Main features

Simple Operation—Works Like a Compact Effects Processor

Each effect is controlled with a dedicated knob.

Intuitive operation, similar to that of compact effects processors, lets you make changes to tones directly.

Powerful COSM Drive Sound

Roland's original "COSM" modeling technology lets you perform with a wide variety of powerful distortion effects, from classic vintage sounds, to original distortion sounds.

COSM (Composite Object Sound Modeling)

Composite Object Sound Modeling (COSM) is Roland's innovative and powerful sound modeling technology. COSM analyzes the many factors that make up the original sound, such as the electrical and physical characteristics of the original, and then produces a digital model that can reproduce the same sound.

Multi-Function Expression Pedal

The ME-50 is equipped with an expression pedal that gives you control over six different specialized pedal effects. It can also be switched for use as a volume pedal.

Memory Function

You can store up to 30 original tones you have created. You can also use the pedals in "Memory mode" to call up stored tones instantly.

AUX IN Jack

The AUX IN jack makes it easy to practice along with CDs, MDs, and other input.

Battery-Powered Operation

The ME-50 can be powered in two ways, with (6) AA batteries or by using the AC adaptor (optional).

BOSS ME-50 - CAUTION - 7

In addition to the items listed under "USING THE UNIT SAFELY" on page 2-3, please read and observe the following:

Power Supply: Use of Batteries

  • 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).
  • The AC adaptor will begin to generate heat after long hours of consecutive use. This is normal, and is not a cause for concern.
  • The use of an AC adaptor is recommended as the unit's power consumption is relatively high. Should you prefer to use batteries, please use the alkaline type.
  • When installing or replacing batteries, always turn off the power on this unit and disconnect any other devices you may have connected. This way, you can prevent malfunction and/or damage to speakers or other devices.
  • Batteries are supplied with the unit. The life of these batteries may be limited, however, since their primary purpose was to enable testing.
  • 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.

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

  • Please be aware that the contents of memory can be irretrievably lost as a result of a malfunction, or the improper operation of the unit. To protect yourself against the risk of loosing important data, we recommend that you periodically save a backup copy of important data you have written on the paper.
  • Unfortunately, it may be impossible to restore the contents of data that was stored in the unit's memory 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.
  • 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.
  • 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 connecting to this unit. The use of such cables can cause the sound level to be extremely low, or impossible to hear. For information on cable specifications, contact the manufacturer of the cable.

Adding an Effect Synchronized to the Performance Tempo

When any effect other than HARMONIST is selected, you can set the tempo so you get an effect that is synchronized to the performance tempo.

  • The allowable rate cycles for the tempo settings range from 62 ms to 2000 ms.

  • Hold down the MOD pedal for at least two seconds.

  • If the MOD pedal is pressed when the effect is on, the pedal indicator goes out, and the effect is turned off.

  • If the MOD pedal is pressed when the effect is off, the pedal indicator turns red, and the effect is turned on.

When you continue to depress the pedal, after two seconds the pedal's indicator starts to flash, and the tempo can then be set with the effect on.

Here, the tempo is indicated by the value set with the RATE/KEY knob.

  1. Press the MOD pedal in timing with the tempo more than two times.

The tempo is set according to the time interval between each press of the pedal. The pedal indicator flashes in time with the tempo.

MEMO

Setting the RATE near the desired tempo beforehand allows you to make faster and more natural tempo settings.

  1. Hold down the MOD pedal for at least two seconds to complete the tempo setting.

The effect goes on, and instead of flashing, the pedal indicator will light.

  • If you move the RATE/KEY knob after finishing this setting, the rate corresponding to the knob position takes effect.

DELAY

BOSS ME-50 - DELAY - 1

This effect adds delayed sound to the direct sound, giving more body to the sound or creating special effects.

DELAY pedal

The Delay is switched on or off each time you press the pedal. When switched on, the DELAY indicator and pedal indicator light up.

  • DELAY ON/OFF switches the Delay at the input to provide a more natural effect. For this reason, if the FEEDBACK is turned up when the Delay is turned off, the delay sound will remain briefly.

TYPE knob

Sets the type of the delay

  • When a setting other than HOLD is selected, you can use the DELAY pedal to input the tempo, and set the delay time synchronized to the performance tempo.

