Power Supply
Repairs and Data
301
452
• 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).
• Please be aware that all data contained in the unit’s
memory may be lost when the unit is sent for repairs.
Important data should always be backed up in another
MIDI device (e.g., a sequencer), or written down on paper
(when possible). During repairs, due care is taken to avoid
the loss of data. However, in certain cases (such as when
circuitry related to memory itself is out of order), we
regret that it may not be possible to restore the data, and
Roland assumes no liability concerning such loss of data.
302
• The AC adaptor will begin to generate heat after long
hours of consecutive use. This is normal, and is not a
cause for concern.
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.
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.
352a
• This device may interfere with radio and television
reception. Do not use this device in the vicinity of such
receivers.
352b
• 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.
354a
• 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.
355b
• 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
Additional Precautions
551
• 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 losing important data, we recommend that you
periodically save a backup copy of important data you
have stored in the unit’s memory in another MIDI device
(e.g., a sequencer).
552
• Unfortunately, it may be impossible to restore the contents
of data that was stored in another MIDI device (e.g., a
sequencer) once it has been lost. Roland Corporation
assumes no liability concerning such loss of data.
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.
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.
558a
• 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).
559a
• 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.
562
• 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.
401a
• 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.
402
• Never use benzine, thinners, alcohol or solvents of any
kind, to avoid the possibility of discoloration and/or
deformation.

Introduction
The GR-20 is a guitar synthesizer (guitar synth) which contains a high-quality sound generator and is
designed for easy operation.
The GR-20 carefully analyses the pitch and volume of each string as it tracks the signals being output by the
divided pickup (a pickup installed on your guitar which outputs a separate signal for each string), and uses
this information to trigger its built-in sound generator. At the same time, a data stream interpreting your
guitar performance can also be transmitted via the MIDI OUT connector, and used to play an external MIDI
device, such as a sound module.
Main Features
• You can play more than 450 different types of synth sounds in the same way as when playing your guitar
conventionally.
• In addition to playing the synth sounds by themselves, you can combine the normal guitar sound with the
synth sound.
• When applying an external effects unit to the normal guitar sound, you can use the Mix In jack to mix the
processed sound with the synth sound.
• The GR-20 can be used with any steel-string guitar on which a GK-3 or GK-2A (divided pickup; sold
separately) can be correctly installed.
• The GR-20 can also be used with a bass guitar on which a GK-3B or GK-2B (divided pickup for bass guitar;
sold separately) is installed.
• Built-in effects (reverb, delay, chorus) are provided for the synth sound, creating a rich and spacious
ambiance. (p. 20)
• You can adjust and store settings such as attack and decay time, and effect depth. (p. 20)
• You can use the GR-20's two foot pedals to apply a Hold effect or Glide effect. (p. 15)
• Use the built-in expression pedal to control parameters such as volume or filter. (p. 16)
• Since your guitar performance is output as MIDI data, you can use your guitar to play an external sound
module or as an input device for your MIDI sequencer. (p. 28)
• A guitar tuner is built-in for quick and accurate tuning. (p. 13)

Chapter 1 Play the Sounds!
Preparing Your Guitar
• In order to use the GR-20 you will need a guitar that has
a divided pickup (GK pickup) such as the Roland GK-3
or GK-2A, or a bass guitar that has a bass guitar divided
pickup such as the Roland GK-3B/GK-2B, which can
independently output a separate signal for each string.
Various guitar manufacturers sell GK-Compatible guitars
that have a pre-installed GK pickup or contain equivalent
functionality. For details, contact your guitar dealer or a
guitar manufacturer.
• For details on installing the GK pickup, refer to the
manual that came with your GK pickup.
• Notes may be sounded incorrectly if there are string
buzzes due to improper neck curvature or buzzing frets,
or if the octave adjustment (intonation) is incorrect.
In order to use the GR-20 with a bass guitar, follow the
procedure described in Chapter 6 Appendices “Switching
the GR-20 between bass guitar and guitar operation (p.
32)” to switch the GR-20 to bass guitar operation.

