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

Power Supply

• 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.
• 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.
• 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.

Preparations to Make Before Performing

Although the GI-20 can be used with both guitars and basses, the descriptions here are based on the assumption you are using a guitar or six-string bass, and the numerals indicating the "strings" in the descriptions of settings and procedures correspond to the 1st through 6th strings of a guitar or regular six-string bass. If you are using a four-string or five-string bass, substitute the following numbers for those discussed in the manual.

1st String	→	---
2nd String	→	1st String (G)
3rd String	→	2nd String (D)
4th String	→	3rd String (A)
5th String	→	4th String (E)
6th String	→	5th String (B)

Items to Have On Hand

• To use the GI-20, you need a guitar or bass equipped with a pickup capable of separately outputting the signals for each individual string (a divided pickup).
  ● The GI-20 contains no internal sound generator, so you will need to use a separate MIDI sound module.
  ● Determine which other gear you will need by referring to the connection examples (p. 10).

Installing the Divided Pickup on the Guitar or Bass

First, attach the divided pickup to your instrument. Refer to the GK series Owner's Manual for instructions on installing the pickup.

Guitars That Cannot Be Used with the GK Series Pickup

While the compact design of the GK series pickup allows its installation on many different guitars, please note the following types of guitars on which it cannot be used:

• 12-string, pedal steel, and other specially strung guitars.
- Nylon-strung, gut-strung, and similar guitars; bass guitars.
- Guitars which, due to their physical design, lack the space for proper mounting of the GK series pickup.

MEMO

Several guitar manufacturers produce guitars that can be connected directly to the GR series with a GK cable, without the use of a GK series pickup. For more information, please ask your dealer or these guitar manufacturers.

About MIDI

MIDI stands for “Musical Instrument Digital Interface,” a worldwide standard that enables electronic instruments and peripherals to share information about performances, sound switching, and other functions. MIDI is a standard that is shared by a wide range of instruments from different manufacturers. For instance, you could use a MIDI controller from company A to play a sound module from company B or send data to a sequencer from company C.

MIDI Messages Handled by the GI-20

What follows is a list of some of the different types of MIDI messages that the GI-20 can handle.

• “Note On messages” provide information on what string was played, and its pitch and force.
• “Note Off messages” provide information on when a string stops vibrating.
• “Bend messages” provide information for changing the pitch smoothly, such as when bending, vibrato, or hammering.
• “Bank Select messages” and “Program Change messages” transmit commands for switching patches.
• “Control Change messages” provide information on changes in volume and effects.
• “System Exclusive (SysEx) messages” provide information for exchanging patch data with external instruments.

Connection Examples

When the guitar or bass is set up, connect the various devices as shown in the connection examples given in the figure.

* The GI-20 connects to sound modules only via MIDI, not USB, even if the sound module is USB equipped.

Selecting the Guitar or Bass

Set the GUITAR/BASS switch on the rear panel to match the instrument you are playing, in accordance with the range in which you are playing. Switch to GUITAR if you are using a guitar; if using a bass, switch this to BASS.

* Note that the GI-20 may not operate properly if this setting is not correct.

After the power is turned on, "Gt" (guitar) or "bG" (bass) flashes in the display for several seconds, allowing you to check the status of the GUITAR/BASS switch.

* This does not appear in the display when the GUITAR/BASS switch setting is changed at a later point.

GUITAR

BASS

* With the factory settings, all of the GI-20's patch settings are optimized for guitar. If you are using a bass, you can carry out a Factory Reset (p. 34), and change the settings so that they are suitable for the bass.

Chapter 1 Try Playing Some Sounds

Playing Sounds from a Sound Module

This section explains how to connect the GI-20 to an external MIDI sound module and use it as a guitar synthesizer.

Connect the GI-20 and the external MIDI sound module as shown in the connection example in the figure.

Turning On the Power

Once your connections have been completed, turn on power to your various devices in the order specified. By turning on the devices in the wrong order, you risk causing malfunction and/or damage to speakers and other devices.

1. MIDI Sound Module

2. GI-20

* This unit is equipped with a protection circuit. A brief interval (a few seconds) after power up is required before the unit will operate normally.

1. Monitor Speakers

Turning Off the Power

1. Turn the volume down all the way on the MIDI sound module and monitor speakers or other device.
2. Turn off the power to the power amp or other device.
3. Turn off the power to the MIDI sound module and the GI-20.

Adjusting the Input Sensitivity (SENSITIVITY)

For best performance, it is important to adjust the input sensitivity for each individual string.

* You can store up to four sets of sensitivity settings (G1–G4), which means there is no need to readjust the settings from scratch each time you switch guitars and basses.

1. Turn the PARAMETER knob to "GUITAR SEL."

1. Press [PATCH/VALUE] to select the save destination for the sensitivity settings (G1–G4).

When G1 is selected

1. Press [SELECT] to switch to the Sensitivity settings screen.

The left numeral indicates the string number, and the right numeral indicates the value of the sensitivity setting.

The level is indicated by the five indicators at the top of the display.

1. Play each string individually with the maximum force to be used during the actual performance, and as you play the string, adjust the sensitivity with [PATCH/VALUE] until all five indicators light up momentarily.

1. When you have finished making the settings, turn the PARAMETER to return to "PLAY MODE."

* Sensitivity is a system parameter. The settings are saved automatically when the memories (G1–G4) is changed or the PARAMETER knob is turned, even without the Write procedure being carried out. The settings in each of the memories (G1–G4) are applied to all patches. However, whichever of the sets G1–G4 to be used by each patch (Calling Up Input Sensitivity Settings" p. 18) is a patch parameter. Use the Write procedure to save these settings.

Selecting Patches

Switching the GI-20's patches allows you to change the values of settings instantly and perform using a wide variety of sounds.

What is a Patch?

The various information used in performing with the GI-20 is stored in sets called “patches.” In each patch you can store the settings values for the parameters described below, and switching these patches allows you to reproduce their settings instantly.

System Parameters and Patch Parameters

In contrast to the “patch parameters,” whose settings can be stored to each patch individually, parameters that are used by the GI-20 overall are called “system parameters.”

The following describes the different types of patch parameters and system parameters.

* Patch parameters are indicated in blue on the front panel.

System Parameters

• SENSITIVITY (p. 11)
• MIDI BASIC CH (p. 14)
• MIDI CTL CH (p. 15)
  • PC MASK (p. 29)
• MASTER TUNE (p. 28)

System parameters are stored in the GI-20 when you turn the PARAMETER knob after making changes to the settings.

* The MIDI BASIC CH and MIDI CTL CH parameters are also stored in the GI-20 when you press [SELECT] after making changes to the settings.

• MIDI PLAYBACK (p. 17)
• BEND DATA THIN (p. 31)
- RECEIVE CONTROL CHANGE DATA THIN (p. 32)
• BEND RANGE MAX (p. 32)
• USB DRIVER TYPE (p. 33)

These parameters are saved to the GI-20 the moment you change the settings values.

