Power Supply
- Do not connect this device to the same electrical outlet as an inverter-controlled device such as a refrigerator, microwave oven, or air conditioner, or a device that contains an electric motor. Depending on how the other device is used, power supply noise could cause this device to malfunction or produce noise. If it is not practical to use a separate electrical outlet, please connect this device via a power supply noise filter.
- 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 you make connections, you must switch off the power on all devices to prevent malfunction and/or speaker damage.
Location
- If this device is placed near devices that contain large transformers, such as power amps, hum may be induced in this device. If this occurs, move this device farther away or change its orientation.
- If this device is operated near a television or radio, color distortion may be seen in the television screen or noise may be heard from the radio. If this occurs, move this device farther away.
- Keep your cell phone powered off or at a sufficient distance from this device. If a cell phone is nearby, noise may be heard when a call is received or initiated, or during conversation.
- 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.
- If you move this device between locations of radically different temperature or humidity, water droplets (condensation) may form inside the device. Using the device in this condition will cause malfunctions, so please allow several hours for the condensation to disappear before you use the device.
- Do not leave objects on top of the keyboard. This can cause malfunctions such as failure to sound.
- Depending on the material and temperature of the surface on which you place the unit, its rubber feet may discolor or mar the surface. You can place a piece of felt or cloth under the rubber feet to prevent this from happening. If you do so, please make sure that the unit will not slip or move accidentally.
Care
- 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.
- If water droplets should adhere to this device, immediately wipe them off using a soft dry cloth.
- Do not use solvents such as benzene, thinner, or alcohol, since these can cause deformation or color change.
Servicing
- If you return this device for servicing, the contents of memory may be lost. Please store important contents on a USB memory, or make a note of the contents. We take utmost care to preserve the contents of memory when performing service, but there may be cases when the stored content cannot be recovered because the memory section has malfunctioned. Please be aware that we cannot accept responsibility for the recovery of lost memory content or for any consequences of such loss.
Other Cautions
- Stored content may be lost due to a malfunction of the device or because of inadvertent operation. You should back up important content on a USB memory as a safeguard against such loss.
- We cannot accept responsibility for the recovery of any content lost from internal memory or USB memory, or for the consequences of such loss.

Do not use benzine, record cleaner spray or solvents of any kind.
- Do not bend the disc. Bending discs may prevent proper reading and writing of data, and may further result in malfunction.
Floppy Disk Handling (Using Optional Floppy Disk Drive)
- Floppy disks contain a plastic disk with a thin coating of magnetic storage medium. Microscopic precision is required to enable storage of large amounts of data on such a small surface area. To preserve their integrity, please observe the following when handling floppy disks:
- Never touch the magnetic medium inside the disk.
- Do not use or store floppy disks in dirty or dusty areas.
- Do not subject floppy disks to temperature extremes (e.g., direct sunlight in an enclosed vehicle). Recommended temperature range: 10–50 degrees C (50–122 degrees F).
- Do not expose floppy disks to strong magnetic fields, such as those generated by loudspeakers.
- Floppy disks have a "write protect" tab which can protect the disk from accidental erasure. It is recommended that the tab be kept in the PROTECT position, and moved to the WRITE position only when you wish to write new data onto the disk.

text_image
Rear side of the disk Write Protect Tab Write (can write new data onto disk) Protect (prevents writing to disk)- The identification label should be firmly affixed to the disk. Should the label come loose while the disk is in the drive, it may be difficult to remove the disk.

Ground Terminal POWER DC IN USE ROLLAR PSB-R ADAPT ONLY Cord Hook (AC Adaptor) Power Cord
To prevent the inadvertent disruption of power to your unit (should the plug be pulled out accidentally), and to avoid applying undue stress to the AC adaptor jack, anchor the power cord using the cord hook, as shown in the illustration. Even if the cord is fastened, strong tension applied to the cord may cause it to be damaged or broken. Be careful not to pull the cord accidentally, or to apply strong pressure to it.

