Roland KF-90 用户手册

With the KF-90, just by pressing the One Touch Program [Arranger] button, 
you can select Automatic Accompaniment. Automatic Accompaniment is a 
feature that immediately plays an optimal accompaniment based on the 
accompaniment pattern of the Music Style and the chords you finger on the 
keyboard. Using Automatic Accompaniment, you can play with an 
impressive accompaniment, even when you perform alone. Also, by 
varying the Music Style, accompaniment pattern, and chords, you can easily 
enjoy a wide range of arrangements of the same song.

A Music Style is an accompaniment style that has been designed to fit in 
with a particular musical style.

There are many different varieties of music around the world, and each one 
has its own unique features. What gives jazz its “jazziness” and classical 
music its unmistakable classical feel is the unique combination of elements, 
such as the instruments used, melody, and phrasing, which interact to create 
the musical character of the genre. A Music Style makes use of such 
elements to bring out the distinctive atmosphere and mood of each musical 
genre.

A Music Style is made up of a set of six performance states called 
“Divisions.”

Also, a Music Style is made up of five performance parts: “Rhythm,” “Bass,” 
“Accompaniment 1,” “Accompaniment 2,” and “Accompaniment 3.”