Patch Parameters

• GUITAR SEL (p. 18)
- PLAY FEEL (p. 18)
- ASSIGN (p. 19)
• PRG CHANGE (p. 25)
• BEND RANGE (p. 23)
• TRANSPOSE (p. 23)
• STRING MUTE (p. 26)
• MONO/POLY (p. 14)

With patch parameters, the Write procedure (p. 26) is used to save the settings values to individual patches after changes are made to the settings.

How to Switch Patches

Switch patches by pressing [PATCH/VALUE] in "Play mode" (p. 16).

● Each time you press [PATCH/VALUE ▲], the patch numbers are switched one at a time in ascending order, from 01 on up to 50.
● Each time you press [PATCH/VALUE ▼], the patch numbers are switched one at a time in descending order, from 50 down to 01.

When Not Switching Patches

With the GI-20, patches can only be switched in Play mode. When switching patches, turn the PARAMETER knob to return to Play mode.

Each of the GI-20's patches at the time the GI-20 is initially purchased is set for compatibility with GM sound modules.

Setting the sound module to GM mode when using a GM-compatible sound module allows you to enjoy a variety of sounds with the GI-20, just as at the time it was purchased.

MEMO

GM (General MIDI) is a set of recommended standards covering the way sounds are played by MIDI sound module, the arrangement of internal sound lists, and other aspects involving production of sound with sound generators. GM-compatible MIDI sound generating devices are called GM sound modules, and these devices are capable of reproducing essentially the same musical performance, regardless of the manufacturer or type of device.

Setting the Transmission Mode (MONO/POLY)

The GI-20 features two kinds of modes to transmit MIDI messages.

    F["5th"] --> B
    G["6th"] --> B
    H["String"] --> B
    B --> I["Sound Module"]

* With the factory settings, all patches are set to MONO MODE.

MONO (MONO MODE)

In this mode, each individual string uses a separate channel, thus totaling six channels.

Since each string uses a different MIDI channel, you can select different sounds for each string and continuously change the pitch data when using string bending and other special techniques with specific strings. However, this requires a multitimbral sound module.

POLY (POLY MODE)

In this mode, the information for all six strings is transmitted over a single channel.

Since the MIDI messages for all six strings are transmitted over a single channel, it simplifies the settings for the sound module and reduces the number of MIDI channels used. However, options are more limited, for example, the same sound must be selected for all of the strings.

* In POLY mode, the Pitch Bend/Glide and Vibrato set in Assign (p. 19) function as follows.

When chords are played, Pitch Bend and Glide change in semitone steps and Vibrato does not function. These function normally when you play notes individually.

1. Turn the PARAMETER knob to "MIDI CHANNEL."

1. Press [SELECT] to select MONO/POLY.

When MONO/POLY is selected, only the leftmost indicator lights up.

1. Press [PATCH/VALUE] to select either MONO or POLY.

1. To save the setting, carry out the Write procedure (p. 26).

* If you do not want to save the setting, turn the PARAMETER knob to return to "PLAY MODE."

1. When you have finished making the settings, turn the PARAMETER knob to return to "PLAY MODE."

Setting the MIDI Transmit Channel (BASIC CH)

This sets the GI-20's MIDI Transmit channel (here called the "basic channel"). Set the MIDI channels as shown below according to whether the GI-20 is in POLY or MONO MODE.

When in POLY MODE

The performance data for all of the strings is transmitted over the Basic channel.

When in MONO MODE

1st String: Transmitted over the Basic channel.

2nd String: Transmitted over the Basic channel + 1.

3rd String: Transmitted over the Basic channel + 2.

:

6th String: Transmitted over the Basic channel + 5.

* With the factory settings, all patches are set to MONO MODE, and the Basic channel is set to Channel 1.

1. Turn the PARAMETER knob to "MIDI CHANNEL."

2. Press [SELECT] to select BASIC CHANNEL (BASIC CH).

When BASIC CHANNEL is selected, the two indicators at the left light up.

3. Press [PATCH/VALUE] to select the Basic channel number.

* Since the six channels used in MONO MODE are consecutive, selecting Channel 12–16 as the Basic channel results in the MIDI channel number for the sixth string to exceed the allowable range of 1–16. In this case, the display flashes, and the performance data is sent by Channel 11–16.

4. When you have finished making the settings, turn the PARAMETER knob to return to "PLAY MODE."

* The Basic channel is a system parameter. It is saved automatically when the PARAMETER knob is turned, even without the Write procedure being carried out, and the settings values are applied to all patches.

Setting the Control Channel (CTL CH)

You can connect a foot controller or other such device to the MIDI IN connector to switch patches and perform other operations. In this case, you will need to set the “control channel” for reception of MIDI messages.

The control channel is a dedicated channel used only for receiving MIDI messages transmitted over the channel set to the same number. MIDI messages transmitted over other channels are disregarded.

* However, when the control channel is set to "OMNI mode" (Omni), MIDI messages are received regardless of the channel.
* With the factory settings, the control channel is set to "OMNI."

The GI-20's MIDI IN/OUT cannot be used under the following conditions.

• When MIDI IN and OUT are connected directly
• When the Soft Thru for the sequencer connected to MIDI IN/OUT is set to ON

In either case, the error message "E3" (p. 37) appears, and the GI-20 stops functioning normally.

The GI-20 can receive the following types of MIDI messages over the control channel.

Control Change

Control Change messages received over the control channel are transmitted over the basic channel (in MONO mode, all of the transmission channels for the strings).

Additionally, you can control the functions set in Assign (p.19) by assigning Control Changes to the general (assignable) controllers 3–8.

General Purpose Controller 3 (CC #18): Expression Pedal

General Purpose Controller 4 (CC #19): Foot Switch 1

General Purpose Controller 5 (CC #80): Foot Switch 2

General Purpose Controller 6 (CC #81): GK Volume

General Purpose Controller 7 (CC #82): S1 Switch

General Purpose Controller 8 (CC #83): S2 Switch

* These Control Change messages are not transmitted externally to other devices.
* For data corresponding to the Foot Switches 1/2 and S1/S2 Switches, 00h–3Fh are output as 00h (OFF), and 40h–7fh are output as 7fh (ON).

Chapter 1 Try Playing Some Sounds

Program Change

These messages switch the GI-20's patches.

Program Changes 0–49 correspond to Patches 1–50 on the GI-20.

* Program Changes 50–127 are disregarded.

Performing on the Guitar

When you have finished making the settings, try playing the guitar or bass to play sounds from the MIDI sound module.

1. Turn the PARAMETER knob to "PLAY MODE."
2. Play the guitar or bass.

Connecting to a Computer

This section explains how to connect the GI-20 to your computer with a USB cable and use it as a tool to input data to sequencers and other devices.

No USB cable is included with the GI-20. You will need to purchase a third-party USB cable separately.

Do not press [SELECT] or connect (or disconnect) any device or cable to (or from) the USB connector during performances or while operating sequencers or other devices with the computer. This may cause malfunctioning of the computer or MIDI sound module.

* First, follow the instructions in "Installing & Setup the Driver" (p. 45) to install the GI-20 driver on your computer.

Setting the MIDI Port

This setting determines which MIDI data from the GI-20 is used by the applications on your computer.