Turning the Power On
Once the connections have been completed, turn on power to
your various devices in the order specified. By turning on
devices in the wrong order, you risk causing malfunction
and/or damage to speakers and other devices.
Adjusting the Input
Sensitivity (GK SENS)
You’ll need to adjust the input sensitivity of each string
according to your picking strength and how the divided
pickup is installed.
1. If you've connected a device to MIX IN, turn on the
power of that device.
2. Turn on the power of the GR-20.
After you’ve turned on the power, you’ll be ready to play
when the panel indicators and the display reach the state
shown in the illustration. This state is called “Play mode.”
Before the GR-20 enters Play mode, it will indicate whether it
is currently in guitar mode or bass guitar mode.
• Guitar mode: “
• Bass guitar mode: “
If this adjustment is not made correctly, the system won’t
work properly. You must perform this adjustment to ensure
that you’re taking full advantage of the GR-20’s capabilities.
* Once you make this adjustment, it’s stored within the GR-20;
you won’t need to make it again. However, you should perform
the adjustment again after changing the strings or adjusting
the action of your guitar, or before using a different GK guitar.
* If you’re using a bass guitar, you can use the following table to
convert the string names and indications you see in the display
while performing the procedure below.

Switching between the Synth
Sound and Guitar Sound
Using the GR-20 with a
Multi-effects Unit
To switch between the synth sound and guitar sound, use the
selector switch provided on your GK pickup.
By connecting your multi-effects unit via MIDI, you can
automatically change sounds (patches) on the GR-20 by
selecting sounds (patches) on your multi-effects unit.
f
Channel (CH)
If the selector of your GK pickup (e.g., GK-3, GK-2A) is set to
the GK position (labeled SYNTH on the GK-2A), the synth
sound will be output. If set to the GUITAR position, the
guitar sound will be output. If the selector is set to MIX, both
sounds will be mixed and output.
* To adjust the volume balance between the synth sound and
guitar sound, use the volume (p. 20) of each patch to adjust the
synth sound, and the volume of the guitar or the connected
effects device to adjust the volume of the guitar sound.
MIDI uses “channels” to send independent streams of data
over a single cable. In order for data to be received, the
receiving device must be set to receive the channel that the
transmitting device is sending on. This means you must set
the transmit channel of your multi-effects unit to match the
receive channel of the GR-20.
1. Check the MIDI transmit channel of your multi-effects
unit.
For details, refer to the manual of your multi-effects unit.
2. Press the [SYSTEM EDIT] button a number of times until
the MIDI CH/PLAY FEEL indicator lights.
fig.2-03(MIDI CH)
3. Use the [NUMBER/VALUE] knob to change the setting.
Set the channel so it’s the same as the MIDI transmit
channel of your multi-effects unit.
4. Press the [EXIT] button.
The setting will be stored, and you will return to Play
mode.
* The decimal point in the display will blink while the setting is
being stored. Don't turn off the power during this time.
* If you turn off the power before returning to Play mode, the
setting you made will not be stored.

Chapter 2 Using the GR-20 with Guitar Effects
Patch Link Setup
(PATCH LINK SETUP)
Here’s how to link the patches (sounds) of your multi-effects
unit with the patches (sounds) of the GR-20. This will cause
the GR-20 to automatically switch to the specified sound
(patch) when you change patches on your multi-effects unit.
1. Use a MIDI cable to connect the MIDI OUT of your
multi-effects unit to the GR-20's MIDI IN.
2. Make sure that the MIDI transmit channel of your multieffects unit is the same as the MIDI channel of the GR-20
(p. 18).
3. Press the [SYSTEM EDIT] button a number of times until
the PATCH LINK SETUP/TRANSPOSE indicator lights.
fig.2-04(PATCH LINK)
4. On your multi-effects unit, select the patch for which you
want to specify a link.
* When you select a patch on your multi-effects unit, it will send
a “MIDI Program Change” message to the GR-20. The GR-20
will remember the content of this message, and will be ready
for you to specify the patch link setting.
* If two or more consecutive patch changes occur when you are
selecting a patch on your multi-effects unit, the GR-20 will
remember only the last-received MIDI program change.
5. Use the [BANK] knob and [NUMBER/VALUE] knob to
select the synth sound in the GR-20 that you want to use
with the effect you chose in step 4.
6. Repeat steps 4–5 to set as many links as you need.
7. Press the [EXIT] button.
You will return to Play mode, and the settings you made
will be stored.
* The decimal point in the display will blink while the setting is
being stored. Don't turn off the power during this time.
* If you turn off the power before returning to Play mode, your
settings will not be stored.

