 Indian Raga Based on the tunings for traditional Indian music.
10 Arabic Oriented toward the tunings of Mid-Eastern music.
11 BaliJava1 Based on the pentatonic scale of Balinese and Javanese music.
12 BaliJava2 A variation on 1Bali/Java, slightly more subtle overall.
13 BaliJava3 A more extreme variation.
14 Tibetan Based on the Chinese pentatonic scale.
15 CarlosAlpha Developed by Wendy Carlos, an innovator in microtonal
tunings, this intonation table flats each interval increasingly,
resulting in an octave with quarter-tone intervals.
16 Pyth/aug4 This is a Pythagorean tuning, based on the Greek pentatonic
scale. The tritone is 12 cents sharp.
17 Pyth/dim5 This is a Pythagorean tuning, based on the Greek pentatonic
scale. The tritone is 12 cents flat.
18–24 Obj vn.n Not an intonation table; indicates version number of K2661
ROM objects.