In the application's MIDI device selection screen, select "Roland GI-20 MIDI IN" as the input device and "Roland GI-20 MIDI OUT" as the output device.

* For instructions on selecting the input device, refer to the owner's manual for the application you are using.

Roland GI-20 MIDI IN

This is the port used for inputting performance data to the GI-20 from your computer.

Input here is performance data from guitars and basses equipped with GK connectors.

Roland GI-20 MIDI OUT

This is the port used for outputting performance data to your computer from the GI-20.

When MIDI PLAYBACK is set to ON, the performance data the GI-20 receives from the computer is output as is from the GI-20's MIDI OUT connector (refer to "Setting the MIDI Data Path (MIDI PLAYBACK)" p. 17).

Setting the MIDI Data Path (MIDI PLAYBACK)

You can switch the MIDI messages that are output from MIDI OUT. Set MIDI PLAYBACK to "Off" when you want to output performance data input from the GK input directly from the MIDI OUT connector. When you want to output your computer's MIDI performance data from the GI-20's MIDI OUT connector, for example, if you want to play the computer's MIDI data through an external MIDI sound module, set this to "On."

1. Turn the PARAMETER knob to "PLAY MODE."

1. Press [SELECT] to set MIDI PLAYBACK to "On" or "Off." [SELECT] is lit when this is set to "On"; when set to "Off," [SELECT] is unlit.

* MIDI PLAYBACK cannot be set to "On" unless the computer and the GI-20 are connected with a USB cable.

Chapter 2 Creating Your Own Settings (Patches)

Calling Up the Input Sensitivity Settings

Select input sensitivity settings appropriate for the guitar or bass you are using.

1. Turn the PARAMETER knob to "GUITAR SEL."

2. Press [PATCH/VALUE] to select a setting from G1 to G4.

You can make the input sensitivity settings for each of the sets G1–G4 (p. 11).

When G1 is selected

3. If you want to save the settings, carry out the Write procedure (p. 26).

* If you do not want to save the settings, turn the PARAMETER knob to return to "PLAY MODE."

4. When you have finished making the settings, turn the PARAMETER knob to return to "PLAY MODE."

Setting the Feeling of the Performance (PLAY FEEL)

With guitars, in contrast to keyboards and similar instruments, the vibrating strings are touched directly, giving the player the ability to exert subtle control over the dynamics. To realize most faithfully this aspect of the guitar, you need to set a “performance response” for each patch that is appropriate both for the way the instrument is being played, as well as the sounds that are used.

These parameters are controlled by "PLAY FEEL." For example, you can get more natural dynamic expression by changing PLAY FEEL according to whether you are playing the strings with your fingers or using a pick.

1. Turn the PARAMETER knob to "PLAY FEEL."

2. Press [PATCH/VALUE] to change the value.

3. If you want to save the settings, carry out the Write procedure (p. 26).

* If you do not want to save the settings, turn the PARAMETER knob to return to "PLAY MODE."

4. When you have finished making the settings, turn the PARAMETER knob to return to "PLAY MODE."

The PLAY FEEL settings and their effects

nr: Normal

General picking, thus the standard setting for play.

Fi: Finger picking

The setting for when you want to perform with the feeling finger picking provides. Sensitivity is a little higher than Normal.

Hd: Hard picking

This setting is for those who pick rather hard, and the sensitivity is a little lower than Normal.

* When there is a problem with the guitar's arrangement, and the only places GK series pickup can be installed are too close to the strings, you may be able to improve the behavior with the settings in each patch.

SF: Soft picking

For picking that is a little weaker. Sensitivity is a little higher than Normal.

tP:Tapping play

When making use of many kinds of picking techniques, such as tapping play (or “right-hand play”), pulling-off, or hammering-on, this setting provides very stable sound expression. The range of power that can be expressed is a bit narrow.

nd: No dynamics

With this setting, no matter how hard or softly you play, you get uniform volume and tone. Use this setting with tones like Synth Lead or Organ when you want to transmit a feeling without expression.

Setting the Pedal and Switch Functions (ASSIGN)

You can assign various functions to an expression pedal (the optional EV-5) or foot switch (the optional FS-5U) connected to the GI-20, or to the GK series pickup's S1, S2, and GK VOL.

* When connecting a foot switch (the optional BOSS FS-5U) to the FOOT SW jack, you can use the optional PCS-31 connection cable to connect two foot switches. Only FOOT SWITCH 1 is operational when just one FS-5U is connected to the FOOT SW jack.

Functions That Can Be Selected With ASSIGN

The following describes the functions that can be assigned to the controllers.

Controller	function
Expression Pedal	CC#1-31, 64-95, Pitch Bend 1-6, Vibrato 1-4
Foot Switch 1/2	CC#1-31, 64-95, Patch Up, Patch Down, Octave Up, Octave Down, GR Hold1-3, Glide Up 1-8, Glide Down 1-8, Vibrato 1-4
GK Volume	CC#1-31, 64-95
S1/S2 Switch	Patch Up/Down, Octave Up/Down

* When “POLY” is selected as the transmission mode, the Pitch Bend/Glide and Vibrato function as follows.

When BEND RANGE (p. 23) is set to anything other than Chromatic, Pitch Bend/Glide changes in semitone steps when chords are played, and Vibrato does not function. These function normally when you play notes individually.

When patches are switched, no signal is transmitted to restore the Control Change value transmitted with the previous patch. Therefore, if the same assign settings are used for both of the patches prior to and following the switch, the status of the controllers is carried over. However, if the assign settings are different for the patch you are switching to, you cannot restore the value for the Control Change transmitted with the earlier patch, so you will need to be aware of the following.

(Example)

The volume of a patch with CC 7 (Volume) assigned to the expression pedal is lowered to the minimum level. After this, if you switch to a patch with a different assign setting, since CC 7 (Volume) is not controlled in that patch, no sound is output, even when you press the expression pedal.

1–31, 64–95 (MIDI Control Change CC#1–31, CC#64–95)

(Ex.) CC 1

Transmits Control Change messages (#1–#31, #64–#95) from MIDI OUT. For more on the functions controlled with Control Change messages, refer to the “MIDI Implementation” (p. 40) and owner’s manual for the sound module you are using.

Pu: Patch Up

The patch number increases each time the switch is pressed.

Chapter 2 Creating Your Own Settings (Patches)

Pd: Patch Down

The patch number decreases each time the switch is pressed.

Pt: Patch Up/Down

The S1 switch is used for the Patch Down function and the S2 switch for the Patch Up function.

ou: Octave Up

All notes are raised an octave each time the switch is pressed. The pitches can be raised up to a maximum of two octaves.

* The pitches of notes currently being played are not altered.

od: Octave Down

All notes are lowered an octave each time the switch is pressed. The pitches can be lowered by a maximum of three octaves.

* The pitches of notes currently being played are not altered.

oC: Octave Up/Down

The S1 switch is used for the Octave Down function and the S2 switch for the Octave Up function.

* If notes transposed using the Octave Up/Down function are in registers that are unplayable with MIDI messages, the MIDI messages in the expressable range above or below that octave are transmitted.