Chapter 3 Editing The Sounds
The GR-20 lets you modify the sound to your taste. This
process is called “editing.”
When you edit the settings, the decimal point in the display
will light, indicating that the sound has been modified from
the original settings.
Selecting a Sound to Start From
Use the [BANK] knob and [NUMBER/VALUE] knob to
select the sound (patch) from which you want to start editing
(p. 14).
Use the Knobs to Adjust the
Sound
fig.3-01(knob)
With the knob turned all the way to the left, it activates the
envelope follower function.
Envelope Follower (E FLW) function
The guitar synth analyzes the vibration of your guitar string
to detect the pitch, and then plays the appropriate synth
sound. This means that if the string vibration is less than a
certain level, it will not be possible to detect the pitch, and
the synth sound will be silenced at that point. For some
patches, the way in which the sound is silenced at this time
may produce an unnatural result.
The envelope follower function causes the volume of the
synth sound to always follow the string vibration of the
guitar, making the synth sound decay naturally along with
the decay of the string vibration.
* For some patches, the effect may be slight.
* Using the envelope follower function on a decay-type synth
sound such as piano or guitar may have the opposite effect,
producing an unnatural-sounding decay.
Adjusting the Spaciousness of the
Sound—CHORUS
* Immediately after a patch change, the sound you'll hear will
reflect the settings stored in the patch, regardless of the
positions of the knobs.
Adjusting the Attack—ATTACK
This adjusts the attack time of the sound. Turning the knob
toward the right will lengthen the time, producing a more
gradual attack. Turning the knob toward the left will shorten
the time, producing a sharper attack.
* You will hear the original sound when the knob is at the center
position.
* For some sounds, moving the knob may not make any
difference.
Adjusting the Release—RELEASE
This adjusts the release, from when you mute a string until it
decays to silence. Turning the knob toward the right will
lengthen the release, and turning it toward the left will
shorten the release.
* You will hear the original sound when the knob is at the center
position.
* For some sounds, moving the knob may not make any
difference.
20
This adjusts the depth of the chorus effect, which gives the
sound a spacious feel. Turning the knob toward the right will
deepen the effect, and turning it toward the left will lessen
the effect.
* You will hear the original sound when the knob is at the center
position.
* For some sounds, moving the knob may not make any
difference.
Adjusting the Reverberation
—DELAY/REVERB
This controls two types of reverberation effect.
Delay is an effect that produces echo-like effects, while
Reverb is an effect that simulates the way in which sound
reflects from the walls of a hall or tunnel. The left half of the
knob’s range applies a delay effect, and the right half applies
reverb. In either case, turning the knob farther will deepen
the effect.
Adjusting the Volume—LEVEL
This adjusts the volume of the patch.
* If you want to keep your edited sound, execute Write (p. 24) to
write your settings into a USER patch.
Chapter 3 Editing The Sounds
Editing Other Parameters
You will use the [PATCH EDIT] button and [NUMBER/
VALUE] knob to edit these parameters.
1. Press the [PATCH EDIT] button a number of times until
the indicator of the parameter you want to edit is lit.
Adjusting the Playing Feel
—PLAY FEEL
You can select the way in which the synth sound will
respond to your picking dynamics. You can more naturally
express your playing dynamics by changing this setting to
suit a particular playing style or sound.
2. Use the [NUMBER/VALUE] knob to edit the value.
1–4:
fig.3-02(Other Parameters)
The “1” setting gives you the widest range of
volume change in response to your picking
dynamics. With higher-numbered settings,
even softly picked notes will sound at a high
volume, making the volume more consistent
even when you use tapping techniques or if
your picking is not consistent.
No dynamics:
With this setting, notes will be sounded at a
fixed volume regardless of your picking
dynamics.
Adjusting the Brightness of the
Sound—FREQ
This controls the cutoff frequency of the filter within the
sound generator.
Increasing this setting will raise the frequency, producing a
brighter tone. Conversely, decreasing this setting will lower
the frequency, producing a softer tone.
Adding a Distinctive Character to
the Tone—RESO
Strum:
This setting suppresses softly picked notes.
Use this setting if unwanted notes are
triggered when you strum or when your finger
contacts a string unintentionally.
3. Press the [EXIT] button to return to Play mode.
* If you want to keep your edited sound, execute Write (p. 24) to
write your settings into a USER patch.
This controls the resonance of the filter within the sound
generator. Increasing this setting will produce a more
distinctive tone, while decreasing the setting will produce a
milder tone.
Adjusting the Pitch —TRANSPOSE
The pitch of the synth sound produced by the GR-20 can be
raised or lowered in one-octave steps relative to the pitch
you play on your guitar.

