•Before using this unit, make sure to read
the instructions below, and the Owner’s
Manual.
........................................................................
•Do not open or perform any internal mod-
ifications on the unit.
........................................................................
•Do not attempt to repair the unit, or
replace parts within it (except when this
manual provides specific instructions
directing you to do so). Refer all servicing
to your retailer, the nearest Roland
Service Center, or an authorized Roland
distributor, as listed on the “Information” page.
........................................................................
•Never use or store the unit in places that
are:
•Subject to temperature extremes (e.g.,
direct sunlight in an enclosed vehicle,
near a heating duct, on top of heat-gen-
erating equipment); or are
•Damp (e.g., baths, washrooms, on wet
floors); or are
•Humid; or are
•Exposed to rain; or are
•Dusty; or are
•Subject to high levels of vibration.
........................................................................
•Make sure you always have the unit
placed so it is level and sure to remain sta-
ble. Never place it on stands that could
wobble, or on inclined surfaces.
........................................................................
•The unit should be connected to a power
supply only of the type described in the
operating instructions, or as marked on
the rear side of unit.
........................................................................
•Use only the attached power-supply cord.
........................................................................
•Do not excessively twist or bend the
power cord, nor place heavy objects on it.
Doing so can damage the cord, producing
severed elements and short circuits.
Damaged cords are fire and shock hazards!
•This unit, either alone or in combination
with an amplifier and headphones or
speakers, may be capable of producing
sound levels that could cause permanent
hearing loss. Do not operate for a long period of
time at a high volume level, or at a level that is
uncomfortable. If you experience any hearing loss
or ringing in the ears, you should immediately
stop using the unit, and consult an audiologist.
........................................................................
•Do not allow any objects (e.g., flammable
material, coins, pins); or liquids of any
kind (water, soft drinks, etc.) to penetrate
the unit.
........................................................................
•Immediately turn the power off, remove
the power cord from the outlet, and
request servicing by your retailer, the
nearest Roland Service Center, or an
authorized Roland distributor, as listed on
the “Information” page when:
•The AC adaptor, the power-supply cord, or the
plug has been damaged; or
•If smoke or unusual odor occurs
•Objects have fallen into, or liquid has been
spilled onto the unit; or
•The unit has been exposed to rain (or otherwise
has become wet); or
•The unit does not appear to operate normally or
exhibits a marked change in performance.
........................................................................
•In households with small children, an
adult should provide supervision until the
child is capable of following all the rules
essential for the safe operation of the unit.
........................................................................
•Protect the unit from strong impact.
(Do not drop it!)
........................................................................
•Do not force the unit’s power-supply cord
to share an outlet with an unreasonable
number of other devices. Be especially
careful when using extension cords—the total
power used by all devices you have connected to
the extension cord's outlet must never exceed the
power rating (watts/amperes) for the extension
cord. Excessive loads can cause the insulation on
the cord to heat up and eventually melt through.
........................................................................
•Before using the unit in a foreign country,
consult with your retailer, the nearest
Roland Service Center, or an authorized Roland
distributor, as listed on the “Information” page.
•Do not put anything that contains water
(e.g., flower vases) on this unit. Also,
avoid the use of insecticides, perfumes,
alcohol, nail polish, spray cans, etc., near
the unit. Swiftly wipe away any liquid
that spills on the unit using a dry, soft cloth.
•The unit should be located so that its loca-
tion or position does not interfere with its
proper ventilation.
........................................................................
•Always grasp only the plug on the power-
supply cord when plugging into, or
unplugging from, an outlet or this unit.
........................................................................
•At regular intervals, you should unplug
the power plug and clean it by using a dry
cloth to wipe all dust and other accumula-
tions away from its prongs. Also, disconnect the
power plug from the power outlet whenever the
unit is to remain unused for an extended period of
time. Any accumulation of dust between the
power plug and the power outlet can result in
poor insulation and lead to fire.
........................................................................
•Try to prevent cords and cables from
becoming entangled. Also, all cords and
cables should be placed so they are out of
the reach of children.
........................................................................
•Never climb on top of, nor place heavy
objects on the unit.
........................................................................
•Never handle the power cord or its plugs
with wet hands when plugging into, or
unplugging from, an outlet or this unit.
........................................................................
•Before moving the unit, disconnect the
power plug from the outlet, and pull out
all cords from external devices.
........................................................................
•Before cleaning the unit, turn off the
power and unplug the power cord from
the outlet (p. 18).
........................................................................
•Whenever you suspect the possibility of
lightning in your area, pull the plug on the
power cord out of the outlet.