H1: GR Hold 1

The sound being played are held while the foot switch is pressed.

By holding down the pedal, you can have the synth sound play without stopping, even as you change the position (the point at which the stringed is pressed against the guitar neck) or play discontinuous notes.

However, you cannot play two different sounds from the same string simultaneously.

H2: GR Hold 2

The sound being played is held the moment you press the foot switch, and continues to be held while you hold the pedal down.

The synth sound is not played during the hold, allowing you to hold chords played with the synth sound while you play the melody using the normal guitar sound.

H3: GR Hold 3

The sound being played is held the moment you press the foot switch, and continues to be held while you hold the pedal down.

Since you can still play the strings that aren't being held, it means you can hold chords played with the fifth and sixth strings using the synth sound, while you play the melody with the first through fourth strings, also using the synth sound.

* If the hold function is assigned to two foot switches, and both switches are pressed, the hold function for the foot switch pressed first takes priority, and the hold function for the foot switch pressed afterwards does not have any effect.

u1: Glide Up 1/d1: Glide Down 1

When the foot switch is pressed, the pitch changes continuously up (down) to a semi tone. Release the pedal to return to the original pitch.

u2: Glide Up 2/d2: Glide Down 2

When the foot switch is pressed, the pitch changes continuously up (down) to a whole tone. Release the pedal to return to the original pitch.

u3: Glide Up 3/d3: Glide Down 3

When the foot switch is pressed, the pitch changes continuously up (down) to a perfect fourth. Release the pedal to return to the original pitch.

Chapter 2 Creating Your Own Settings (Patches)

u4: Glide Up 4/d4: Glide Down 4

When the foot switch is pressed, the pitch changes continuously up (down) to a perfect fifth. Release the pedal to return to the original pitch.

u5–u8: Glide Up 5–8/d5–d8: Glide Down 5–8

When the foot switch is pressed, the pitch changes continuously up (down) to one octave. Release the pedal to return to the original pitch.

The higher the numeral set, the less time it takes for the change in pitch to be completed.

V1–V4: Vibrato 1–4

Pressing the pedal applies vibrato (an effect that changes the pitch cyclically). The effect deepens as the value is increased

* When using the expression pedal for this effect, the depth of the vibrato changes with the pedal angle.

b1: Pitch Bend 1

When the pedal is pressed, the pitch changes up to a perfect fourth (max.).

b2: Pitch Bend 2

When the pedal is pressed, the pitch changes up to a perfect fifth (max.).

b2: Pitch Bend 3

When the pedal is pressed, the pitch changes up to one octave (max.).

b4: Pitch Bend 4

When the pedal is pressed, the pitch changes down to a semi tone (max.).

b5: Pitch Bend 5

When the pedal is pressed, the pitch changes down to a whole tone (max.).

b6: Pitch Bend 6

When the pedal is pressed, the pitch changes down to one octave (max.).

* When “POLY” (p. 14) is selected as the transmission mode, the changes in pitch with Glide and Pitch Bend occur in semitone steps whenever two or more notes are played together, and Vibrato does not function.
* MIDI Pitch Bend messages are used for Glide and Pitch Bend. If the change in pitch exceeds the BEND RANGE (p. 23) set for Glide or Pitch Bend, the Glide or Pitch Bend is cut off and retriggered.
When using Glide or Pitch Bend, have the bend range set to 24 or Chromatic (C1–C3).
However, if BEND RANGE MAX (p. 32) is set to 12, Glide and Pitch Bend are retriggered if the pitch rises or falls an octave or more.

Shifting the Pitch of the Sound (TRANSPOSE)

On the GI-20, you can shift the pitch, in semitone steps, of what is output over MIDI relative to which is actually played. This transposition can be set individually for each string, and can be any amount from three octaves below the original pitch to two octaves above it. This function is called "TRANSPOSE."

This allows you to perform with open tuning, drop tuning, and other alternative tunings without having to actually change the guitar's own tuning.

1. Turn the PARAMETER knob to "TRANSPOSE."

2. Press [TUNER (STRING SEL)] to select the string whose pitch you want to change.

The string number changes each time you press [TUNER (STRING)], cycling through ALL → 1 → 2 → 3 → 4 → 5 → 6 → ALL...

Select "ALL" if setting all of the strings to the same value.

3. After selecting the string whose pitch you want to change, press [PATCH/VALUE] to change the setting.

You can set the TRANSPOSE settings value in a range from -36 (down three octaves) to 24 (up two octaves).

-36 (-3 octaves)

24 (+2 octaves)

* If notes whose pitches are changed using the TRANSPOSE function are in registers that are unplayable using MIDI messages, the MIDI messages in the expressable range above or below that octave are transmitted. For example, the sound of the bass's fourth string (E) lowered by three octaves cannot be played using MIDI messages, so the MIDI message for the note lowered two octaves is transmitted instead.

4. Repeat Steps 2 and 3 for any other strings you want to set.

1. If you want to save the settings, carry out the Write procedure (p. 26).

* If you do not want to save the settings, turn the PARAMETER knob to return to "PLAY MODE."

1. When you have finished making the settings, turn the PARAMETER knob to return to "PLAY MODE."

Setting the Range in Which Pitches Are Changed (BEND RANGE)

The GI-20 can send continuous pitch changes obtained with techniques such as bending, finger vibrato, tremolo bar usage, and sliding to an external device. This is done using MIDI Pitch Bend Change messages.

Setting Bend Range to as large a value as possible will help enable smooth pitch changes in a wider range. The settable range varies according to the receiving sound module. For equipment having a different settable width in the bend up and down directions, match the setting to the narrowest value.

About messages that notify the external MIDI instrument of the Bend Range and prompt change

The setting called Bend Range must be matched up on the sending and receiving instruments.

The GI-20 normally informs the external MIDI device of the Bend Range setting on the GI-20, and sends a message prompting change every time the patch is switched.

This means that the Bend Range value on the sound module can be set automatically every time the patch is changed simply by matching the maximum Bend Range value that can be set on the external MIDI sound module to the GI-20.

The messages used here are MIDI RPN (Registered Parameter Number) “Pitch Bend Sensitivity” messages (Control Change messages No. 100, No. 101, No. 6, and No. 38).

If you are using an external MIDI sound module which cannot recognize such messages, manually change Bend Range on the external device to the same value on the GI-20. Refer to the Owner's Manuals for the external sound module for information about its MIDI specifications.

* If the transmission mode is set to POLY, the MIDI messages transmitted when two or more strings are played simultaneously use semitone steps, which disallows string bending, slide, and certain other techniques. For more on the transmission mode settings, refer to “Setting the Transmission Mode” (p. 14).

* When Glide or Pitch Bend is selected as the foot switch or expression pedal Assign (p. 19) setting, and the BEND RANGE setting is within the range of the Glide or Pitch Bend range, the Glide or Pitch Bend will cut out and be retriggered.

Setting the Bend Range

1. Turn the PARAMETER knob to "BEND RANGE."

1. Press [TUNER (STRING)] to select the string whose bend range you want to change.

The string number changes each time you press [TUNER (STRING)], cycling through ALL → 1 → 2 → 3 → 4 → 5 → 6 → ALL...

