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 note on a piano keyboard.
After major, the minor scales are perhaps the next most popular, but they are a bit of a mishmash. Music theory isn’t exactly scientific in nature.
Minor scales tend to sound a little more sophisticated than Major scales.
The blues scale is very popular in blues, jazz, rock and other genres.
