Power Supply: Use of Batteries

• 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.
• The AC adaptor will begin to generate heat after long hours of consecutive use. This is normal, and is not a cause for concern.
• 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.

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.
• 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.
• 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. Excessive heat can deform or discolor the unit.
• 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.
• 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.

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 impregnated 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

• 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.
• 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).
• When you need to transport the unit, package it in the box (including padding) that it came in, if possible. Otherwise, you will need to use equivalent packaging materials.

Handling Floppy Disks

- 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^ (50 to 122^ ).

- 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 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.

- 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.

Using USB Memory

- Carefully insert the USB memory all the way in—until it is firmly in place.

- Never touch the terminals of the USB Memory. Also, avoid getting the terminals dirty.

- USB Memory are constructed using precision components; handle the cards carefully, paying particular note to the following.

- To prevent damage to the cards from static electricity, be sure to discharge any static electricity from your own body before handling the cards.

- Do not touch or allow metal to come into contact with the contact portion of the cards.

- Do not bend, drop, or subject cards to strong shock or vibration.

- Do not keep cards in direct sunlight, in closed vehicles, or other such locations (storage temperature: -25 to 85° C).

- Do not allow cards to become wet.

- Do not disassemble or modify the cards.

Handling CD-ROMs

- 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.

* Visit the Roland website to check CD drive operation information. http://www.roland.com/

What are Music Files?

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.

Regarding Copyright

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.

The MT-90U Allows You To Use the Following Music Files

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.

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.

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.

General MIDI 2

The upwardly compatible General MIDI 2 recommendations pick up where the original General MIDI left off, offering enhanced expressive capabilities and even greater 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.

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.

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.

Formatting the USB Memory

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.

* When you format the USB memory, all previous content is erased.
* If you are reusing a USB memory, make sure that the memory doesn't contain any data that you don't want to lose.
* 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.

1. Connect the USB memory to the MT-90U.
2. Press [4] while pressing the [ ] (Song) button.

The settings screen appears.

1. Press the [ (Bwd)] or [ (Fwd)] button until "Format Memory" appears.

The following screen appears.

1. Press the [+] button.

The following screen appears and the [▶ (Play)] button indicator flashes.

To cancel formatting and return to the previous screen, press the [ ] (Song)] button.

1. Press the [▶ (Play)] button to begin formatting.

"Formatting..." appears on the display. When formatting is finished the previous screen appears.

* If the power is turned off during formatting, do not remove the USB memory from the MT-90U. Doing so may damage the unit.

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.

1. Connect the MT-90U-formatted USB memory to the computer.
2. Copy music file files onto the USB memory.

When you connect the USB memory to the MT-90U, you can play the music file.

Some notes on copying music files

• Save music files in SMF format.
• Up to eight alphanumeric characters can be used in the file name.
• Make sure the file extension is ".MID." If the extension is incorrect or unspecified, the MT-90U will not recognize the file.
• Convert the SMF format to "0." If format 1 is used, the file may not play normally.

- If you copy music files all at once from the computer to the USB memory, the song order may change. When you want save files on the USB memory in song order, copy the music files one at a time in the order that you want.

NOTE The MT-90U may not be able to play files that are too large.

NOTE Roland does not guarantee restoration and disclaims any responsibility for the loss of data while using the MT-90U.