Depending on the circumstances of a particular setup, you may experience a discomforting sensation, or perceive that the surface feels gritty to the touch when you touch this device. This is due to an infinitesimal electrical charge, which is absolutely harmless. However, if you are concerned about this, connect the ground terminal (see figure) with an external ground. When the unit is grounded, a slight hum may occur, depending on the particulars of your installation. If you are unsure of the connection method, contact the nearest Roland Service Center, or an authorized Roland distributor, as listed on the "Information" page.
Unsuitable places for connection
•Water pipes (may result in shock or electrocution)
•Gas pipes (may result in fire or explosion)
- Telephone-line ground or lightning rod (may be dangerous in the event of lightning)
Connecting the External Equipment to RD-300GX
The RD-300GX is not equipped with an amplifier or speakers. In order to produce sound, you need to hook up audio equipment such as a monitor speaker or a stereo set, or use headphones.

You can also connect a commercially available CD drive or floppy disk drive (sold separately) to the USB MEMORY connector.
Basic Organization of the RD-300GX
The RD-300GX can be divided into two sections: a controller section and a sound generator section.

text_image
Sound Generator Section Play Controller Section (controllers such as keyboard, pitch bend lever, etc.)Controller Section
This section includes the keyboard, the Pitch Bend/Modulation lever, the panel knobs, the sliders, and any pedal connected to the rear panel. Actions such as pressing and releasing of keys on the keyboard, depressing a pedal, and so forth, are converted to MIDI messages and sent to the sound generator section, or to an external MIDI device.
Sound Generator Section
The sound generator section produces the sound. Here, MIDI messages received from the controller section or external MIDI device are converted to musical signals, which are then output as analog signals from the OUTPUT and PHONES jacks.
Units of Sound
When using the RD-300GX, you will notice that a variety of different categories come into play when working with sounds. What follows is a simple explanation of each sound category.
Tone
The individual sounds used when playing the RD-300GX are referred to as "Tones." Tones are assigned to each part. The Tones also include various groups of percussion instrument assembled into "Rhythm Sets." Each key (note number) of a Rhythm Set will produce a different percussion instrument.
Part
A sound generator of this type which can control multiple sounds using one device is referred to as a multitimbral sound generator. The RD-300GX contains a multitimbral sound generator capable of playing sixteen Tones simultaneously. "Parts" are where Tones that are created when the RD-300GX is used as a sound generator are assigned. Since different Tones can be assigned to each of the Parts and controlled individually, you can have multiple Tones play simultaneously, divide the keyboard into separate ranges and have different Tones sound in the different parts (Split), and enjoy playing ensemble performances.
The sixteen Parts played by the RD-300GX's internal sound generator are referred to as "Internal Parts."
Zone
The RD-300GX features three Parts (UPPER 1, UPPER 2, and LOWER) that you can use for freely controlling the Internal Parts with the RD-300GX's buttons and keyboard. These three Parts that are used for controlling the Internal Parts are collectively known as the "Internal Zone."
Furthermore, you can freely control external MIDI sound generators with the RD-300GX in the same manner as with the Internal Zone. You can likewise control the external MIDI sound generator with the three Parts (UPPER 1, UPPER 2, and LOWER), with this group of three Parts being referred to as the "External Zone." The external MIDI sound generator is assigned to these three Parts for control.

The [DUAL] button has no effect while the EXTERNAL indicator is lit. In order to turn on the External Zone UPPER 2, you must set the MIDI channel for UPPER 2 (p. 55).
Pressing Two TONE SELECT buttons Simultaneously
You can layer two Tones by pressing two TONE SELECT buttons simultaneously.
For example, if you want to layer a piano sound with strings, together press both the [PIANO] button and the [STRINGS] button.
The [DUAL] button's indicator starts to flash, and when you begin playing the keyboard, the piano and strings sounds are layered together.
In this case, the Tone of the button you press first is assigned to UPPER 1, and the other is assigned to UPPER 2; the indicators of the two TONE SELECT buttons will light.

