careful when using extension
cords—the total power used
by all devices you have
connected to the extension

Important Notes
Power Supply: Use of Batteries
Maintenance
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.
•
401aFor 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 impregnated with a mild,
non-abrasive detergent. Afterwards, be sure to wipe the
unit thoroughly with a soft, dry cloth.
402
•
Never use benzine, thinners, alcohol or solvents of any
kind, to avoid the possibility of discoloration and/or defor-
mation.
302
Additional Precautions
•
The AC adaptor will begin to generate heat after long
hours of consecutive use. This is normal, and is not a cause
for concern.
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.
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.
554
•
Never strike or apply strong pressure to the display.
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.
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.
•
558aTo 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).
•
352aThis device may interfere with radio and television
•
559aWhen you need to transport the unit, package it in the box
reception. Do not use this device in the vicinity of such
receivers.
(including padding) that it came in, if possible. Otherwise,
you will need to use equivalent packaging materials.
•
352bNoise 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 initi-
ating 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.
•
354aDo 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.
Excessive heat can deform or discolor the unit.
•
355bWhen 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.
360
•
Depending on the material and temperature of the surface
on which you place the unit, its rubber feet may discolor or
mar the surface.
You can place a piece of felt or cloth under the rubber feet
to prevent this from happening. If you do so, please make
sure that the unit will not slip or move accidentally.

Important Notes
Handling Floppy Disks
Handling CD-ROMs
801
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:
•
Avoid touching or scratching the shiny underside (encoded
surface) of the disc. Damaged or dirty CD-ROM discs may
not be read properly. Keep your discs clean using a
commercially available CD cleaner.
•
•
•
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,
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.
fig.DiskProtect.e.eps
Rear side of the disk
Write
(can write new data onto disk)
Write Protect Tab
Protect
(prevents writing to disk)
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.

Use stereo headphones for the best sound.
Some notes on using headphones
• Make sure you handle the headphones, headphone cord, and jack appropriately to avoid
cord damage.
• When you connect your headphones, they can be damaged if the volume is set too high on
the device. Be sure to connect your headphones after turning the volume all the way down.
• Too much input into the headphones not only causes sound distortion and pain in your ears,
but also puts extra stress on the headphones. Be sure to use your headphones at an
appropriate volume.

MT-90U Basic Operation
When using the remote control
1. To use the remote control, point the remote control toward the MT-90U’s sensor and
operate it within the specified operating range.
The operating range is about 4 meters away from and 30 degrees to the right
and left of the sensor.
NOTE
Some notes on using the remote control
• The remote control does not function when two or more buttons are pressed at the same time.
• Even within the sensor range, the remote control may not function if something is obstructing
the sensor path, or if the remote is held at an awkward angle.
• Using the remote near other devices that use infrared rays, or using a remote other than the
one supplied with the MT-90U can cause malfunction.
• Battery life varies depending on how the remote is used. When the battery wears down, the
sensor range decreases. The battery should be replaced when this happens.
• If you are not going to use the remote control for a long period of time, take the battery out
and store it somewhere for use later.
• Shining a bright light, such as a spot light, on the remote sensor can decrease the sensor’s
responsiveness.
• Use only the specified type (model no. CR2025) of lithium battery. Be sure to insert it as
directed (to ensure correct polarity).
Tuning with the MT-90U
Match the pitches of the instruments you are using to a standard pitch with the MT-90U
for a beautiful, resonant sound. Matching instruments to a standard pitch is called
“tuning.”
What is standard pitch?
The middle A note (440Hz), also known as “concert A,” is the standard tuning pitch.
NOTE
You cannot use an audio file as the MT-90U’s standard pitch.

keyboard or pad controller, you can use the MT-90U (its built-
in instrumental sounds) as a sound module.
Connecting an External Audio
Device
By connecting the MT-90U to an external audio device, you
can listen to the MT-90U’s sounds through different audio
speakers or record a performance on a recording device such
as a tape recorder.
* When connecting an external MIDI device and using it to
operate the MT-90U, the device’s MIDI settings must be
specified. For details, refer to the owner’s manual that came
with the MIDI device.
Use a cable with RCA phono plugs, such as the PJ-1M (sold
separately), to connect to external audio devices.
What is MIDI?
The Musical Instrument Digital Interface (MIDI) is the
standardized protocol for communication between electronic
music devices and computers. Use a MIDI cable to connect
devices that have a MIDI connector, and you can send and
receive music files.

MIDI In Connector
You can connect to an external audio device with an audio
cable (sold separately) and play the MT-90U’s sounds through
the device’s speakers.
<fig.03-11.eps>
Rear Panel
When you are not using the MT-90U’s speakers, remember to
turn the speaker switch off.
Using a MIDI cable (sold separately), connect this with the
external device’s MIDI Out connector.
Connecting and Using a Digital Piano
The MT-90U receives MIDI data from the external MIDI device.
The MT-90U then performs operations in response to the
received data, such as playing notes or changing the sound
that’s used.
Connecting a digital piano
You can connect a digital piano and use its speakers to play
sounds from the MT-90U.
* To prevent malfunction and/or damage to speakers or other
devices, always turn down the volume, and turn off the
power on all devices before making any connections.
1. Connect the MT-90U’s Output L/R jacks on the
rear panel to the piano’s Input L/R jacks using
an audio cable (sold separately).
Sound from the MT-90U can now be heard through the
piano’s speakers.
2. Turn off the speaker switch on the MT-90U’s
rear panel.
The MT-90U’s speakers stop producing sound. Turn the
speaker switch on, and sound will be produced by the MT-
90U’s speakers.