Select "ALL" if setting all of the strings to the same value.

1. Press [PATCH/VALUE] to change the value.
2. Repeat Steps 2 and 3 for any other strings you want to set.
3. If you want to save the settings, carry out the Write procedure (p. 26).

* If you do not want to save the settings, turn the PARAMETER knob to return to "PLAY MODE."

1. When you have finished making the settings, turn the PARAMETER knob to return to "PLAY MODE."

Settings That Can Be Selected With BEND RANGE

1, 2, 4, 5, 7, 12, 24

(Ex.) 12 (1 octave)

One of the above values is selected (1 = semitone, 12 = one octave)

* You cannot select 24 when BEND RANGE MAX (p. 32) is set to 12.

With the GI-20, you can select “Chromatics” for the bend range. When the Chromatics (C1–C3) are selected, if you use string bending or other techniques that bend the guitar or bass pitch, the changes in pitch transmitted in the MIDI messages are made in semitone steps.

* A BEND RANGE value of 12 or 24 is transmitted when the chromatics are selected.

refer to "BEND RANGE MAX" (p. 32)

C1: Chromatic Type 1

When the pitch changes, the currently-heard sound will not stop; it will merely change in pitch. There is no separate attack sound when the pitch changes. This is a change similar to the one you hear with the slurred playing of a recorder.

C2: Chromatic Type 2

When the pitch changes, the sound for the new pitch will be started over, or "retriggered." Thus, whenever the pitch changes, you will hear a new attack. If the retrigger occurs as a string's vibration is trailing off (decaying), the retriggered note will play at an appropriately reduced volume.

C3: Chromatic Type 3

This is basically similar to “Type 2,” but differs in that the attenuation of the string's vibration is not reflected in the retriggered sound; instead, the retriggered sound is the same as that when the string was played originally.

Switching Sounds on External Devices (PRG CHANGE)

You can transmit Bank Select messages (Control Change #0, #32) and Program Change messages by switching the GI-20's patches.

This enables you to switch sounds from external sound modules and patches of guitar effects processors.

When the transmission mode (p. 14) is set to MONO, these messages are transmitted separately for each individual string.

* The Bank Select messages and Program Change messages set here are not transmitted when PC MASK (p. 29) is set to "On."

1. Turn the PARAMETER knob to "PRG CHANGE."

2. Press [SELECT] to select the parameter that is to be changed.

The setting is changed each time you press [SELECT], cycling through Bank Select MSB (CC #0) → Bank Select LSB (CC #32) → Program Change in that sequence.

The display indicators light up as shown below according to the parameter being set.

Bank Select MSB (CC#0)

* This was set to "440.0 Hz" when the unit left the factory.
* The reference pitch is a system parameter. It is saved automatically when the TUNER is turned off, even without the Write procedure being carried out, and the settings values are applied to all patches.
* The reference pitch is output from MIDI OUT as the RPN Channel Fine Tuning each time patches are switched.

1. Press [SELECT].
2. Play an open note on the string you want to tune.

The name of the note closest to the pitch of the string you've played appears in the display.

* Be sure to play only the string to be tuned.

1. As you watch the display, tune the string until only the center green indicator is lit.

1. Repeat Steps 6 and 7 to tune all of the other strings.
2. When you have finished tuning, press [TUNER (STRING)] to return to "PLAY MODE."

Preventing Transmission of Program Change Messages (PC MASK)

You can stop transmission of the Bank Select messages and Program Change messages set in “Switching Sounds on External Devices” (p. 25) for all patches.

1. Turn the PARAMETER knob to "PC MASK."

2. Press [PATCH/VALUE] to change the value.

The Program Change messages and Bank Select messages set in “Switching Sounds on External Devices” (p. 25) are transmitted.

3. When you have finished making the setting, turn the PARAMETER knob back to "PLAY MODE."

* PC MASK is a system parameter. It is saved automatically when the PARAMETER knob is turned, even without the Write procedure being carried out, and the settings values are applied to all patches.

Saving the Patches and System Parameters to an External Device (BULK DUMP)

Settings for all patches-as well as all system parameter settings-can be transferred in and out of the GI-20 using MIDI or USB. You can also save patches externally to equipment that can record MIDI data. For this kind of operation, the GI-20 uses MIDI messages called “System Exclusive messages.” Each System Exclusive message can be interpreted only by the device for which it is intended.

System Exclusive data sent from the GI-20 can be stored in a MIDI sequencer using the sequencer's realtime recording or bulk librarian function. You can also send/receive System Exclusive data directly from one GI-20 to another by connecting the two via MIDI.

MEMO

Transmitting the GI-20's data using Exclusive messages is referred to as "bulk dump," while using Exclusive messages to receive data is known as "bulk load."

1. Connect the GI-20's MIDI OUT to the MIDI IN on the external device.

Alternatively, use a USB cable to connect the GI-20 to your computer.

* Bulk data is output simultaneously from the MIDI OUT and USB connectors.

2. Turn the PARAMETER knob to "BULK."

1. Confirm that "dP" (DUMP) is indicated in the display. If something else is indicated, press [SELECT (EXIT)] and select "dP" (DUMP).

1. Begin recording on the external device being used to receive the data.

5. Press [WRITE].

The data is transmitted to the external device from the MIDI OUT and USB connectors.

The following appears in the display during transmission.

Flash

When the display changes back to "dP," the transmission is finished.

1. If using a sequencer as the receiving device, stop recording.
2. When you have finished the bulk dump, turn the PARAMETER knob back to "PLAY MODE."

Receiving Saved Data Using MIDI (BULK LOAD (MIDI))

Carrying out BULK LOAD automatically overwrites the settings data stored in the receiving device. Note that this will result in the loss of the data stored up to that time.

1. Connect the external device's MIDI OUT to the MIDI IN on the GI-20.
2. Turn the PARAMETER knob to "BULK."

1. Press [SELECT] to select "LM" (LOAD (MIDI)).

1. Transmit the data from the external device.

The following appears in the display during reception.

When the display changes back to "LM," reception is finished.

1. When you have finished the bulk load, turn the PARAMETER knob back to "PLAY MODE."

* If you change to another screen (by pressing [SELECT] or by turning the PARAMETER knob) while the data is being received, any data that's been received won't be loaded into the GI-20.

If necessary, start the Bulk Load procedure over from the beginning.

When the data is received correctly, the dot on the display will light.

Receive Saved Data Through USB (BULK LOAD (USB))

Carrying out BULK LOAD automatically overwrites the settings data stored in the receiving device. Note that this will result in the loss of the data stored up to that time.

1. Use a USB cable to connect the computer and the GI-20.
   * You cannot connect two GI-20s using a USB cable. Use a MIDI cable to connect GI-20s to each other.
2. Start up the application on your computer that will be handling the bulk data.
3. Turn the PARAMETER knob to "BULK."

1. Press [SELECT] to select "Lu" (LOAD (USB)).

1. Transmit the data from the computer.

The following appears in the display during reception.

When the display changes back to "Lu," reception is finished.