* The steps described above can be performed if the ZONE SELECT indicator UPPER 1 or UPPER 2 is lit.
Playing Different Tones in Two Different Sections of the Keyboard ([SPLIT] Button)
Such a division of the keyboard into right- and left-hand sections is called a "Split," and the key where the division takes place is called the "Split Point."
While in Split mode, a sound played in the right side is called an "Upper Tone," and the sound played in the left side is called a "Lower Tone." The split-point key is included in the LOWER section.
The Split Point has been set at the factory to "B3."

For details on installing the included "Audio Key Utility 2" into your computer, refer to "Audio Key Utility 2 Quick Guide" (separate document).

If no USB memory (sold separately) containing audio files is connected to the RD-300GX, you'll be able to play audio files that are built into the RD-300GX (see the section that follows).
If the connected USB memory does not contain an audio file set created by the "Audio Key Utility 2," you'll be able to assign audio files from USB memory to each key and play them.

You can also change the settings of the audio files assigned to the keys, and change the settings that specify how the audio files will be repeated (p. 46).
The changes you make will be lost if you select another audio file set. If you don't want to delete it, carry out the Write procedure.
Caution when Playing Back Audio Files
Playing back an MP3 file or changing the playback tempo of an audio file places a significant processing burden on the RD-300GX, and in some cases may cause it to be unable to completely process all of the performance data from the keyboard.
If this occurs, you may be able to solve the problem by taking the following actions.
- Use WAV/AIFF format data rather than MP3 format data
- Return the song tempo to its original setting (to 0%)
An MP3 file has little time of the blank at the head and the end of the file. Therefore, the sound might cut off when an MP3 file played repeatedly with Audio Key function.
If this occurs, you may be able to solve the problem by taking the following actions.
- Use WAV/AIFF format data rather than MP3 format data
Performing with Audio Files that are Built Into the RD-300GX
If USB memory (sold separately) containing audio files is not connected, you'll be able to play audio files that are built into the RD-300GX.

Changing the Undulation of the Organ Tone (Rotary Effect)
The Rotary effect is applied to some Organ Tones you can select with the [ORGAN] button. When one of these Tones is selected, you can use the [MULTI EFFECTS] button to change the speed of the rotary effect.
What the rotary effect does is to add a "spinning" effect similar to the sound of an organ using a rotating speaker.
- Press the [ORGAN] button and select the organ Tone.
When a Tone that has the Rotary effect added is selected, the [MULTI EFFECTS] button's indicator flashes.
- Each time pressing the [MULTI EFFECTS] button, switch the speed of the rotary effect between fast and slow rotation.
When the [MULTI EFFECTS] button's indicator flashes, a more fast rotary effect is applied.
When the [MULTI EFFECTS] button's indicator blinks, a slower rotary effect is applied.

To prevent the Rotary effect from being applied, select an effect type other than the Rotary effect and then remove the effect.

You can apply the rotary effect to Tones other than the organ Tones as well.
Disabling the Buttons (Panel Lock)
Once Panel Lock is engaged, all buttons (except for the VOLUME slider, [DISPLAY CONTRAST] knob, Pitch Bend/Modulation lever, Pedals, ONE TOUCH [PIANO] button, and [EXIT/SHIFT] button) will not function. This prevents settings from being changed inadvertently on stage or in other such situations.
1. While holding down the [EDIT] button, and press the [ENTER] button.
Continue holding down the [EDIT] button and [ENTER] button until the following display appears.
| Panel | Locked |

By connecting an external MIDI device to the MIDI OUT connector on the RD-300GX's rear panel, you can then control the external MIDI device with the RD-300GX.
Normally, the RD-300GX will transmit note messages from the MIDI OUT connector, but if you press the [EXTERNAL/INTERNAL] button so the "EXTERNAL" indicator is lit, you'll be able to control various settings on your external MIDI device in addition to transmitting note messages.
You can control internal and external sound generators independently.
If you press the [EXTERNAL/INTERNAL] button so the "EXTERNAL" indicator is lit, the RD-300GX will be in a state where it can control an external MIDI sound module (External Zone). You use the [EXTERNAL/INTERNAL] button to switch between control of the Internal Zone and control of the External Zone. You can also make detailed settings for MIDI messages transmitted to external sound modules.
What's MIDI?
MIDI (Musical Instrument Digital Interface) is a standard specification that allows musical data to be exchanged between electronic musical instruments and computers. By using a MIDI cable to connect devices that have MIDI connectors, you can create an ensemble in which a single MIDI keyboard can play multiple instruments, or change settings automatically as the song progresses.
About MIDI Connectors
The RD-300GX has the following three types of MIDI connector. Their functions differ as described below.

