Important Notes

291b

In addition to the items listed under “IMPORTANT SAFETY INSTRUCTIONS” and “USING THE UNIT SAFELY” on pages 2
and 3, please read and observe the following:

Power Supply

301

• Do not connect this unit to same electrical outlet that is

being used by an electrical appliance that is controlled by
an inverter (such as a refrigerator, washing machine,
microwave oven, or air conditioner), or that contains a
motor. Depending on the way in which the electrical
appliance is used, power supply noise may cause this unit
to malfunction or may produce audible noise. If it is not
practical to use a separate electrical outlet, connect a
power supply noise filter between this unit and the
electrical outlet.

307

• Before connecting this unit to other devices, turn off the

power to all units. This will help prevent malfunctions
and/or damage to speakers or other devices.

308

• Although the LCD and LEDs are switched off when the

POWER switch is switched off, this does not mean that the
unit has been completely disconnected from the source of
power. If you need to turn off the power completely, first
turn off the POWER switch, then unplug the power cord
from the power outlet. For this reason, the outlet into
which you choose to connect the power cord’s plug
should be one that is within easy reach.

Placement

351

• Using the unit near power amplifiers (or other equipment

containing large power transformers) may induce hum.
To alleviate the problem, change the orientation of this
unit; or move it farther away from the source of inter­ference.

352a

• This device may interfere with radio and television

reception. Do not use this device in the vicinity of such
receivers.

352b

• Noise may be produced if wireless communications

devices, such as cell phones, are operated in the vicinity of
this unit. Such noise could occur when receiving or initi­ating a call, or while conversing. Should you experience
such problems, you should relocate such wireless devices
so they are at a greater distance from this unit, or switch
them off.

353

• Observe the following when using the unit’s floppy disk

drive. For further details, refer to “Before Using Floppy
Disks” (p. 6).

• Do not place the unit near devices that produce a

strong magnetic field (e.g., loudspeakers).

• Install the unit on a solid, level surface.

• Do not move the unit or subject it to vibration while

the drive is operating.

354b

• Do not expose the unit to direct sunlight, place it near

devices that radiate heat, leave it inside an enclosed
vehicle, or otherwise subject it to temperature extremes.
Also, do not allow lighting devices that normally are used
while their light source is very close to the unit (such as a
piano light), or powerful spotlights to shine upon the
same area of the unit for extended periods of time.
Excessive heat can deform or discolor the unit.

355b

• When moved from one location to another where the
temperature and/or humidity is very different, water
droplets (condensation) may form inside the unit. Damage
or malfunction may result if you attempt to use the unit in
this condition. Therefore, before using the unit, you must
allow it to stand for several hours, until the condensation
has completely evaporated.

356

• Do not allow rubber, vinyl, or similar materials to remain
on the unit for long periods of time. Such objects can
discolor or otherwise harmfully affect the finish.

358

• Do not allow objects to remain on top of the keyboard or
pedal board. This can be the cause of malfunction, such as
keys ceasing to produce sound.

359

• Do not paste stickers, decals, or the like to this instrument.
Peeling such matter off the instrument may damage the
exterior finish.

Maintenance

401b

• To clean the unit, use a dry, soft cloth; or one that is
slightly dampened. Try to wipe the entire surface using an
equal amount of strength, moving the cloth along with the
grain of the wood. Rubbing too hard in the same area can
damage the finish.

402

• Never use benzine, thinners, alcohol or solvents of any
kind, to avoid the possibility of discoloration and/or
deformation.

Repairs and Data

452

• Please be aware that all data contained in the unit’s
memory may be lost when the unit is sent for repairs.
Important data should always be backed up on a floppy
disk, or written down on paper (when possible). During
repairs, due care is taken to avoid the loss of data.
However, in certain cases (such as when circuitry related
to memory itself is out of order), we regret that it may not
be possible to restore the data, and Roland assumes no
liability concerning such loss of data.

Additional Precautions

551

• Please be aware that the contents of memory can be
irretrievably lost as a result of a malfunction, or the
improper operation of the unit. To protect yourself against
the risk of loosing important data, we recommend that
you periodically save a backup copy of important data
you have stored in the unit’s memory on a floppy disk.

552

• Unfortunately, it may be impossible to restore the contents
of data that was stored on a floppy disk once it has been
lost. Roland Corporation assumes no liability concerning
such loss of data.

553

• Use a reasonable amount of care when using the unit’s
buttons, sliders, or other controls; and when using its jacks
and connectors. Rough handling can lead to malfunctions.

554

• Never strike or apply strong pressure to the display.

555

•A small amount of noise may be heard from the display
during normal operation.

5

Important Notes

556

• When connecting / disconnecting all cables, grasp the
connector itself—never pull on the cable. This way you
will avoid causing shorts, or damage to the cable’s
internal elements.

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 shock­absorbent material. Transporting the unit without doing
so can cause it to become scratched or damaged, and
could lead to malfunction.

560

• 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.

• 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 infor­mation on cable specifications, contact the manufac­turer of the cable.

Before Using Floppy Disks

Handling the Floppy Disk Drive

602

• Install the unit on a solid, level surface in an area free from
vibration.

603

• Avoid using the unit immediately after it has been moved
to a location with a level of humidity that is greatly
different than its former location. Rapid changes in the
environment can cause condensation to form inside the
drive, which will adversely affect the operation of the
drive and/or damage floppy disks. When the unit has
been moved, allow it to become accustomed to the new
environment (allow a few hours) before operating it.

604

• 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
light up at full brightness when the drive is busy reading
or writing data. Ordinarily, the indicator will be less
brightly lit, or be extinguished.)

606

• Remove any disk from the drive before powering up or
down.