switch in conjunction with the pedals to perform the
following operations.
• When you press the DOWN/S1 switch, the GLIDE pedal
will function as Octave Down and the HOLD pedal will
function as Octave Up (TRANSPOSE).
When you press DOWN/S1 (or UP/S2) once again, the
pedals will revert to the patch up/down function.
• When you press the UP/S2 switch, the GLIDE pedal will
function as Glide and the HOLD pedal will function as
Hold.
When you press UP/S2 (or DOWN/S1) once again, the
pedals will revert to the patch up/down function.
Saving Patches and System
Parameter Settings on an
External Device (BULK DUMP)
Here’s how you can save the user bank patches and the
system parameter settings via MIDI on an external device or
computer (sequencer).
You can also transfer data via a MIDI cable directly between
two GR-20 units.
Sending GR-20 data in this way is called “bulk dump,” and
receiving this data is called “bulk load.”
1. Press the [SYSTEM EDIT] button enough times to get the
SW MODE indicator to light.
What are System Parameters?
Parameters that apply to the entire GR-20 (such as SW
MODE and MIDI CH) are called “system parameters.”
1. Connect the GR-20’s MIDI OUT to your external device’s
MIDI IN.

Here’s how GR-20 settings saved via Bulk Dump on an
external device can be loaded back into the GR-20 via MIDI.
Performing the BULK LOAD operation will rewrite all the
data in the GR-20. Be aware that all currently existing data
will be lost.
1. Connect your external device’s MIDI OUT to the GR-20’s
MIDI IN.
3. Begin recording on the external device that will receive
the data.
If you want to transfer data between two GR-20 units,
put the receiving GR-20 in the Bulk Load (p. 27) Ready
state.
4. Press the [WRITE] button.
2. Turn off the power of the GR-20, and then hold down the
[PATCH EDIT] button and turn the power back on again.
The display will indicate “dP.”
3. Using the [NUMBER/VALUE] knob, get “Ld” to appear
in the display.

Chapter 5 Connecting an External Sound
Module or Sequencer
You can use the GR-20 to play an external sound module via
MIDI, or use it as an input tool for your sequencer.
Connecting an External
Sound Module or Sequencer
Connect the GR-20 to your external sound module or
computer (sequencer) as shown in the diagram.
fig.5-01(External Sound Module)
MIDI IN
Setting the Transmission Mode
The GR-20 lets you select either “Mono Mode transmission”
or “Poly Mode transmission” as the method it uses when
transmitting MIDI messages.
❍Mono Mode transmission
Performance data for each string will be transmitted individually,
with each using its own separate MIDI channel. Starting with the
selected MIDI CH, six consecutive MIDI channels will be selected
automatically. For example, if MIDI CH is set to 3, the six channels
3–8 will transmit MIDI data for strings 1–6, respectively.
Since continuous pitch change data (MIDI Pitch Bend messages)
can be transmitted independently for each string, this allows you
to use performance techniques typical of a guitar, such as use of
the whammy bar and string bending.
* The connected sound module must be a multitimbral sound
module with at least six parts.
MIDI IN
❍Poly Mode transmission
MIDI OUT
Performance data for all strings will be transmitted on a single
MIDI channel. The selected MIDI CH will be used. Since the
entire guitar will use only one channel, this lets you conserve
MIDI channels. This also lets you control a sound module that
is not able to receive six channels simultaneously.
* However, if two or more strings are sounding, bend data will
not be transmitted; pitch change will occur only in semitone
steps. This means that the pitch actually being played by the
guitar will not be completely reflected by the synth sound.
fig.5-02(External Sequencer)