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
• Do not use this unit on the same power circuit with
any device that will generate line noise (such as an
electric motor or variable lighting system).
• Before connecting this unit to other devices, turn off
the power to all units. This will help prevent mal-
functions and/or damage to speakers or other
devices.
• 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
• 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.
• This device may interfere with radio and television
reception. Do not use this device in the vicinity of
such receivers.
• Observe the following when using the unit’s floppy
disk drive. For further details, refer to “Before Using
Floppy Disks” (p. 5).
• 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.
• 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 tempera-
ture extremes. Excessive heat can deform or discolor
the unit.
• To avoid possible breakdown, do not use the unit in
a wet area, such as an area exposed to rain or other
moisture.
Maintenance
• 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 cloth impreg-
nated with a mild, non-abrasive detergent.
Afterwards, be sure to wipe the unit thoroughly
with a soft, dry cloth.
• Never use benzine, thinners, alcohol or solvents of
any kind, to avoid the possibility of discoloration
and/or deformation.
Additional Precautions
• 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.
• 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.
• Never strike or apply strong pressure to the display.
• 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.
• A small amount of heat will radiate from the unit
during normal operation.
• 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 con-
cerned about those around you (especially when it is
late at night).
• When you need to transport the unit, package it in
the box (including padding) that it came in, if possi-
ble. Otherwise, you will need to use equivalent
packaging materials.
• 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 connect-
ing to this unit. The use of such cables can cause
the sound level to be extremely low, or impossi-
ble to hear. For information on cable specifica-
tions, contact the manufacturer of the cable.

IMPORTANT NOTES
4

Handling the Floppy Disk Drive
• Install the unit on a solid, level surface in an area
free from vibration. If the unit must be installed at
an angle, be sure the installation does not exceed the
permissible range.
• 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.
• 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.
• Never attempt to remove a floppy disk from the
drive while the drive is operating (the indicator is
brightly lit); damage could result to both the disk
and the drive.
• Remove any disk from the drive before powering up
or down.
• 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 exces-
sive force.
• 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
• Floppy disks contain a plastic disk with a thin coat-
ing of magnetic storage medium. Microscopic preci-
sion 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 vehi-
cle). 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.
• Floppy disks have a “write protect” tab which can
protect the disk from accidental erasure. It is recom-
mended that the tab be kept in the PROTECT posi-
tion, and moved to the WRITE position only when
you wish to write new data onto the disk.
• 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.
• 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.
• 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” posi-
tion), 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 ren-
dering the disk unreadable by this unit’s disk drive.