BOSS ME-50 - TYPE knob - 1

This gives a mild analog delay sound. The delay time can be set within the range of 100ms to 500ms .

SLOW ECHO

This produces an effect combining a volume-swell sound with delay. The delay time can be set within the range of 200 ms to 1000 ms.

PAN

A panned delay in which the repeated sounds come alternately from the left and right channels. The delay time can be set within the range of 200ms to 1000ms .

  • When using the ME-50 in mono, the panning delay is not effective, even when PAN is selected.

SPACE PAN

This is a panning delay that gives an even wider spatial effect than PAN. The delay time can be set within the range of 200 ms to 1000 ms.

  • When using the ME-50 in mono, or when using headphones, the panning delay is not effective, even when SPACE PAN is selected.

REVERSE

This produces an effect where the sound is played back in reverse.

You can get two different effects, "direct sound + effect sound," or "effect sound only," depending on the position of the E. LEVEL knob. When the E. LEVEL knob is turned up to MAX, the unit switches to "effect sound only."

The delay time can be set within the range of 400ms to 2000 ms.

HOLD

Up to 2 seconds of performance content is recorded, then played back repeatedly. You can also layer this as you perform something else, then record these together (overdub).

You can keep the recorded content playing continuously as backing and produce other special effects.

BOSS ME-50 - HOLD - 1

"Using the HOLD Function"

BOSS ME-50 - HOLD - 2

This is a tempo delay that lets you set a dotted eighth note delay time for the performance tempo by pressing the DELAY pedal in time with the performance tempo.

  • The delay time can be set within the range of 46.5 ms to 1500 ms.

  • Set the TYPE knob to "TAP"

The pedal indicator flashes in time with the current tempo.

  1. Press the DELAY pedal in timing with the tempo more than two times.

The reference tempo is determined by the time interval between each press of the pedal. The reference tempo is calculated in terms of quarter notes, and the delay time setting is the dotted eight note as referenced to the reference tempo.

The pedal indicator flashes in time with the tempo.

Adding a Delay Synchronized to the Performance Tempo

Using tempo input, the delay time can be set within the range of 62 ms to 2000 ms.

You can set this regardless of whether the effect is on or off.

  1. Select the delay type. (except HOLD, TAP)
  2. Hold down the DELAY pedal for at least two seconds.

  3. If the DELAY pedal is pressed when the effect is on, the pedal indicator goes out, and the effect is turned off.

  4. If the DELAY pedal is pressed when the effect is off, the pedal indicator turns red, and the effect is turned on.

When you continue to depress the pedal, after two seconds the pedal's indicator starts to flash, and the tempo can then be set with the effect on.

Here, the delay time is indicated by the value set with the TIME knob.

  1. Press the DELAY pedal in timing with the tempo more than two times.

The delay time is set according to the time interval between each press of the pedal.

The pedal indicator flashes in time with the tempo.

  • Press the pedal to set the tempo while no guitar sound is playing.
  • When the type is set to "PAN" or "SPACE PAN," the delay time is set to half the interval between the presses of the pedal.

  • Hold down the pedal switch for at least two seconds to complete the tempo setting.

The effect goes on, and instead of flashing, the pedal indicator will light.

  • The tempo may become confused momentarily when you go from Step 3 to Step 4.
  • If you move the TIME knob after finishing this setting, the delay time corresponding to the knob position takes effect.

Write Procedures (p. 21) When the Tempo Has Been Set

The delay time stored in a Patch (p. 20) is determined as follows.

  • If it is within the delay time range that can be set for the type currently selected, it is stored without change.
  • If it exceeds the maximum delay time that can be set for the type currently selected, the maximum value for the type is stored.
  • If it is less than the minimum delay time that can be set for the type currently selected, the minimum value for the type is stored.

(Example) When TYPE is 100-500 ms

When the delay time for the tempo setting is 600 ms: Stored as 500 ms.

When the delay time for the tempo setting is 80 ms: Stored as 100 ms.

Using the HOLD Function

  1. Set the TYPE knob to HOLD.

The unit goes into recording standby and the pedal's indicator flashes at a fixed interval.

  • After switching to HOLD, wait two seconds before you carry out the next operation.
  • Press the DELAY pedal to start recording.

