Roland AT20s Manuale Utente

 

This refers to changes that have been made in an original 

tune, by adding a new accompaniment or by changing the 

instruments used.

 

Automatic Accompaniment is automatic accompaniment 

when just a few keys in the lower section of the keyboard are 

pressed to specify the chord. 

 

This refers to the most commonly used types of chord, which 

are generally the following six types: major chords, minor 

chords, minor seventh chords, minor seventh ( 5) chords, 

dominant seventh chords, and diminished seventh chords.

 

Notes of two or more pitches sounded simultaneously. 

Chords consisting of three notes are called “triads,” and are 

the most basic type of chord.

 

This is the last part of the accompaniment. When you stop 

playing the Automatic Accompaniment, the AT-20S plays an 

Ending appropriate for the Rhythm. 

 

An effect that temporarily lowers the pitch and then 

gradually returns it to normal.

 

This is the introductory portion of an Automatic Accompa-

niment performance. The AT-20S plays an intro ideally 

suited to each Rhythm when it starts playing the Automatic 

Accompaniment.

 

When the lowest note of a chord is the root, the chord is said 

to be in “root position.” In contrast, forms of a chord in 

which other notes are the lowest pitch are called “inver-

sions.”

 

To silence a sound. The AT-20S provides a Track Mute 

function that allows you to turn off the track button indicator 

of a track on which music data has been recorded, so that the 

corresponding track will temporarily be silenced.

 

Settings such as sound selections, tempo, Rotary fast/slow.

 

A unit of data that contains the performance state of the 

instrument, such as sound selections and panel settings.

 

An effect that simulates the reverberation of a room or 

concert hall.

 

The root note is the basis of a chord. All chords are built on a 

root note, which is the part of the chord name given in 

uppercase letters.

 

An effect which simulates the modulation given to the sound 

when a rotating speaker is used. The Rotary effect produces 

two types of modulation: fast or slow.

 

An effect that adds a decay to each note. The AT-20S allows 

sustain to be applied to the voices of the upper part, lower 

part, and pedal part.

 

The AT-20S is able to produce the sounds of various instru-

ments. These sounds are called “Voices.”
