IMPORTANT NOTES  
556  
Handling Floppy Disks  
• When connecting / disconnecting all cables, grasp the  
651  
connector itself—never pull on the cable. This way you  
will avoid causing shorts or damage to the cable’s internal  
elements.  
• Floppy disks contain a plastic disk with a thin coating of  
magnetic storage medium. Microscopic precision is  
required to enable storage of large amounts of data on  
such a small surface area. To preserve their integrity,  
please observe the following when handling Floppy disks:  
• Never touch the magnetic medium inside the disk.  
• Do not use or store Floppy disks in dirty or dusty  
areas.  
• Do not subject Floppy disks to temperature extremes  
(e.g., direct sunlight in an enclosed vehicle). Recom-  
mended temperature range: 10 to 50° C (50 to 122° F).  
• Do not expose Floppy disks to strong magnetic fields,  
557  
• A small amount of heat will radiate from the unit during  
normal operation.  
\558a  
• To avoid disturbing your neighbors, try to keep the unit’s  
volume at reasonable levels. You may prefer to use  
headphones, so you do not need to be concerned about  
those around you (especially when it is late at night).  
\559b  
• When you need to transport the unit, pack it in shock-  
absorbent material. Transporting the unit without doing  
so can cause it to become scratched or damaged, and  
could lead to malfunction.  
such as those generated by loudspeakers.  
652  
• Floppy disks have a “write protect” tab which can protect  
560  
the disk from accidental erasure. It is recommended that  
the tab be kept in the PROTECT position, and moved to  
the WRITE position only when you wish to write new  
data onto the disk.  
• Do not apply undue force to the music stand while it is in  
use.  
\562  
• Use a cable from Roland to make the connection. If using  
some other make of connection cable, please note the  
following precautions.  
Rear side of the disk  
• Some connection cables contain resistors. Do not use  
cables that incorporate resistors for connecting to this  
unit. The use of such cables can cause the sound level  
to be extremely low, or impossible to hear. For infor-  
mation on cable specifications, contact the manufac-  
turer of the cable.

• Disks containing performance data for this unit should  
always be locked (have their write protect tab slid to the  
“Protect” position) before you insert them into the drive  
on some other unit (except the PR-300, or a product in the  
HP-G, MT, KR, or Atelier families), or into a computer’s  
drive. Otherwise (if the write protect tab remains in the  
“Write” position), when you perform any disk operations  
using the other device’s disk drive (such as checking the  
contents of the disk, or loading data), you risk rendering  
the disk unreadable by this unit’s disk drive.

• To insert a disk, push it gently but firmly into the drive—  
it will click into place. To remove a disk, press the EJECT  
button firmly. Do not use excessive force to remove a disk  
which is lodged in the drive.  
605a  
• Never eject a disk while reading or writing is in progress,  
since that can damage the magnetic surface of the disk,  
rendering it unusable. (The disk drive’s indicator will

Main Features  
We want to take a moment to thank you for your purchase of the Roland AT-20S “Atelier  
Series” Organ.  
The AT-20S is an electronic organ which provides a generous collection of rich organ  
sounds. In addition, it is designed to be easy to learn and use. In order to enjoy reliable  
performance of your new keyboard for many years to come, please take the time to read  
through this manual in its entirety.  
Basic concepts of the ATELIER series  
A full complement of organ sounds  
A wide range of basic organ sounds, ranging from jazz organ and pipe organ to theatre  
organ, are onboard so you are sure to enjoy having access to all the sounds you expect  
from an organ.  
Panel layout based on a tradition of emphasis on realtime operation  
Based on the idea that you should be able to sit down and begin playing immediately,  
the operation buttons of the panel are arranged by function as dictated by classic organ  
traditions, ensuring easy and intuitive operation. All models of the ATELIER series fea-  
ture the same operability, allowing you to start playing immediately even if you switch  
models.  
High-quality sounds that you can use without editing  
In addition to a full range of organ sounds, high-quality sounds such as strings and brass  
are also included onboard. You can simply select sounds and enjoy playing the organ-  
no need to perform complicated editing operations.  
Expansive lower keyboard with damper pedal for piano-like  
expressiveness  
Piano is indispensable to the performance of contemporary music. On the ATELIER se-  
ries, the lower keyboard features an expanded range that gives you the expressive pow-  
er of a piano. The keyboard also features half-damper pedal capability and initial touch  
sensitivity, both indispensable for piano performance.  
All models provide high-quality grand piano sounds.  
Design utilizes your existing music data  
The ATELIER series is designed so that even on new models, you will feel right at home  
and can begin playing immediately. Data compatibility has also been carefully taken  
into account, and song data or registration data from earlier models can be used without  
change.  
Music styles from around the world  
Many of the best-loved musical styles from around the world (rhythm and automatic ac-  
companiment patterns) are built in, allowing you to enjoy an international range of per-  
formances.  
Utilizes SMF music files  
Since a floppy disk drive is built in, you can use the wide array of commercially available  
SMF music files to enjoy ensemble performances or automatic playback.