Recording starts when you press the DELAY pedal. Hold down the pedal switch for the duration of the recording (the pedal indicator flashes).

  1. Release the DELAY pedal to stop recording.

Playback of the recorded content begins simultaneously (the CHECK indicator remains lit).

  • The maximum recording time is 2 seconds. If the DELAY pedal is held down for more than 2 seconds, the recording stops automatically, and the recorded content is then played back.
  • An oscillating sound may be audible with extremely short recording times.

  • When layering recordings, repeat Steps 2 and 3.

  • Adjust the volume

Adjust the volume of the playback sound with the E. LEVEL knob.

  1. Press the pedal switch to stop the playback (the pedal indicator goes out).

The unit returns to recording standby, and the pedal's indicator flashes at a fixed interval.

  • When playback is stopped, the recorded content is erased.
  • To start recording again, wait two seconds, then carry out step 2.

This effect reduces the noise and hum picked up by guitar pickups. Since it suppresses the noise in synchronization with the envelope of the guitar sound (the way in which the guitar sound decays over time), it has very little effect on the guitar sound, and does not harm the natural character of the sound.

THRESHOLD knob

Adjust this parameter as appropriate for the volume of the noise. If the noise level is high, a higher setting is appropriate. If the noise level is low, a lower setting is appropriate. Adjust this value until the decay of the guitar sound is as natural as possible.

  • Turn the knob to OFF when not using the noise suppressor. When switched OFF, the NS indicator goes out.
  • High settings for the threshold parameter may result in there being no sound when you play with your guitar volume turned down.

REVERB

BOSS ME-50 - REVERB - 1

This effect adds reverberation to the sound.

Use the knob to switch to any of four different reverb, ROOM, HALL, SPRING, or MOD. You can adjust the amount of effect applied according to the knob position.

  • The panel markings for ROOM, HALL, SPRING, or MOD are for approximate settings. Check the sound of the effects as you make adjustments.
  • The indicator is lit when Reverb is on, and goes off when Reverb is turned off.

ROOM

This simulates the reverb sound of a smaller room.

HALL

This simulates the reverb sound of a larger hall.

SPRING

This simulates the sound of a guitar amp's built-in spring reverb.

MOD

This is a reverb that adds modulation to the hall reverb to produce an extremely pleasant reverb sound.

Pedal

BOSS ME-50 - Pedal - 1

You can make the setting that determines whether the ME-50's expression pedal functions as a volume pedal or as an expression pedal. In addition, when using it as an expression pedal, you can use it to control one of the special pedal effects that you select.

Using the Pedal as a Volume Pedal

When using the expression pedal as a volume pedal, press the expression pedal all the way forward and then give it a stronger push, the PEDAL MODE indicator goes off.

BOSS ME-50 - Using the Pedal as a Volume Pedal - 1

The volume decreases as the pedal's toe is raised, and increases when the pedal is pressed down.

Using the Pedal as an Expression Pedal

When using the pedal as an expression pedal, press the expression pedal all the way forward and then give it a stronger push, the PEDAL MODE indicator lights up.

BOSS ME-50 - Using the Pedal as an Expression Pedal - 1

You can select one of the following effects with the expression pedal.

WAH

The effect will function as a pedal wah.

RESONANCE

This completely original effect offers enhancements on the characteristic resonances produced by analog synth filters. Using the effect in combination with the OVERDRIVE/ DISTORTION TYPE set to "SQUARE" produces a sound like a synthesizer.

And using it together with delay, chgorus, and reverb makes them even more effective.

VOICE

A further advancement beyond the BOSS HUMANIZER, this effect produces "talking" modulation sounds and realistic human voice sounds.

RING MOD

This is an effect that crosses the ME-50's internal oscillator with the guitar source sound to change the sound to a metallic sound devoid of any feeling of pitch.

Pressing the pedal down even more changes the internal oscillator's frequency, creating a particular undulation sound.

  • Because of the need to analyze the pitch, chords (two or more sounds played simultaneously) cannot be played.

+1 OCTAVE

Allows the pitch to be raised up to one octave above the original guitar sound.

  • Because of the need to analyze the pitch, chords (two or more sounds played simultaneously) cannot be played.