1. When you have finished the bulk load, turn the PARAMETER knob back to "PLAY MODE."

* If you change to another screen (by pressing [SELECT] or by turning the PARAMETER knob) while the data is being received, any data that's been received won't be loaded into the GI-20.

If necessary, start the Bulk Load procedure over from the beginning.

When the data is received correctly, the dot on the display will light.

Reducing the Size of a MIDI Pitch Bend Message (BEND DATA THIN)

The Bend Data Thin Function

With the guitar, the finger vibrato technique can be used to produce organic vibratos with amplitude and speed that can be freely varied-something that's very hard to do with a keyboard.

When creating sequencer data, the GI-20 records such finger vibratos, sliding, and tremolo bar usage as MIDI Pitch Bend messages. As a result of this, the MIDI performance message that is output contains a large number of Pitch Bend messages. In some cases, however, these Pitch Bend messages can greatly inflate the amount of data and exceed the sequencer's memory capacity.

The Bend Data Thin function is available to keep this to a minimum.

The amount of Pitch Bend messages that are sent can be reduced by using the Bend Data Thin function. Although the smoothness of pitch changes deteriorates, this can reduce the amount of MIDI data.

* With the factory settings, Bend Data Thin is set to "Off."

1. Turn off the power to the GI-20.
2. Hold down [WRITE] and turn on the power.
3. Press [SELECT], causing the first two indicators on the left of the display to light up.

The first two indicators light when you select BEND DATA THIN.

1. Press [PATCH/VALUE] to select "On."

If you do not want to reduce the size of the Pitch Bend Message being transmitted, select "oF" (Off).

On

Off

1. Turn the power off.

Reducing the Amount of Control Change Data Transmitted (RECEIVE CONTROL CHANGE DATA THIN)

Receive Control Change Data Thin Function

When the GI-20's transmission mode is set to "MONO" (p. 14), the Control Change messages received at MIDI IN are increased due to the output from all of the six strings. If a large number of Control Change messages are being received at the same time, it may cause data processing to stop, with the error message (p. 37) being displayed as a result. If this occurs, you can use the Receive Control Change Data Thin function to thin out some of the Control Change messages received at MIDI IN, while giving higher priority to the most recently received messages.

* With the factory settings, Receive Control Change Data Thin is set to "On."

1. Turn off the power to the GI-20.
2. Hold down [WRITE] and turn on the power.
3. Press [SELECT], causing the first three indicators on the left of the display to light up.

The first three indicators on the left of the display light when you select RECEIVE CONTROL CHANGE DATA THIN.

1. Turn the power off.

Limiting the Extent of the Bend Range (BEND RANGE MAX)

Although the GI-20 has a maximum bend range setting of 24, unless the GI-20 and your sound module feature the same bend range settings, you may find that functions such as pitch bend and string bending do not work well.

However, some sound modules have only a narrow range of settings you can make. In such situations, use BEND RANGE MAX.

BEND RANGE MAX helps keep poor operation to a minimum by limiting the GI-20's bend range to that of the connected sound module.

For example, setting BEND RANGE MAX to 12 limits the maximum value for the BEND RANGE output by the GI-20 to 12.

* For more on your sound module's specifications, refer to the owner's manual that came with it.
* With the factory settings, this is set to "24."
* When BEND RANGE MAX is set to "12," the sound module is retriggered if the pitch is changed by an octave with pitch bend or glide.
Take note of this when Glide or Pitch Bend is assigned (p. 19) to the foot switch or expression pedal.

1. Turn off the power to the GI-20.
2. Hold down [WRITE] and turn on the power.
3. Press [SELECT], causing the first four indicators on the left of the display to light up.

1. Press [PATCH/VALUE] to select "12" or "24."

If you do not want to limit the bend range, set this to "24."

1. Turn the power off.

Selecting the Type of USB Driver

When using the GI-20 when it is connected to a computer, you can select from two types of drivers.

* Be sure to set the GI-20's driver so that it matches the driver used by the computer. In some cases, the driver may not function properly.

SP: VENDER SPECIFIC:

The special driver on the CD-ROM included with the GI-20 is used, providing faster, more stable MIDI transmission. Normally, this is what you should use.

GE: GENERIC:

Use this setting when using the standard MIDI driver that came with your OS.

* With the factory settings, USB DRIVER is set to "VENDER SPECIFIC."

1. Turn off the power to the GI-20.
2. Hold down [WRITE] and turn on the power.
3. Press [SELECT], causing only the leftmost indicator of the display to light up.
   Only the leftmost indicator light when you select USB DRIVER TYPE.

1. Press [PATCH/VALUE] to select "SP" or "GE."

2. Turn the power off.

The USB driver setting becomes effective the next time you turn on the GI-20.

Chapter 4 Other Functions

Reset to Default Factory Settings (Factory Reset)

The procedure for restoring the GI-20's internal settings to the state they were in when the unit left the factory is called a "Factory Reset." This procedure allows you to return the patch parameters for Patches 01–50, pickup sensitivity settings, MIDI transmission, and other system parameters to their original factory values.

Here, you can set the GUITAR/BASS switch to select patch content that is optimized for the use of either a guitar or bass.

* With the factory settings, this is set to patches that are optimized for the guitar.

The Factory Reset operation undoes any settings you have changed and discards any edits you have made to its patches. If you have settings or patches you wish to preserve, use the Bulk Dump operation (p. 29) to save them, before performing the Factory Reset operation.

1. Turn off the power to the GI-20.
2. Set GUITAR/BASS to match the instrument you are using (guitar or bass).
3. Hold down [TUNER (STRING SEL)] and turn on the power.

"in" appears in the display.

Chapter 5 Appendices

Troubleshooting

If there is no sound or other operational problems occur, first check through the following solutions. If this does not resolve the problem, then contact your dealer or a nearby Roland service station.

The volume fluctuates from one string to another

☐ Are the "SENSITIVITY" settings correct for each string?
→ Adjust the settings as required. (p. 11)
☐ Is the GUITAR/BASS switch on the rear panel set correctly?
→ Switch to GUITAR if you are using a guitar; if using a bass, switch this to BASS. (p. 10)

Pitch doesn't rise when using Pitch Glide (or the expression pedal Pitch function)

☐ Functions that vary pitch continuously may experience a limited range of change during rising pitch due to the register.
If a limitation is encountered, use with a narrower width of change. (p. 22)

Pitch doesn't change smoothly

☐ Is "BEND RANGE" (p. 23) set to "Chromatic Type 1-3"?
→ Set BEND RANGE to anything other than Chromatic Type for patches that require continuous changes in pitch. (p. 23)

☐ Is data being sent in the Poly mode (p. 14)?

→ When transmitting in the Poly mode, pitch changes during chord performances are in semitone steps. Play with single notes, or use the Mono mode to send data.

☐ Is the Bend Data Thin function (p. 31) in use?

→ Using this function may result in a slight loss of smoothness when pitch changes, even during normal play. Do not use the Bend Data Thin function when it is not needed.

☐ Is BEND RANGE MAX (p. 32) or BEND RANGE (p. 23) set to anything other than 24?