Main Features  
Main Features  
Featuring the newly developed V-Arranger with sophisticated  
rhythm sounds and realistic automatic accompaniment  
You will enjoy rhythm and automatic accompaniment so realistic that it sounds like your  
own backup band is right there!  
Newly developed Active Expression sounds  
For some of the sounds, moving the expression pedal will vary not only the volume but  
also the tone, or add other sounds. From pianissimo to fortissimo, the tonal character of  
the sound itself will change as you perform a crescendo, or strings may appear behind  
the piano, creating dynamic changes in tonality.  
Human voices  
In addition to its diverse organ voices, the ATELIER-S series instruments also offer  
unique vocals, such as “Jazz Scat.”  
Harmony Intelligence  
The Harmony Intelligence function automatically adds harmony to the upper keyboard  
sound according to the chord you play in the lower keyboard. This gives you greater ton-  
al depth and a more powerful performance.  
Store disk styles in internal memory  
Although the Rhythm [Disk] button already contains various rhythms, these can be re-  
placed by rhythms from a music style disk. Rhythms that are loaded from a music style  
disk into internal memory will not be lost even when the power is turned off, so you will  
find it convenient to load frequently used rhythms into internal memory.  
The Lyrics for SMF Music Files can be displayed  
When playing back commercially available SMF music files with lyrics, the lyrics can be  
viewed on the instrument’s display, allowing you to enjoy karaoke.

• When connecting a microphone to the AT-20S, be sure to  
lower the volume. If the volume control is too high when  
the microphone is plugged in, noise may be produced by  
the speakers.  
• To prevent possible auditory damage, loss of hearing, or  
damage to the headphones, the headphones should not be  
used at an excessively high volume.  
Use the headphones at a moderate volume level.  
• Howling could be produced depending on the location of  
microphones relative to speakers. This can be remedied  
by:  
• Changing the orientation of the microphone.  
• Relocating microphone at a greater distance from  
speakers.  
• Lowering volume levels.

Selecting and Playing Sounds  
Selecting Voices  
The AT-20S is able to produce the sounds of various instruments. These sounds are  
called “Voices” (or tones). It is very easy to select voices.  
About the Voices and Parts  
The AT-20S has two keyboards and one Pedalboard, as shown below.  
From top to bottom these are called the “Upper Keyboard,” “Lower Keyboard,” and  
“Pedalboard.”  
fig.02-04  
Upper Keyboard  
Lower Keyboard  
Pedalboard  
The Upper Keyboard and Lower Keyboard each have two parts: “Organ,” “Orchestral.”  
You can select one voice for each part, meaning that it is possible to layer up to two voic-  
es on each keyboard and play them simultaneously.  
The voice of the “Solo” part can be layered on the Upper keyboard.  
The Pedalboard has the part: “Pedal.”

Using the Registration Buttons  
The AT-20S allows you to store sound settings and panel settings such as 4 in the Regis-  
tration buttons. There are a total of 4 Registration buttons, and one set of panel settings  
can be stored in each, allowing you to register a total of 4 different panel settings. Each  
set of panel settings that has been stored in a Registration button is called a “Registra-  
tion.”  
This provides a convenient way to change large numbers of panel settings during a per-  
formance, or to recall a complex panel setting.

