USING THE UNIT SAFELY 30

IMPORTANT NOTES 30

Before using this unit, carefully read USING THE UNIT SAFELY and IMPORTANT NOTES (leaflet USING THE UNIT SAFELY and Owners Manual (p. 30)). After reading, keep the document(s) including those sections where it will be available for immediate reference.

5 Thanks to 32-bit high-precision processing at a 96 kHz sampling rate from input to output, the MD-500 gives you stunningly high-quality modulation effect.

5 With an easily readable screen and an independent [TAP/CTL] switch, it delivers both high functionality as well as ease of use during live performances.

5 Standard effects such as chorus, flanger, and phaser have been enhanced using cutting-edge Boss technology. The MD-500 provides a total of 12 modulation effects, including models of the Boss CE-1 and scanner vibrato.

5 The memory function lets you store and recall 297 different setups from internal memory.

5 The MD-500 provides simul mode which lets you use two effects simultaneously, and an insert loop function which lets you shape your sound in conjunction with an external effect unit.

5 By connecting the MD-500 via a USB cable or MIDI cables, you can switch sounds and control parameters in synchronization with your computer DAW or an external MIDI device.

Getting Ready

Installing the Batteries Install four alkaline batteries (AA, LR6) in the battery compartment located on the bottom of the unit.

* When turning the unit over, be careful so as to protect the buttons and knobs from damage. Also, handle the unit carefully; do not drop it.

* If you handle batteries improperly, you risk explosion and fluid leakage. Make sure that you carefully observe all of the items related to batteries that are listed in USING THE UNIT SAFELY and IMPORTANT NOTES (separate sheet USING THE UNIT SAFELY and Owners manual (p. 30)).

* We recommend that you keep batteries installed in the unit even though youll be powering it with the AC adaptor. That way, youll be able to continue a performance even if the cord of the AC adaptor gets accidently disconnected from the unit.

* BATTERY LOW will appear on the display if the batteries are low. Replace them with new ones.

Attaching the Rubber Feet You can attach the rubber feet (included) if necessary. Attach them in the locations shown in the illustration.

Connecting the Equipment * To prevent malfunction and equipment failure, always turn down the volume, and turn off all

the units before making any connections.

DC IN jack Accepts connection of an AC Adaptor (PSA-S series; sold separately). By using an AC Adaptor, you can play without being concerned about how much battery power you have left.

* Use only the specified AC adaptor (PSA-S series; sold separately), and connect it to an AC outlet of the correct voltage. Do not use any other AC adaptor, since this may cause malfunction.

* If the AC adaptor is connected while power is on, the power supply is drawn from the AC adaptor.

USB (O) port Use a commercially available USB 2.0 cable to connect this port to your computer. You can synchronize with a DAW via MIDI.

MIDI IN, OUT connectors Connect an external MIDI device here. You can synchronize with an external MIDI device via MIDI.

CTL 1, 2/EXP jack You can control various parameters by connecting a footswitch (FS-5U, FS-5L, FS-6, FS-7: sold separately) or an expression pedal (such as the EV-30, Roland EV-5; sold separately) to the CTL 1, 2/EXP jack (p. 25).

When connecting expression pedal

OUTPUT A/MONO, B jacks Connect these jacks to your amp or monitor speakers. If youre using a mono setup, use only the OUTPUT A/ MONO jack.

* Do not connect headphones to the OUTPUT A/MONO, B jacks. Doing so may damage the headphones.

INPUT A/MONO, B jacks Connect your electric guitar, or another instrument or effect unit, to these jacks.

* Use the INPUT A/MONO jack and B jack when connecting a stereo- output effects unit. Use only the INPUT A/MONO jack if youre using a mono source.

Turning the power on/off The INPUT A/MONO jack doubles as the power switch. Power to the unit is turned on when you plug into the INPUT A/MONO jack; the power is turned off when the cable is unplugged. When powering up: Turn on the power to your amp last. When powering down: Turn off the power to your amp first.

MEMO You can connect an external effect unit and use it in conjunction with the MD-500s effects (p. 24).

Synchronizing with a DAW or External MIDI Device

MIDI Routing For details on how to set the MIDI parameters, refer to Basic [EDIT] operations (p. 8).

Main Setting Items Item Parameter Explanation

Synchronization source SYNC Specifies whether the synchronization source is the MD-500 (INTERNAL), USB, or an external device connected via MIDI.

Realtime messages REALTIME SRC Specifies whether realtime messages generated by the MD-500 are transmitted, and whether realtime messages received via the MIDI IN connector or the USB port are transmitted.

MIDI message output destination

MIDI IN->OUT Specifies the MIDI messages that are transmitted from the MIDI OUT connector.

USB IN->OUT Specifies the MIDI messages that are transmitted from the USB port.

If you experience problems connecting with your DAW Normally, you dont need to install a driver in order to connect the MD-500 to your computer. However, if some problem occurs, or if the performance is poor, using the BOSS original driver may solve the problem. In this case, setting USB MODE to VENDOR on the MD-500, install the driver on your personal computer. For details on downloading and installing the BOSS original driver, refer to the BOSS website. For further details, refer to the Readme.htm file that comes with the download. & http://www boss info/support/ The program you need to use, and the steps you need to take to install the USB driver will differ depending on your computer setup, so please carefully read and refer to the Readme. htm file that comes with the download.

Troubleshooting Problem Items to check Action

Power does not turn on

Is your guitar correctly connected to the INPUT A/MONO jack? Check the connection once again.

Could the batteries be low? Install fresh batteries. Is the specified PSA-S series AC adaptor connected correctly? Check the connection once again.

No sound is output Could the insert loop function be assigned?

If the insert loop function is on, there will be no sound unless the external effect unit is correctly connected and its power is on (p. 24).

Footswitch does not change sounds as you expect

Is the SYSTEM: FSW MODE (p. 22) setting correct?

The FSW MODE (p. 22) setting determines what happens when you press the [A], [B], and [TAP/CTL] switches. Check the setting.