-1 OCTAVE

Allows the pitch to be lowered up to one octave below the original guitar sound.

  • Because of the need to analyze the pitch, chords (two or more sounds played simultaneously) cannot be played.

Saving and Loading the Created Tones (Memory Mode)

The ME-50 features a "Memory mode" that allows you to store the various settings within the ME-50 itself, and then call up and use the settings.

Switching Between Manual and Memory Mode

The mode in which the tone produced reflects the panel settings just as they are is called "Manual mode." A dot appears in the display when the ME-50 is in Manual mode.

BOSS ME-50 - Switching Between Manual and Memory Mode - 1

  • When switching from Manual mode to Memory mode, press the No. 2 and No. 3 pedals simultaneously; this causes the MEMORY indicator to light up (and the dot in the display disappears).

BOSS ME-50 - Switching Between Manual and Memory Mode - 2

BOSS ME-50 - Switching Between Manual and Memory Mode - 3

  • Pressing the No. 2 and 3 pedals at the same time while in Memory mode switches you to Manual mode.
  • Manual mode is the power-up default mode of the ME-50.

About the Patch

When actually performing on a guitar, a variety of tones are required to suit whatever the situation may be. The effects that you may want to have turned on and parameter settings for such effects vary according to the selected tone.

With the ME-50, you can set these parameters, volume levels, and so on, store a number of the aggregate settings in memory, and use the pedals to switch the stored settings, allowing you to change tones instantly.

Such stored sets of settings are known as "Patches." You can create up to 30 Patches.

The thirty patches are divided into ten "banks," each of which contains three patches.

BOSS ME-50 - About the Patch - 1

  • The setting for the MASTER LEVEL knob is also stored individually for each patch.

Write Procedure

The "Write procedure" enables you to save the created tone settings using the panel knobs and pedals, MASTER LEVEL knob setting, and expression pedal settings to Patches.

  • You can carry out the Write procedure in both Manual mode and Memory mode.
  • If the Write procedure is not carried out, then the tone you have created is erased when the power is turned off or when you switch to a different Patch.

BOSS ME-50 - Write Procedure - 1

1. Press [WRITE].

The MEMORY indicator flashes. At the same time, the bank indication in the display and the pedal indicator flash, and the currently selected Patch Bank and Number are shown.

2. Select the Patch to be used as the save destination.

Press BANK[ ] [ ] to select the bank.
Press a number pedal (1-3) to select the number.

  • To stop the Write procedure, press [EDIT/EXIT], and return to the previous mode.

3. Press [WRITE] once more.

The tone is stored, and Memory mode is then enabled (the MEMORY indicator lights up).

  • When a Write procedure is performed while the DELAY type is set to "TAP" (p. 16) and DELAY is on, after the operation the indicator for the number pedal where the tone was stored flashes to indicate that you can input the tempo.
  • When a Write procedure is carried out while the DELAY type is set to "HOLD" (p. 16), after the operation the indicator for the number pedal where the tone was stored flashes at a fixed interval to indicate that recording standby is enabled.

BOSS ME-50 - Press [WRITE] once more. - 1

The tone stored in the patch designated as the save destination is erased once the Write procedure is executed.

Calling Up and Using Stored Tones (Patch Change)

To switch patches, use BANK [ ] [ ] and the number pedals (1-3).

  • Bank 1, Number 1 is always selected at first when Memory mode is entered after the power is turned on.

Switching Numbers

When the number pedal (1) is pressed, the number indicator (2) above the pedal lights up, the patch with that number in the currently selected group and bank is called up, and the tone is switched instantly.

BOSS ME-50 - Switching Numbers - 1

Switching Banks

The bank is switched each time the BANK [] [] (1) is pressed. The currently selected bank flashes in the Display (2). (At this time, tones are not yet switched.)

  • You can switch among ten banks 1-0.

While in this state, if you press any of the number pedals (3), the tone instantly switches to the sound of the patch at the currently selected bank/number.

Notes When Using Memory Mode

About Tone Changes

By operating the knobs, you can change the tone of a patch while it's called up. Note, however, that the changed tone is only temporary, and will be lost when you switch patches or switch to the Tuner mode (p. 24).