Formatting Disks  
Before any floppy disk (new or used) can be used with the AT-20S, it must first be for-  
matted (prepared).  
Floppy disks must first be “formatted” (initialized) before they can be used by the AT-  
20S to store data. “Formatting” is the process of erasing any data which may have been  
on the disk and making the format of the floppy disk match the format of the device. The  
AT-20S cannot use a floppy disk that has a format differing from its own format.  
Formatting a disk will erase any data that may have been stored on it. Carefully check any  
previously used disk to be sure it doesn’t contain any valuable data.

This instrument contains two sound generators: one for SMF  
data playback and one for keyboard performance.  
When you use the MIDI connectors or the computer  
connector of the AT-20S to transmit musical data to external  
devices, for each keyboard (Upper, Lower, and Pedal) you  
can specify the channel on which your playing will be trans-  
mitted as MIDI messages.  
Normally, data received at the MIDI In connector will control  
only the sound generator for SMF data playback. However  
by changing the MIDI IN Mode setting, you can also control  
the keyboard sound generator from MIDI In.

About MIDI Connectors  
The AT-20S has two kinds of MIDI connectors.  
3. Use a MIDI cable (sold separately) to connect  
the MIDI connector on the external instrument  
to the MIDI connector on the AT-20S.  
Connecting these to the MIDI connectors on a MIDI  
instrument makes it possible for the two instruments to  
control each other.  
4. Turn on the external MIDI device and AT-20S.  
For instance, you can output sound from the other  
instrument or switch tones on the other instrument.  
You should also set the MIDI send channel as needed.

Meanings:  
When you do not want to erase it, press the [Reset] button  
then save the data on disk.

Glossary  
Arrangement  
Panel Settings  
This refers to changes that have been made in an original  
tune, by adding a new accompaniment or by changing the  
instruments used.  
Settings such as sound selections, tempo, Rotary fast/slow.  
Registration  
A unit of data that contains the performance state of the  
instrument, such as sound selections and panel settings.  
Automatic Accompaniment  
Automatic Accompaniment is automatic accompaniment  
when just a few keys in the lower section of the keyboard are  
pressed to specify the chord.  
Reverb  
An effect that simulates the reverberation of a room or  
concert hall.  
Basic Chord  
Root Note  
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,  
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.  
dominant seventh chords, and diminished seventh chords.  
Rotary  
Chord  
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.  
Notes of two or more pitches sounded simultaneously.  
Chords consisting of three notes are called “triads,” and are  
the most basic type of chord.  
Sustain  
Ending  
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.  
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.  
Voice  
Glide  
The AT-20S is able to produce the sounds of various instru-  
ments. These sounds are called “Voices.”  
An effect that temporarily lowers the pitch and then  
gradually returns it to normal.  
Intro  
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.  
Inversion  
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.”  
Mute  
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.

Generator  
either of these logos.  
The ATELIER series come equipped with GM2/GS sound  
generators.  
SMF with Lyrics  
“SMF with Lyrics” refers to SMF (Standard MIDI File) that  
contains the lyrics. When music files carrying the “SMF with  
Lyrics” logo are played back on a compatible device (one  
bearing the same logo), the lyrics appears in its display.  
General MIDI  
The General MIDI is a set of recommendations which seeks  
to provide a way to go beyond the limitations of proprietary  
designs, and standardize the MIDI capabilities of sound  
generating devices. Sound generating devices and music files  
that meets the General MIDI standard bears the General  
MIDI logo. Music files bearing the General MIDI logo can be  
played back using any General MIDI sound generating unit  
to produce essentially the same musical performance.  
General MIDI 2  
The General MIDI 2 is a set of recommended specifications  
that provide detailed definitions for functionality such as  
sound editing and effects that had not been defined in the  
General MIDI, and extend the sound map to allow a higher  
degree of performance expression and compatibility. Since  
the General MIDI 2 is compatible with the General MIDI, it is  
capable of reliably playing back music files bearing the  
General MIDI logo.  
GS format  
The GS Format is Roland’s set of specifications for standard-  
izing the performance of sound generating devices. In  
addition to including support for everything defined by the  
General MIDI, the highly compatible GS Format additionally  
offers an expanded number of sounds, provides for the  
editing of sounds, and spells out many details for a wide  
range of extra features, including effects such as reverb and  
chorus.  
Designed with the future in mind, the GS Format can readily  
include new sounds and support new hardware features  
when they arrive.  
Since it is upwardly compatible with the General MIDI,  
Roland’s GS Format is capable of reliably playing back GM  
Scores equally as well as it performs GS music files (music  
files that have been created with the GS Format in mind).  
This product supports both the General MIDI and the GS