3. Press the [EXIT] button.
The setting will be stored, and you will return to Play
mode.
* The decimal point in the display will blink while the setting is
being stored. Don't turn off the power during this time.
* If you turn off the power before returning to Play mode, the
setting you made will not be stored.
Setting the MIDI Channel
(BASIC CHANNEL)
* You can select only channels 1–11. Channels 12–16 are not
available.
* If the output mode is set to “Mono Mode,” the GR-20 will use
six channels starting with the channel you specify here.
1. Press the [SYSTEM EDIT] button a number of times until
the MIDI CH/PLAY FEEL indicator lights.
fig.2-03(MIDI CH)
MIDI Messages Transmitted by
the GR-20
As performance data, the GR-20 transmits a note-on message
when you play a note, a note-off message when a note stops,
and pitch bend messages when you bend a note.
In addition to these messages, the GR-20 also transmits the
following MIDI messages so that your performance can be
faithfully reproduced when recorded and played back by a
sequencer.
❍ENVELOPE FOLLOW
If the RELEASE setting is E FLW (p. 20), MIDI control change
number 18 (general purpose controller 3) will be transmitted
according to the amplitude of the guitar string’s vibration.
❍GLIDE pedal
MIDI pitch bend messages will be transmitted according to
the change in pitch.
❍HOLD pedal
If the HOLD MODE is H1, H2, or H3
Outputting of MIDI note-off messages will be suspended as
long as you continue pressing the pedal.
If the HOLD MODE is H4
Control change number 64 will be transmitted.
2. Use the [NUMBER/VALUE] knob to change the setting.
Set the channel so it’s the same as the MIDI transmit
channel of your multi-effects unit.
3. Press the [EXIT] button.
The setting will be stored, and you will return to Play
mode.
* The decimal point in the display will blink while the setting is
being stored. Don't turn off the power during this time.
* If you turn off the power before returning to Play mode, the
setting you made will not be stored.
Specifying the Bend Range
* In the case of Poly Mode transmission (p. 28), the Hold effect
cannot be conveyed entirely because it cannot be processed
independently for identical pitches played on different strings.
❍Expression pedal
Control change number 7 (Volume) or number 4 (Foot Type)
is transmitted according to movements of the pedal.
❍Program change
This message is transmitted when you switch patches.
The sound bank is transmitted by MIDI Bank Select (CC#0),
and the sound number is transmitted as a Program Change
(PC).
Since the GR-20 transmits Pitch Bend data based on a bend
range of 24, you must set your sound module to a bend range
of ±24. For details on making this setting, refer to the manual
for your sound module.
29
Chapter 5 Connecting an External Sound Module or Sequencer
Local Control Off
* To turn Local Control on, turn the power of the GR-20 off,
then on again.
The state in which the GR-20’s guitar control section is
internally connected to the sound generator is referred to as
“Local Control On.” In contrast, the Local Control Off setting
internally disconnects the GR-20’s sound generator from the
guitar control section, so that the sound generator will produce
sound only in response to MIDI messages from MIDI IN. The
guitar performance will be transmitted only from MIDI OUT.

you can avoid conflicts from occurring between the
performance data from your guitar and from the sequencer.
1. Turn off the GR-20, and then hold down the [SYSTEM
EDIT] button while turning the power on again.
The display will indicate “Lo” for approximately one
second, and the GR-20 will then enter Play mode.
fig.5-04(Local Off)
* The Local Control Off setting cannot be stored.
* If the connections between the GR-20 and your external MIDI
device form a loop, you must use the Local Control Off setting.
If you make connections with this setting On, switches will
not function, and the system will not operate correctly.