→ With BEND RANGE MAX set to anything other than 24, if Glide Up/Down 5–8 or Pitch Bend 3 or 6 is used in Assign (p. 19), then changing the pitch by an octave causes retriggering. Set BEND RANGE MAX and BEND RANGE to 24.

☐ Is "BEND RANGE" (p. 23) set to "1" or "2"?
→ When matching with sending and receiving, use as large a value as possible.

The sound doesn't vary when the settings are changed

☐ Is the setting being changed one of the parameters that can be made independently for each string, and is the setting affecting only a particular string?
→ Use [TUNER (STRING)] to select "ALL."

No sound from the external sound module

Do the MIDI channels for sending and receiving match?
→ Make sure the MIDI channels match. (p. 14)
☐ The volume level of the external sound module may have been lowered by a MIDI Volume message (Control Change No. 7) sent from the GI-20.
→ Raise the volume on the GK series pickup.
☐ Make sure the volume on the GK series pickup or the expression pedal has not been turned down too low.
→ Use the controls to increase the volume.
☐ Is "STRING MUTE" (p. 26) set to "On"?
→ If "STRING MUTE" is set to "On", note messages cannot be transmitted. Please change it to "Off."
☐ The value of Bank Select in "PRG CHANGE" (p. 25) is set to the value that does not match the sound module.
→ Check the Patch setting on the GI-20 and the specifications of the Bank Select on the sound module.

The external sound module plays only one string (some strings can't be heard)

☐ Is the GI-20 using the Mono mode to send data to a sound module which cannot simultaneously receive data on six MIDI channels?
→ For such sound module, send data in the Poly mode. (p. 14)

Notes in a bass register not on the guitar/bass cannot be played

→ Output from MIDI OUT can be transposed as desired by changing the TRANSPOSE setting. (p. 23)

The pitch is wrong (out of tune with the guitar/bass)

☐ Is MIDI Bend Range the same for both sending and receiving?
→ If the pitch is off, adjust the BEND RANGE setting. (p. 23)
☐ Is the GUITAR/BASS switch on the rear panel set correctly?
→ Switch to GUITAR if you are using a guitar; if using a bass, switch this to BASS. (p. 10)

Problems occur after switching GI-20 patches. For example, the connected sound module no longer produces sound, or the sound won't stop, or modulation is applied constantly and won't switch off.

☐ When patches are switched, no signal is transmitted to restore the Control Change value transmitted with the previous patch. Therefore, if the same assign settings are used for both of the patches prior to and following the switch, the status of the controllers is carried over. However, if the assign settings are different for the patch you are switching to, you cannot restore the value for the Control Change transmitted with the earlier patch. (p. 20)

The Note messages input to the sequencer don't look like the scale that is actually played

To start playing sounds rapidly and achieve smooth changes in pitch, the GI-20 transmits pitch as a combination of Note messages and Pitch Bend messages. This means that if only the Note messages are examined on the sequencer's microscope (event list) screen, the on-screen information may differ from what is actually performed.
→ If continuous pitch change is not required, you can create data that is displayed more faithfully by setting the BEND RANGE to “Chromatic Type 1–3.” (p. 23)

Error Messages

If you attempt an incorrect operation or if an operation could not be executed, the display will indicate an error message. Refer to this list and take the appropriate action.

Reason Reception of bulk data in the Bulk Load screen was immediately followed by reception of subsequent bulk data, so the data received after by the GI-20 could not be processed.

Action Switch the screen for a moment, then select the Bulk Load screen again and retransmit the bulk data. In case of transmitting the bulk data more than twice, please make sure that the previous data was firmly received and transmit another data.

Reason There was an error in the bulk data received in the Bulk Load screen.

Action Switch the screen for a moment, then select the Bulk Load screen again, and transmit the bulk data again after correcting the data to transmit to the GI-20.

Reason 1 The GI-20 stopped processing due to an attempt to transmit numerous MIDI messages from the GI-20 at one time. (The GI-20's MIDI IN/OUT connectors may be connected with a single MIDI cable.)

Action 1 Check the connections.

Reason 2 Soft Thru on the sequencer connected to the MIDI IN/OUT is set to ON.

Action 2 Set the sequencer's Soft Thru to OFF.

Reason The data transmitted from the GI-20's USB connector was not received by the connected computer, preventing the GI-20 from processing transmissions.

Action Confirm that the USB-connected device is capable of receiving the data properly.

Reason The GI-20's MIDI IN connector received many MIDI messages at once, and the GI-20 was unable to process the data.

Action Reduce the amount of MIDI data transmitted to the GI-20's MIDI IN.

Reason [SELECT] was pressed while exclusive data was being transmitted via the computer's USB connector, so the exclusive data could not be received properly.

Action The sound module or other device connected to the GI-20's MIDI OUT may not be operating correctly. Turn off the power to the sound module or other device, then turn it back on again.

Roland Exclusive Messages

1. Data Format for Exclusive Messages

Roland's MIDI implementation uses the following data format for all Exclusive messages (type IV):

Byte	Description
F0H	Exclusive Status
41H	Manufacturer ID (Roland)
DEV	Device ID
MDL	Model ID
CMD	Command ID
[BODY]	Main data
F7H	End of exclusive

•MIDI status: F0H, F7H

An Exclusive message must be flanked by a pair of status codes, starting with a Manufacturer ID immediately after F0H (MIDI version 1.0).

•Manufacturer ID: 41H

The Manufacturer ID identifies the manufacturer of a MIDI instrument that sends an Exclusive message. Value 41H represents Roland's Manufacturer ID.

- Device ID: DEV

The Device ID contains a unique value that identifies individual devices in the implementation of several MIDI instruments. It is usually set to 00H-0FH, a value smaller by one than that of a basic channel, but value 00H-1FH may be used for a device with several basic channels.

- Model ID: MDL

The Model ID contains a value that identifies one model from another. Different models, however, may share an identical Model ID if they handle similar data.

The Model ID format may contain 00H in one or more places to provide an extended data field. The following are examples of valid Model IDs, each representing a unique model:

01H

02H

03H

00H, 01H

00H, 02H

00H, 00H, 01H

•Command ID: CMD

The Command ID indicates the function of an Exclusive message. The Command ID format may contain 00H in one or more places to provide an extended data field. The following are examples of valid Command IDs, each representing a unique function:

01H

02H

03H

00H, 01H

00H, 02H

00H, 00H, 01H

• Main data: BODY

This field contains a message to be exchanged across an interface. The exact data size and content will vary with the Model ID and Command ID.

2. Address-mapped Data Transfer

Address mapping is a technique for transferring messages conforming to the data format given in Section 1. It assigns a series of memory-resident records—waveform and tone data, switch status, and parameters, for example, to specific locations in a machine-dependent address space, thereby allowing access to data residing at the address a message specifies.

Address-mapped data transfer is therefore independent of models and data categories. This technique allows use of two different transfer procedures: one-way transfer and handshake transfer.

- One-way transfer procedure (See Section 3 for details.)

This procedure is suited to the transfer of a small amount of data. It sends out an Exclusive message completely independent of the receiving device's status.

Connection Diagram

Connection at point 2 is essential for "Request data" procedures. (See Section 3.)