If you want to store it in memory, carry out the Write procedure (p. 21).

  • If there is a discrepancy between the current knob position and the parameter stored in the patch, the change in the parameter begins at the point when the knob is moved past the position matching the parameter value as stored in the patch.
  • In Memory mode, you cannot switch effects on or off using the No. 1, 2, and 3 pedals.

About the Tempo Setting

If you hold down the currently selected number pedal for at least two seconds, the pedal indicator flashes, and the ME-50 switches to tempo setting mode, and the number pedal can then be used to input the tempo.

The unit functions as follows depending on the on/off status of MODULATION and DELAY.

  • When DELAY and MODULATION are both off, you cannot change to tempo setting mode.

When DELAY is ON (but TYPE is not set to HOLD or TAP).

You can use the tap input to set the delay time.

  • If both DELAY and MODULATION are on, only the delay can be set.

When MODULATION is ON

You can set the RATE for the effect selected with the TYPE knob (except for HARMONIST).

Note, however, that the tempo setting is only temporary, and will be lost when you switch patches or switch to the Tuner mode (p. 24).

If you want to store it in memory, carry out the Write procedure (p. 21).

About the DELAY HOLD

When DELAY is ON and a Patch that has a TYPE setting of HOLD is called up, the pedal indicator flashes slowly, indicating that the ME-50 is in recording standby. Afterwards, the following conditions are in effect.

  • Holding down the number pedal: begins recording
  • Releasing the number pedal: stops recording, starts Loop Playback
  • Continuing to press the pedal over and over: overdub recording
  • Pressing the Pedal rapidly; releases the HOLD, switches to recording standby

DELAY TAP

When DELAY is ON and a Patch that has a TYPE setting of TAP is called up, the pedal indicator flashes, and you can then set the delay time (p. 16) using tap input.

Changing the Patch Settings (Patch Edit mode)

Use the following procedure when editing the settings of a Patch you have called up.

BOSS ME-50 - Changing the Patch Settings (Patch Edit mode) - 1

  1. Switch to the Patch whose settings you want to edit (p. 21).
  2. Press [EDIT/EXIT].

The MEMORY indicator flashes, and editing of the Patch settings is enabled (Patch Edit mode).

  1. Use the knobs and pedals to change the settings.

When settings are changed, the indicator for the changed effect flashes (except for MASTER LEVEL).

When the OVERDRIVE/DISTORTION type is changed to VARIATION, the [VARIATION] indicator flashes.

  • If there is a discrepancy between the current knob position and the parameter stored in the patch, the change in the parameter begins at the point when the knob is moved past the position matching the parameter value as stored in the patch.

  • If you want to save the contents of your edit, carry out the Write procedure. (p. 21)

  • Pressing [EDIT/EXIT] switches you to Memory mode without saving the settings.

  • When the unit is not in Patch Edit mode, you cannot switch the following effects on or off.

OVERDRIVE/DISTORTION
- MODURATION

BOSS ME-50 - Tuning the Guitar (Tuner) - 6

One useful technique that makes tuning less confusing is to start slightly under the target pitch and then tune upwards little by little until the string is in tune.

  • When tuning guitars equipped with tremolo arms, you may find that after tuning one string, other strings may go out of tune. In such instances, first do a rough tuning of each string in order to get them close to their respective notes, then repeat with the fine-tuning of each string.

7. Press [EDIT/EXIT] to return to the previous mode.

You can also return to the previous mode by pressing the number 1 and 2 pedals simultaneously.

Practicing Along with CDs and MDs (AUX IN)

When playing CDs, MDs, tapes, or other such input, connect the CD or MD player, tape recorder, or other device to the AUX IN jack.

  • AUX IN is a stereo mini jack.

BOSS ME-50 - Practicing Along with CDs and MDs (AUX IN) - 1

Sound input to the AUX IN jack is mixed in the ME-50 with the guitar sounds, a convenient feature when using headphones for home practice and other such situations.

  • On the ME-50, you cannot adjust the volume level of the sound input from the AUX IN jack. Adjust this on the connected equipment.
  • Do not use a cable containing a resistor to connect CD or MD players to the AUX IN jack. If a cable incorporating resistance is used, audio from CD and MD players may become inaudible.