Chapter 6 Appendices
Restoring the Factory
Settings (Factory Reset)
If you want, you can get back all the settings and patches that
the GR-20 had when you first took it out of the box; this
process is called “Factory Reset.”
You can restore the entire GR-20 to the factory-set state, or
restore an individual user patch to its factory-set state.
—
: Only the specified patch will be returned to the factory
settings.
3. Press the [WRITE] button.
The decimal point in the display will blink, the Factory
Reset operation will be executed. Then you will return to
Play mode.
* Do not turn off the power while the decimal point is blinking.
Calibration settings for the expression pedal (p. 31) will not
be returned to the factory-set condition. This means that even
if you execute Factory Reset, you don't need to calibrate the
expression pedal again.
When you execute Factory Reset, all data you currently have
stored in the unit will be overwritten by the factory-default
data. If the GR-20 contains important data that you want to
keep, use Bulk Dump (p. 26) to save it on an external MIDI
device before you execute a Factory Reset.
1. Turn off the GR-20, and then hold down the [WRITE]
button while turning the power on again.
fig.6-01(FACTORY RESET 1Åj
Calibrating the Expression
Pedal
When the GR-20 is shipped from the factory, the expression
pedal is calibrated for optimum performance. However, with
extended use, or depending on the conditions of use, this
calibration may drift. If you experience problems, such as
being unable to use the volume pedal to silence the sound
entirely, or if the pitch does not rise or fall through the full
range specified, you can use the following procedure to recalibrate the expression pedal.
1. Turn off the power of the GR-20. Then hold down [EXP
PEDAL] while you turn the power on again.
The display will indicate “Pu.”
2. Fully release the pedal (applying pressure at the heel),
and press the [WRITE] button.
The display will indicate “Pd.”
3. Depress the pedal completely (applying pressure at the
toe), and press the [WRITE] button.
2. Use the [NUMBER/VALUE] knob to select the range of
data that you want to restore to the factory settings.
The setting will be stored, and you will return to Play
mode.
* The decimal point in the display will blink while the setting is
being stored. Don't turn off the power during this time.
* If you turn off the power before returning to Play mode, the
setting you made will not be stored.
: The entire GR-20 will be returned to the factory
settings.
When you perform this operation, the guitar/bass
setting will return to guitar mode (the default setting).
If you want to use the GR-20 with a bass guitar, you’ll
need to follow the procedure described in “Switching
the GR-20 between bass guitar and guitar operation
(p. 32)” to switch the GR-20 back to bass guitar mode.
31
Chapter 6 Appendices
Regarding GR-20 bass guitar support
The GR-20 you purchased includes system program version 2, which allows the bass guitar range to be supported as well.
By connecting a bass guitar that has a separately sold GK-2B or GK-3B divided pickup (for bass) installed, you can play
the GR-20 from your bass guitar.
When shipped from the factory, the GR-20 is set for use with a guitar. The procedure described below lets you switch the GR-20 between
guitar and bass operation.
* You may repeat this procedure as many times as you like. Furthermore, this procedure will not affect the user patch data.
Switching the GR-20 between bass guitar and guitar operation ..........
1. Switch off the GR-20. Then while holding down the [GK SENS] button, turn on the power.
Shortly afterwards, the display will indicate “
” or “
.”
2. Use the [NUMBER/VALUE] knob to select bass guitar or guitar operation.
• Bass guitar operation:
Turn the [NUMBER/VALUE] knob toward the right (clockwise) to make the display read “
.”
• Guitar operation:
Turn the [NUMBER/VALUE] knob toward the left (counterclockwise) to make the display read “
.”
3. Press the [EXIT] button.
The setting will be stored, and you will be in Play mode.
* The decimal point of the display will blink while the setting is being stored. Do not switch off the GR-20’s power while this takes place.
* Please note that the setting will not be stored if you neglect to return to Play mode before you switch off the unit.
* The setting is preserved until you repeat this procedure again.
How the Bass Guitar and Guitar settings differ ...................................
• The range of pitches produced by the GR-20 is switched between guitar and bass guitar ranges.
• In some of the preset patches, this setting causes the actual pitch produced by the synthesizer to be one or more octaves above or
below the pitch that is input. The same applies to user patches that you create based on these preset patches.
(Example) BANK= BASS/GTR No= “Wood Bass”
Bass Guitar operation
The synthesizer will sound at the same pitch as the input.
Guitar operation
The synthesizer will sound one octave lower than the input.
• When setting the input sensitivity (GK SENS), the numbers shown in the left of the display correspond to strings as shown in the
diagram below.
You must install the GK-2B/3B pickup on your bass guitar as shown below. The system will not operate correctly if you install
the pickup any other way.