Profile  
Hal Vincent  
Hal consistently delights his audiences with his keyboard artistry. He is equally at home  
on either the organ, piano, or electronic keyboard. Around the world, his concerts gen-  
erate the often heard comment “....we loved it because he plays our kind of music.” This  
is another of Hal’s special skills: a knack for knowing just what music to play on any oc-  
casion.  
An extensive repertoire combined with more than 30 years of world touring have netted  
Hal rave reviews while affording him the opportunity to work with some of the top  
names in show business. Hal has recorded several albums and published books of organ  
arrangements while establishing himself as an excellent clinician and teacher.  
Hector Olivera  
Hector Olivera was born in Argentina. He received his education at the Conservatory  
and the University of Buenos Aires followed by a scholarship at the famous Juilliard  
School of Music in New York. Olivera has performed extensively throughout the world  
including concerts at prestigious places such as the Notre Dame Cathedral in Paris and  
Carnegie Hall in New York. Hector Olivera’s expertise involves both the traditional pipe  
organ and the electronic organ. Presently Olivera tours internationally playing some of  
the world’s most magnificent pipe organs as well as his preferred electronic organ, the  
Roland Atelier for which he continues to collaborate with its development.

Jonas Nordwall  
A native of Portland, Mr. Nordwall received his Bachelor of Music Degree in 1970 from  
the University of Portland studying with Arthur Hitchcock. Additional study was done  
with Frederick Geoghegan, the noted English/Canadian organist. As a teenager, Jonas  
had the privilege to study with Richard Ellsasser, one of the greatest virtuoso organist of  
20th century.  
Besides serving as Director of Music for the First United Methodist Church in Portland,  
Oregon and as the Organist for the Oregon Symphony Orchestra.  
He has been a featured recitalist for national conventions of the American Theatre Organ  
Society and was Organist of the year for 1987.  
Ric Iannone  
Ric Iannone began playing the piano and accordion at the age of two and a half. By the  
time he was seven, he was performing public and private engagements with his musi-  
cian father. For more than 20 years Ric has performed and traveled extensively through-  
out the United States and Europe, delighting audiences with his unique playing style  
and music arrangements. He is equally comfortable playing the organ, piano or key-  
board, as a concert artist and product demonstrator.  
Rosemary Bailey  
Rosemary Bailey began playing the piano at the age of five, performing strictly classical  
music. She soon diversified and incorporated jazz and traditional popular styles in her  
repertoire. By the time she was nine years old, Rosemary had begun touring throughout  
the United states.  
Concurrently, she maintained a weekly radio show, The Rosemary Bailey Show, broad-  
cast from Chicago.  
Rosemary has performed with many name artists including Victor Borge and Peter Nero  
as well as the Duke Ellington Orchestra. She was also featured soloist with the Chicago  
Symphony under the direction of Dr. Leon Stein.  
At home on electronic as well as pipe organs, her concert schedule has taken her to such  
countries as Japan, South Africa, Canada, Italy, Spain, England, Holland, Denmark, Por-  
tugal, Germany and Australia.  
Rosemary’s unique arrangements involve the marriage of her classical and popular mu-  
sic background. Perfect pitch enables her to effortlessly field requests from the audience  
and adds spontaneity to all her programs.  
Rosemary has developed a following of musical devotees wherever she performs and  
her numerous recordings are sought after by young and old alike.