- Handshake-transfer procedure (This device does not use this procedure)

This procedure initiates a predetermined transfer sequence (handshaking) across the interface before data transfer takes place. Handshaking ensures that reliability and transfer speed are high enough to handle a large amount of data.

Connection Diagram

Connection at points 1 and 2 is essential.

Notes on the above procedures

* There are separate Command IDs for different transfer procedures.
* Devices A and B cannot exchange data unless they use the same transfer procedure, share identical Device ID and Model ID, and are ready for communication.

3. One-way Transfer Procedure

This procedure sends out data until it has all been sent and is used when the messages are so short that answerbacks need not be checked.

For longer messages, however, the receiving device must acquire each message in time with the transfer sequence, which inserts 20 milliseconds intervals.

Types of Messages

Message	Command ID
Request data 1	RQ1 (11H)
Data set 1	DT1 (12H)

- Request data #1: RQ1 (11H) (This device does not use this procedure)

This message is sent out when there is a need to acquire data from a device at the other end of the interface. It contains data for the address and size that specify designation and length, respectively, of data required.

On receiving an RQ1 message, the remote device checks its memory for the data address and size that satisfy the request.

If it finds them and is ready for communication, the device will transmit a "Data set 1 (DT1)" message, which contains the requested data. Otherwise, the device won't send out anything.

* The size of the requested data does not indicate the number of bytes that will make up a DT1 message, but represents the address fields where the requested data resides.
* Some models are subject to limitations in data format used for a single transaction. Requested data, for example, may have a limit in length or must be divided into predetermined address fields before it is exchanged across the interface.
* The same number of bytes comprises address and size data, which, however, vary with the Model ID.
* The error-checking process uses a checksum that provides a bit pattern where the last 7 bits are zero when values for an address, size, and that checksum are summed.

• Data set 1: DT1 (12H)

This message corresponds to the actual data transfer process.

Because every byte in the data is assigned a unique address, a DT1 message can convey the starting address of one or more bits of data as well as a series of data formatted in an address-dependent order.

The MIDI standards inhibit non real-time messages from interrupting an Exclusive one. This fact is inconvenient for devices that support a “soft-thru” function. To maintain compatibility with such devices, Roland has limited the DT1 to 256 bytes so that an excessively long message is sent out in separate ‘segments’.

* A DT1 message is capable of providing only the valid data among those specified by an RQ1 message.
* Some models are subject to limitations in data format used for a single transaction. Requested data, for example, may have a limit in length or must be divided into predetermined address fields before it is exchanged across the interface.
* The number of bytes comprising address data varies from one Model ID to another.
* The error-checking process uses a checksum that provides a bit pattern where the last 7 bits are zero when values for an address, size, and that checksum are summed.

• Example of Message Transactions

•Device A sending data to Device B

Transfer of a DT1 message is all that takes place.

•Device B requesting data from Device A

Device B sends an RQ1 message to Device A.

Checking the message, Device A sends a DT1 message back to Device B.

Installing & Setup the Driver

In order to use the GI-20 USB, you must first install the USB MIDI driver. The USB MIDI Driver is included in the “GI-20 Driver CD-ROM.”

■ What is USB MIDI Driver?

The GI-20 Driver is software which passes data between the GI-20 and the application (sequencer software etc.) that is running on the USB-connected computer.

The GI-20 Driver sends data from the application to the GI-20, and passes data from the GI-20 to the application.

☐ Using the procedure for "Deleting the driver"(p. 67), delete the USB audio device driver installed in your computer, and then re-install the GI-20 driver as described in "Installing & setting Up the Driver (Windows)"(p. 46).

Also check whether there is any “Other devices” in “Device Manager” or “Unknown device” in “Universal Serial Bus Controllers”. If you find any, delete them.

☐ Is OMS or FreeMIDI installed?

The GI-20 driver cannot be installed unless OMS or FreeMIDI are installed. Please install OMS or FreeMIDI.

GI-20 is not detected when making OMS or FreeMIDI settings

Is the GI-20 detected?

Turn the power of the GI-20 off, then on again.

Reconnect the USB cable.

If other USB devices are connected, connect only the GI-20.

It is possible that the Macintosh did not correctly detect and initialize the GI-20. Leave the GI-20's USB cable connected, and restart your Macintosh. If it is still not detected, shut down your Macintosh, and then restart it.

The GI-20 will not be detected if it is connected to the USB connector on the Macintosh keyboard.

Please connect the GI-20 to a USB connector on the Macintosh itself.

Are you using only OMS?

OMS will not work properly if FreeMIDI is installed in the same system. Delete FreeMIDI-related files from the Extensions folder.

"Find new hardware wizard" does not execute automatically

The "Insert Disk" dialog box does not appear

"Find new hardware wizard" ends before the process is completed

☐ It may take about 15 seconds (or more) after the USB cable is connected for the GI-20 to be detected.
☐ Is the USB cable connected correctly?
Make sure that the GI-20 and your computer are correctly connected via a USB cable.
☐ Is USB enabled on your computer?
Refer to the operation manual for your computer, and make sure that USB is enabled.

☐ Does your computer meet the USB specifications?

If you are using a computer that does not fulfill the electrical requirements of the USB specifications, operation may be unstable. In this case, you may be able to solve the problem by connecting a USB hub.

If the above actions do not solve the problem, it is possible that the GI-20 has been incorrectly detected by the computer.

As described in "", "delete the incorrect device information, then re-install the driver.

→ "Installing & Setting Up the Driver (Windows)" (p. 46)

"Found unknown device" appears even though you installed the driver

If your computer or USB hub has two or more USB connectors, and you connect the GI-20 to a USB connector to which the GI-20 has never been connected before, the “Unknown device” dialog box may appear even on a computer onto which you have already installed the driver.

Refer to "Installing & Setting Up the Driver (Windows)"(p. 46), and install the driver once again. This is not a malfunction.

If the “Found unknown device” dialog box appears even though the GI-20 is connected to the same USB connector as before, it is possible that the computer has detected the GI-20 incorrectly.

As described in "", "delete the incorrect device information, then re-install the driver.

→ "Installing & Setting Up the Driver (Windows)" (p. 46)

An "Unknown driver found" dialog box appears, and you are unable to install the driver

Device Manager shows “?”, “!”, or “USB Composite Device”

Driver is not installed correctly

It is possible that the computer has detected the GI-20 incorrectly.

For EU Countries

The Ground Truth image displays a single, solid horizontal line. According to Rule 2 (UNDERSCORE & LINE RULES), this is a stylistic or background line, not a placeholder underscore. Therefore, the OCR result must ignore it and output nothing or only meaningful text. The provided OCR content is "____", which consists of four underscores. This is an incorrect interpretation of the line as a placeholder, violating the rule that stylistic lines must be ignored. The OCR has hallucinated underscores where none should exist based on the GT's visual context. Hence, the OCR result is inconsistent with the Ground Truth.

This symbol indicates that in EU countries, this product must be collected separately from household waste, as defined in each region. Products bearing this symbol must not be discarded together with household waste.

This product complies with the requirements of EMC Directive 2004/108/EC.