Due to the laws of physics, lower pitches take more time
to analyze. This means that with a bass guitar, and its
inherently lower pitches, you should expect that it may
take longer for the synth sound to begin.
The effect produced using the expression pedal is
different for each sound (patch).

In order to convey the beginning of a note as quickly as
possible, and to allow the pitch to change flexibly, the
GR-20 transmits the pitch as a combination of note
messages and pitch bend messages. This means that
when you view only the note data using the event list
(“microscope”) screen of your sequencer, the data may
appear to be different than the pitch that is actually
sounded.

●Request Data1 RQ1 (11H)
THis message is to request the GR-20 to transmit its parameters.
The address and size indicate the type and amount of parameters requested.
The GR-20 itself does not send this message.
When the GR-20 receives this message, it responds with appropriate parameters if the
following conditions are satisfied:
1. The address indicated with RQ1 matches with one of the parameter base address of the
GR-20
2. When the Bulk Load standby mode.
With these conditions provided, the GR-20 transmits specified parameters in Data Set 1
(DT1) message.

1. Exclusive status is F0H.
2. Roland’s Manufacturer ID is 41H.
3. This is the device ID.(Fixed at 10H for GR-20)
4. Model ID of the GR-20 is 00H 72H.
5. DT1 (Data Set1) Command ID is 12H.
6. These are the parameter addresses. Please find the start address of the USER BANK 01
Patch from the table of the start address.You can find the address as 01H 00H 00H 00H.
Next, please find the offset address of the LEVEL Parameter from the table 4-2. That is
00H 00H 06H.The result will be 01H 00H 00H 06H.

(the offset address of the LEVEL)
7. The settings value for LEVEL is 90. This is expressed as 5AH in hexadecimal notation
with two digits. (Refer to the attached Chart A-1)
The settings value for FREQ is 115. This is expressed as 32H in hexadecimal notation with
two digits.
The settings value for RESO is 60. This is expressed as 3CH in hexadecimal notation with
two digits.
The settings value for TRANSPOSE is +1oct. This is expressed as 03H in hexadecimal
notation with two digits from Table 4-4.
8. This is the check sum byte.The error checking process uses a Checksum and provides a
pattern where the last significant 7 bits are zero when values for address, data(or size)
and the Checksum are summed.
If the address of the exclusive message that you wish to send is aa bb cc ddH and the
data(or size) is ee ff hh iiH,
aa + bb + cc + dd + ee + ff + hh + ii = sum
sum / 128 = quotient ...remainder
128 - remainder = checksum
* However, when sum=0, then the checksum also results in 0.
The GR-20 transmits this message in the following conditions.
When data request (RQ1) is received with the Bulk Load mode, and the specified
parameters are transmitted.
or you executes Bulk Dump function.
In case of this example,
Regarding details of the parameter transmitted/received, please refer to the Parameter
Address Map.
Using the above formula, Checksum will be as follows.

/Example of creating the exclusive message/
If you want to set as the following the parameter LEVEL/FREQ/RESO TRANSPOSE of
USER BANK 01 Patch, create data as the following and send it to your GR-20.

= 210 (sum)
210 (sum) / 128 = 1 (quotient) ...82 (remainder)
checksum = 128 - 82 (remainder) = 46 = 2EH
If you calculate with hexadecimal,
aa + bb + cc + dd + ee + ff = sum (xxH)
sum (xxH) / 80H = quotient ...remainder
80H - remainder = checksum
Checksum will be as follows.
01H + 00H + 00H + 06H + 5AH + 32H + 3CH + 03H = D2H
D2H / 80H = 01H (quotient) ...52H (remainder)
checksum = 80H - 52H (remainder) = 2EH
9. F7H is the mark of the end of exclusive.