607

• To prevent damage to the disk drive’s heads, always try to
hold the floppy disk in a level position (not tilted in any
direction) while inserting it into the drive. Push it in
firmly, but gently. Never use excessive force.

608

• To avoid the risk of malfunction and/or damage, insert
only floppy disks into the disk drive. Never insert any
other type of disk. Avoid getting paper clips, coins, or any
other foreign objects inside the drive.

Handling Floppy Disks

651

• 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). Recom­mended temperature range: 10 to 50° C (50 to 122° F).

• Do not expose floppy disks to strong magnetic fields,
such as those generated by loudspeakers.

652

• Floppy disks have a “write protect” tab which can protect
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.

Rear side of the disk

Write
(can write new data onto disk)

Write Protect Tab

653

• The identification label should be firmly affixed to the
disk. Should the label come loose while the disk is in the
drive, it may be difficult to remove the disk.

654

• Store all disks in a safe place to avoid damaging them, and
to protect them from dust, dirt, and other hazards. By
using a dirty or dust-ridden disk, you risk damaging the
disk, as well as causing the disk drive to malfunction.

655

• 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.

Main Features

We want to take a moment to thank you for your purchase of the Roland AT-90S Luxury “Atelier Series” Organ. The AT­90S Luxury 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.

* The AT-90S Luxury is abbreviated in this manual as “AT-90SL” respectively.

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 feature 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 series, the lower keyboard features an
expanded range that gives you the expressive power 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 accompaniment patterns) are built
in, allowing you to enjoy an international range of performances.

Utilizes SMF music files

Compatible with GM2, the world standard in SMF music files, and equipped with its own floppy disk drive, the ATELIER
brings you access to the wealth of SMF music files available on the market. You can also mute parts, allowing you to
practice the part for each hand separately, and enjoy performing ensemble with the music files.

Main Features

Features

RSS reverb technology is used to create a high-quality ambience that surrounds the listener

The AT-90SL provides an AUX OUT for RSS Ambience, allowing you to enjoy very high quality RSS reverb sound. In
addition, a speaker is built into the panel, ensuring that the performer will also enjoy the exceptional sound quality.

Highly realistic rhythms and automatic accompaniment functions

All rhythms use data from performances by professional drummers, featuring high-quality patterns with all the grooves
and subtle nuance of the real thing. In addition, you can use automatic accompaniments that are perfectly matched to each
rhythm to enjoy the feeling of playing with your own band in the background.

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.

“Music Assistant” and “Quick Registration” functions

The “Music Assistant” function makes it easy to recall appropriate rhythm and sound settings simply by selecting a
desired atmosphere for your song. The “Quick Registration” function lets you use keywords to select wonderful
registrations created by top-ranking organists such as Hector Olivera.

Human voices and phrases

In addition to a full array of organ sounds, the ATELIER-S series provides human voices such as “Jazz Scat,” and human
voice phrases such as “Amen.”

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 tonal depth and a more powerful performance.

Rhythm Customize function lets you arrange the internal rhythms

You can use the “Rhythm Customize” function to edit the internal rhythms, for example by adding a single cymbal at the
end or changing the drum tone in a pattern. You can also save edited rhythms to the instrument as well as to floppy disks.

76-note lower keyboard for plenty of range

The 76-note range can be split into zones, allowing a solo voice, pedal bass voice, percussion, etc., to be played
independently for an even wider range of performance possibilities. Since the lower keyboard can be divided into a
maximum of four parts, you have at your command expressive power that rivals that of a three-manual organ.
In addition, you can use the Drums/SFX function to play drum sounds or sound effects from the entire lower keyboard.

Notation display in the LCD screen

The large LCD screen allows recorded data or loaded music data to be displayed as a notation. You can enjoy the
convenience of playing from a notation, or checking the notation of a song you recorded.
Furthermore, the instrument features a color LCD panel for great visibility and comfortable operation.

Video output of lyrics

You can connect a television to view the lyrics from SMF music files.

Before You Start Playing

Using Headphones

The AT-90SL features a Phones jack. This allows you to play
without having to worry about bothering others around you,
even at night.

fig.00-29

Connect your headphones to the [Phones] jack

1.

underneath the left side of the keyboard.

The sound from the built-in speakers stops.

Now, sound is heard only through the headphones.

fig.00-30

Using a Microphone

The AT-90SL is equipped with a Mic jack.
Since this instrument has a Mic In jack, you can use a

microphone to enjoy a variety of possibilities such as singing
along with your performance, or singing along with SMF
music files (sold separately).

fig.00-32

1.

Connect your microphone to the [Mic In] jack
underneath the left side of the keyboard.

2.

Use the [Mic Volume] knob to adjust the volume
level for the microphone.

Phones

Adjust the headphones volume with the [Master

2.

Volume] slider and Expression pedal.

Accepts connection of Stereo headphones.

Some Notes on Using Headphones

fifig.00-31

• To prevent damage to the cord, handle the headphones
only by the headset or the plug.

• Headphones may be damaged if the volume is too high
when they are plugged in. Lower the volume on the AT­90SL before plugging in headphones.

• 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.

You can adjust the depth of the echo applied to sound from
the microphone (p. 195).

The microphone must be purchased separately. When
purchasing a microphone, please consult the vender where
you bought the AT-90SL.

NOTE

If the Input switch is set to “RSS,” RSS reverb will be applied
to the sound from the microphone. You can use the [Mic
Volume] knob to adjust the microphone volume (p. 210).

Some Notes on Using a Microphone

fig.00-31

• To avoid disturbing others, be careful of the volume
level when playing late at night or very early in the
morning.

• When connecting a microphone to the AT-90SL, 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.

• 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 the microphone so it is farther from the

speakers.

• Lowering volume levels.
