A scale is simply an ordered series of pitches. Each scale type sounds slightly different because the pattern of pitch differences between each note varies from one scale type to another.
LSSP includes a range of modules that represent the most common types of scale, but more fundamentally it defines a standard way of representing scales so that a scale can be carried down a cable from one module to another. These “scale signals” use S-Poly connections.
The structure of these scale signals is not particularly complicated (the first S-Poly channel specifies the number of notes in the scale and subsequent channels specify the pitches) so you can construct your own scales using the MONO TO S-POLY module.
Because chord signals in LSSP use exactly the same format as scales they are generally interchangeable.
The most flexible and yet in some ways most primitive common scale is the chromatic scale, it represents all the white and black notes that you would find on one octave of a piano keyboard.
If you look at the image above and twist your head 90 degrees to the left you will see that the module looks like the pattern of keys on a keyboard.
The major scale is the most used scale type in western music. Its pitches follow the same pattern as the white notes on a piano keyboard.
After major, the minor scales are perhaps the next most popular, but they are a bit of a mishmash. The theory makes sense but it’s not as straightforward as one would hope.
Minor scales tend to sound more sophisticated than Major scales.
The blues scale is very popular in blues, jazz, rock and other genres.
There are seven modal scales. Each has a slightly different pattern of intervals. The Ionian modal scale is identical to the major scale and the Aeolian modal scale is identical to the natural minor scale.
Purists will notice that the note names (in yellow) although correct in the sense that they identify the correct pitch aren’t quite right in that they always give the sharp version of an enharmonic pair. So, for instance, you might see something labelled as D# when strictly speaking is ought to be called an Eb. But as D# is the same pitch as Eb its not a massive concern. It’s a just something worth being aware of. A future update may deal with this issue.