Thank you, and congratulations on your choice of the Roland MT 300s Music Player.
You can use the MT 300s not only on its own; by connecting a digital piano, you’ll
have even more ways to play sounds.
What You Can Do with the MT 300s as a Stand-Alone Machine
Listen to music files
Using the built-in disk drive, you can listen to songs in a wide variety of musical gen-
res formatted as music files (p.25).
Practice instruments
The MT 300s features a variety of convenient functions for changing song tempos
(p.33), practicing each hand’s part (p.38), playing back the same section of a song
repeatedly (p.31), and other functions useful for playing songs.
Perform accompanied by orchestral backing from music files
You can mute specific parts contained in music files and play those parts yourself
(p.38), or listen only to specific selected parts (p.60).
Enjoy karaoke
The MT 300s features a microphone input jack. You can also add echo, and change the
key of the accompaniment (p.54).
Your original performances using acoustic instruments cannot be recorded with the MT 300s.
What you can do with a digital piano connected:
Record your own performances
Just as with a regular tape recorder, you can record performances onto the five
Track/TRACK buttons (p.41).
Create authentic ensemble pieces
With so many different recording and performance functions, creating your own
songs is a snap (p.61, 78).
Save the songs you create to floppy disks, and then make and
copy original song collections.
Using the built-in disk drive, you can save recorded songs (p.49).
Perform with various instrument sounds played from a connected
keyboard.
The MT 300s includes an internal GS sound generator with a selection of over 300
sounds to choose from (p.55, 56).

Flashes in time with the beat of the song or the
Metronome.
2 Bouncing Ball
The “Bouncing Ball” is a ball-shaped icon that
moves in time with the rhythm of the song or
Metronome. By tracing a semicircular path as it
moves from beat to beat, it conveys an better under-
standing of rhythm than that obtained through a
mere series of dots, making it this a very useful fea-
ture.
3 Cursor
Symbols on the screen, including ( ) and ( ), are
known as cursors. You can move the cursors with
the Beat [ ] button or Tempo [ ] button.
You can change the values for items with cursor at
the beginning by using the [Dial].

To get even better sound
You can play the sound from the MT 300s through a digital piano’s speakers.
1. Using a commercially available audio cable, connect the Output R/L
jack of the MT 300s to the digital piano’s Input R/L jack.
This lets you play the sound from the MT 300s through the digital piano speakers as
well as from the MT 300s’s own speaker.
2. Flip the Speaker switch on the rear panel of the MT 300s to “Off.”
Sound from the MT 300s speaker now stops.
If you turn the Speaker switch back to “On,” sound will again come from the MT
300s’s speaker.
Please use an audio cable with a standard phone plug. Consult the retailer from whom you purchased the
MT 300s.
About the Pedal
fig.5-2_30
Using a pedal to start and stop playback and recording of songs
By connecting an optional pedal switch (such as Roland’s model DP-2) to the MT
300s’s Start/Stop jack, you can start and stop playback and recording of songs by
pressing on the pedal. Furthermore, you can begin and end songs with fade-ins and
fade-outs. Please refer to “Changing the Pedal Functions” (p.98).
Changing the volume with the pedal
By connecting an expression pedal (such as the Roland EV-5) to the MT 300s’s
Expression Pedal jack, you can change the volume of songs or sounds by stepping on
the pedal.
You cannot use the pedal switch if it is connected to the Expression Pedal jack; likewise, the expression
pedal cannot be used if it is plugged into the Start/Stop jack.
You will need to set up the Roland DP-2 Expression Pedal or EV-5 Expression Pedal separately. Please
consult the dealer where you purchased these products when using them with the MT 300s.
Use only the specified expression pedal (EV-5; sold separately). By connecting any other expression ped-
als, you risk causing malfunction and/or damage to the unit.

Adjusting the Volume
fig.7-1_30
1. Adjust the volume with the [Volume] slider.
Sliding the control to the right increases the volume, and sliding it to the left decreases
the volume.
Tuning the MT 300s to Electronic Keyboards
When using the MT 300s with a digital piano or other instrument connected, you first
have to tune the instruments’ standard pitches to each other.
If, while playing ensemble pieces with other instruments, the pitches do not match,
you will not be able to get pleasant sounding performances. Matching these standard
pitches is called “tuning.”
What is the standard pitch?
In general, the pitch at Middle A on the piano is what is referred to as the standard pitch.

Adding Reverberation to the Sound
You can select the method of applying reverberation to the MT 300s’s sound to suit
your particular needs.
What is the reverb effect?
Reverberation is provided by the reverb effect. Adding reverb lends the sound a pleasant reverberation
similar to that heard in a concert hall.
