IMPORTANT NOTES
In addition to the items listed under Safety Precautions inside the front cover, please read and observe the following:
Power Supply
@ Before connecting this unit to other devices, turn off
the power to all units; this will help prevent damage
or malfunction.
@ Do not use this unit on the same power circuit with
any device that will generate line noise; an electric
motor or variable lighting system for example.
Placement
@ This device may interfere with radio and television
reception. Do not use this device in the vicinity of
such receivers.
O Observe the following when using the unit's disk
drive. For further details, refer to “Before Using
Disks”.
O Do not place the unit near devices that produce a
strong magnetic field (eg., loudspeakers).
O Install the unit on a solid, level surface.
O Do not move the unit or subject it to vibration
while the drive is operating.
O Make sure you always have the instrument placed so
it is level and sure to remain stable. Otherwise, if
played while tilted, you risk causing damage to the
keyboard as a result of the unnatural degree of force
that might be applied to certain parts of it.
Maintenance
O For everyday cleaning wipe the unit with a soft, dry
cloth or one that has been slightly dampened with
water. To remove stubborn dirt, use a mild, non-abra-
sive detergent. Afterwards, be sure to wipe the unit
thoroughly with a soft, dry cloth.
O Never use benzene, thinners, alcohol or solvents of
any kind, to avoid the possibility of discoloration
and/or deformation.
Memory Backup
@ Please be aware that the contents of memory may at
times be lost; when the unit is sent for repairs or
when by some chance a malfunction has occurred.
Important data should be stored on a floppy disk, or
written down on paper (if 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.
Additional Precautions
O Protect the unit from strong impact.
@ Never strike or apply strong pressure to the display.
@ A small amount of heat will radiate from the unit
during normal operation.
O Before using the unit in a foreign country, consult
with qualified service personnel.
@ Be careful that the bench lid does not pinch your
hand.
m General MIDI System
The General MIDI System is a set of recommendations
which seek to provide a way for going beyond the limi-
tations of proprietary designs, and standardize the
MIDI capabilities provided by sound generating
devices.
If you use a sound generating unit which carries the
General MIDI logo, you will be able to faithfully repro-
duce any song data which also carries the General MIDI
logo.
GS Format
The GS Format is Roland’s universal set of specifica-
tions which were formulated in the interest of standard-
izing the way in which sound generating devices will
operate when MIDI is used for the performance of
music. If you use a sound generating unit which carries
the GS logo, you will be able to faithfully reproduce any
commercially available song data which also carries the
GS logo.
This product supports both General MIDI and GS.
Song data which carries either of these logos can be
accurately reproduced.
SMF
This device can playback Standard MIDI Files (720
Kbyte format, 3.5 inch floppy disk) such as SMF Music
Data.

1. Detach the pedal cable that is temporarily fas-
tened by a fastener to the board on the upper
part of the expression pedal.
. Connect the pedal cable to the connector located
at the right side of the pedal board.
. Press the pedal board firmly all the way back so
that it no longer moves.
Do not remove the fastener. Before transporting
the AT-90, be sure to bundle the pedal cable so
that there is no slack, and fasten it to the fasten-
er.
BEFORE
YOU
BEGIN
Attaching the pedal board
Connecting the Power Cord
1. First, make sure that the Power switch at the
panel's left side is OFF (not pushed in).
. Connect the supplied power cord to the AC
Inlet connector, then plug the other end into an
AC outlet.
Only use the power cord supplied with this
instrument.
Whenever you do not intend to use the instru-
ment for extended periods of time, pull out the
power cord from the AC outlet.
Setting up the music stand
<> Lift the music stand, and adjust the metal joints
as shown in the illustration below.
Opening the cover
<> To open the cover, hold it with both hands and
lift it straight up. Then, slide it to the rear.
To close the cover, slowly pull it forward until it
stops. Then, gently lower it into place.
Be careful not to get your fingers caught when
opening or closing the cover. Adult supervision
is recommended when small children are going
to be using the instrument.
Make sure you don't have anything (such as
sheet music) on the keyboard when you close
the cover.

the
location
of
the
Microphone
relative
to
the
Y AT-90. If this occurs, change the direction of the
Microphone, or lower the Mic volume.
Using the output jacks
Connect here when you want your music to be
sounded by a keyboard amplifier or other audio
equipment. In addition, when you wish to
record what you play on the AT-90 onto a tape
recorder, connect a cable from here to the input
jacks on your tape recorder.
Because sound will no longer be output from
the AT-90's speakers when you connect head-
phones, you can practice even late at night with-
out disturbing others.
The volume level heard through headphones
can be adjusted with either the Master Volume
slider or the expression pedal.
Be careful, though, since excessive volume lev-
els can cause damage to your hearing.
* Becareful to avoid pulling the headphone cable.
Applying excessive force will cause malfunc-
tions.
Using a Microphone Using the input jacks
Connect a tape recorder or CD player here, and
their sound will also be heard from the internal
speakers along with what you play on the AT-
90. This conveniently allows you to practice
along with your favorite music.
1. Make sure that the Mic Volume control is low-
ered, then connect the Microphone to the Mic In
jack.
2. Adjust the Microphone volume and the amount
of echo using the Volume and Echo controls,
respectively.
You can enjoy singing as you play the AT-90, or
singing along while music data (SMF Music Data,
etc.: sold separately) is played back (p.44).
12

Turning on the light
+ After turning on the power, turn on the
Illumination switch (located at the bottom left of
the keyboard).
Illumination
Lights will illuminate in three locations; the
music stand, front panel, and the pedal board.
Cautions when using illumination
When illumination is used for an extended peri-
od, the light bulbs and the metal parts near the
light bulb (see diagram below) will become hot.
Be careful not to touch your hand or leg on
these areas. In particular, be careful of the fol-
lowing four locations.
1. Inside the music stopper
Do not insert your hand from below.
2. Panel illumination light bulb
Do not touch the light bulb or nearby parts.
When closing the lid, be sure to hold the han-
dles.
3. Bulb cover under the keyboard (foot area)
The entire cover will become hot. Be careful not
to touch your leg to this area.
4. Metal portion of lid
After closing the lid, do not touch this area.
Restoring all the factory default settings
Perform the procedure below to return all the
Settings of the AT-90 to those preset by the fac-
tory (when the instrument was new).
* Make sure there is no floppy disk in the disk
drive before carrying out the procedure.
* Turn on the power while holding down the One
Touch Program button.
One Touch

O
* When you are using the instrument for the very
first time, or it has remained unused for about a
month or so, it will automatically be returned to
the factory default settings when the power
turned on.

to 3 voices. Voices can be selected for the lower keyboard in the same way as for the
upper keyboard.

Footage Tablets
Upper and Lower provide Footage Tablets that allow you to create a wide variety of
sounds by combining voices of different pitches. Here’s how to use the Footage
Tablets to create a voice, so that you can play sounds that are not provided by the
three Parts discussed earlier.
So that you can easily hear the characteristics of the Footage Tablets, turn off the
voices of the three (four) parts “Organ,” “Symphonic” and "Orchestral" (& Solo).