About Music Files
What are Music Files?
General MIDI
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 meet the General MIDI standard bear 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.
Music files contain musical information such as how long a
pitch is played, the force applied to the key or note played,
and other such information. Performance data is transmitted to
the MT-90U from music files saved in USB memory, and
played back as songs. This is different from an audio CD,
since the music file does not contain a recording of the sound
itself. This makes it possible to change the tempo and key
freely, allowing you to use the data in many different ways.
General MIDI 2
Regarding Copyright
The upwardly compatible General MIDI 2 recommendations
pick up where the original General MIDI left off, offering
enhanced expressive capabilities and even greater
Use of the internal songs and audio files for any purpose other
than private, personal enjoyment without the permission of the
copyright holder is prohibited by law. Additionally, this data
must not be copied or used in a secondary copyrighted work
without the permission of the copyright holder. Please be
aware that if you create derivative works that are based on
existing copyrighted material, such as commercially available
SMF music files, such works may violate copyright law if used
for any purpose other than personal enjoyment. Roland takes
no responsibility for any copyright violation you may commit
by creating such works.
compatibility. Issues that were not covered by the original
General MIDI recommendations, such as how sounds are to
be edited, and how effects should be handled, have now been
precisely defined. Moreover, the available sounds have been
expanded. General MIDI 2 compliant sound generators are
capable of reliably playing back music files that carry either
the General MIDI or General MIDI 2 logo. In some cases, the
conventional form of General MIDI, which does not include the
new enhancements, is referred to as “General MIDI 1” as a
way of distinguishing it from General MIDI 2.
The MT-90U Allows You To
Use the Following Music Files
GS Format
The GS Format is Roland’s set of specifications for
standardizing 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 General
MIDI, Roland’s GS Format is capable of reliably playing back
GM Scores equally as well as it plays back music files that
have been specifically created with the GS Format.
VIMA TUNES
VIMA TUNES is a Roland specification for music files that
contain image and lyric data, allowing you to enjoy songs
with lyrics and images simultaneously. When data bearing the
“VIMA TUNES” logo is played back on a device that bears
the same logo, lyrics can be shown on the screen of a
connected external display or television, letting you enjoy
karaoke or watch a slide show.
* This unit (MT-90U) cannot play back VIMA TUNES images.
SMF Music Files
SMFs (Standard MIDI Files) use a standard music file format
that was formulated so that media containing music files could
be widely compatible, regardless of the manufacturer of the
listening device. An enormous variety of music is available,
whether it be for listening, practicing musical instruments, or
karaoke, etc.
XGlite
XG is YAMAHA Corporation’s tone generator format. It
defines the ways in which voices are expanded or edited,
along with the structure and type of effects, in addition to the
General MIDI 1 specification. XGlite is a simplified version of
XG tone generation format. You can play back any XG music
files using an XGlite tone generator. However, keep in mind
that some music files may play back differently compared to
the original files, due to the reduced set of control parameters
and effects.
SMF with Lyrics
“SMF with Lyrics” refers to a SMF (Standard MIDI File) that
contains lyrics. When Music Files carrying the “SMF with
Lyrics” logo are played back on the MT-90U, the lyrics will
appear in its display.

About Music Files
Formatting the USB Memory
Copying Music Files from a
Computer to USB Memory
You can copy music files from a computer to USB memory and
play them on the MT-90U.
Setting up USB memory so that it is compatible for use on the
MT-90U is called formatting. If the USB memory and MT-90U
format do not match, you cannot use the USB memory with the
unit. You need to format new USB memory before using it with
the MT-90U.
We recommend using Roland USB memory. We cannot
guarantee that other commercially available USB memory will
operate correctly with the unit.
1. Connect the MT-90U-formatted USB memory
to the computer.
2. Copy music file files onto the USB memory.
* When you format the USB memory, all previous content is
erased.
When you connect the USB memory to the MT-90U, you can
play the music file.
* If you are reusing a USB memory, make sure that the memory
doesn’t contain any data that you don’t want to lose.
Some notes on copying music files
* USB memory that you have formatted with a computer may not
work with the MT-90U. For this reason, make sure you format the
USB memory with the MT-90U before using it.
• Save music files in SMF format.
• Up to eight alphanumeric characters can be used in the
file name.
1. Connect the USB memory to the MT-90U.
• Make sure the file extension is “.MID.” If the extension is
incorrect or unspecified, the MT-90U will not recognize
the file.
2. Press [4] while pressing the [
(Song)
button.
• Convert the SMF format to “0.” If format 1 is used, the file
may not play normally.
The settings screen appears.
