Roland USB MIDI Interface Owner’s Manual

Roland USB MIDI Interface

What is MIDI?

MIDI is an internationally recognized standard for exchanging performance information between electronic musical instruments and computers.

For example, in the illustration below, a MIDI signal meaning “the ‘C’ key on the MIDI keyboard was pressed” passes through the UM-ONE and is received by the computer’s software sound module, and then the software sound module plays the note “C.”

In this way, MIDI is used to send performance information to other instruments; for example “the ‘C’ key was pressed with a certain amount of force,” “the instrument was changed to a violin sound,” “the volume was raised/lowered,” “the pitch was raised/lowered,” etc. In other words, MIDI is the “language of musical instruments.”

MIDI signals are merely performance instructions, therefore a MIDI sound module, such as a software sound module, is required to produce sound.

All software sound modules and DAW (Digital Audio Workstation) software support MIDI.

* DAW software is a term that refers to music production software, such as SONAR

Note
Do not connect the UM-ONE to the computer until the driver has been installed ( Check down below )

Before using this unit, carefully read the sections entitled: “USING THE UNIT SAFELY” and “IMPORTANT NOTES” ( Check down below ). These sections provide important information concerning the proper operation of the unit. Additionally, in order to feel assured that you have gained a good grasp of every feature provided by your new unit, this Owner’s Manual should be read in its entirety. The manual should be saved and kept on hand as a convenient reference.

ALWAYS OBSERVE THE FOLLOWING

WARNING

  • Do not open or perform any internal modifications 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 install the unit in any of the following locations.

  • Subject to temperature extremes (e.g., direct sunlight in an enclosed vehicle, near a heating duct, on top of heat-generating equipment); or are

  • Damp (e.g., baths, washrooms, on wet floors); or are

  • Exposed to steam or smoke; or are

  • Subject to salt exposure; or are

  • Humid; or are

  • Exposed to rain; or are

  • Dusty or sandy; or are

  • Subject to high levels of vibration and shakiness.

WARNING

  • Do not place containers containing liquid on this product. Never allow foreign objects (e.g., flammable objects, coins, wires) or liquids (e.g., water or juice) to enter this product. Doing so may cause short circuits, faulty operation, or other malfunctions.

  • Immediately disconnect the USB cable, and request servicing by your retailer, the nearest Roland Service Center, or an authorized Roland distributor, as listed on the “Information” page when:

  • Objects have fallen into, or liquid has been spilled onto the unit; or

  • If smoke or unusual odor occurs

  • 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!)

WARNING

  • DO NOT play a CD-ROM disc on a conventional audio CD player. The resulting sound may be of a level that could cause permanent hearing loss. Damage to speakers or other system components may result

CAUTION

  • 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.

  • Disconnect all cords coming from external devices before moving the unit.

IMPORTANT NOTES

Placement

  • 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.
  • 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.

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 its jacks and connectors. Rough handling can lead to malfunctions.
  • 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.
  • 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 CDs

  • Avoid touching or scratching the shiny underside (encoded surface) of the disc. Damaged or dirty CD discs may not be read properly. Keep your discs clean using a commercially available CD cleaner.