text_image
USB MEMORY MIDI MIDI OUT INMIDI IN Connector
Performance messages from an external MIDI device are received here. These incoming messages may instruct the RD-300GX to play sounds or switch Tones.
MIDI OUT Connector
MIDI messages are transmitted from this connector to an external MIDI device. The RD-300GX's MIDI OUT connector is used for sending the performance data of the controller section as well as data used for saving various settings (Bulk Dump→p. 77).
USB MIDI Connector
Use a commercially available USB cable to connect this to your computer's USB connector. You can use MIDI-compatible software on your computer to transmit SMF files for playback by the RD-300GX, or set up a sophisticated music production system in which MIDI data is transferred between your sequencer software and the RD-300GX.
Connecting to External MIDI Sound Generators

3. Use the ZONE SELECT button to select the Zone for which you want to make settings.
The indicator of the selected Zone will light.
4. Use the [DEC] [INC] buttons to set the value.
Pressing the [DEC] [INC] buttons simultaneously sets the value to “---,” “OFF,” or “0.”
Adjusting the Volume and Pan (Vol/Pan)
Sets the volume and the panning (localizes sound image) for each of the Tones.
The Volume setting is mainly used when multiple tones are playing to obtain the desired balance in volume between each Zone.
The Pan setting positions the sound image of each Zone when the output is in stereo. With an increase in the value for L, more of the sound will be heard as coming from the left side. Similarly, more of the sound will originate at the right if the value of R is increased. When set to 0, the sound is heard as coming from the center.
| Parameter | TX CC# Value | |
| Vol (Volume) | CC07 | --- (OFF), 0–127 |
| Pan (Pan) | CC10 | L64–0–63R, --- (OFF) |
Setting the Amount of Reverb and Chorus (Rev/Cho)
This sets the depth of the reverb and chorus effects.
| Parameter | TX CC# Value | |
| Rev (Reverb) | CC91 | --- (OFF), 0–127 |
| Cho (Chorus) | CC93 | |
Setting the Transposition for Each Individual Zone (Trs)
You can perform with each Zone transposed to a different pitch.
When multiple Zones are set to on, you can create a richer sound by setting the two Tones to different octaves. Also, if the Keyboard Mode is set to Split and you are playing a bass Tone in the lower Part, you can use the Transpose function to play the bass at a lower pitch.
| Parameter | Value |
| Trs (Transpose) | -48 - 0 -+48 |
Setting the Key Range (KRL/KRU)
Set the keyboard range in which each Zone will sound.
This can be used to make notes in different areas of the keyboard play different Tones.
Specify the lower limit (KRL) and upper limit (KRU) of the key range being set.
You can also set this by pressing a specific key and then pressing the [ENTER] button.
| Parameter | Value |
| KRL (Key Range Lower) | A0-C8 |
| KRU (Key Range Upper) |
NOTE
This is effective only when the [SPLIT] button is on (p. 29) in the key range settings.
MEMO
"FUL" is displayed when the [SPLIT] button is set to OFF. In this case, the [SPLIT] button is automatically switched on when the value is changed to something other than "FUL" with the [DEC] [INC] buttons.
NOTE
You cannot set the key range's lower limit higher than the upper limit, nor can you set the upper limit below the lower limit.
MEMO
If you don't want MIDI note data to be transmitted, set the Zone's MIDI OUT Ch to "OFF." (p. 55)
Making Detailed Settings for the Piano Tones (Piano Designer)
You can make detailed settings to adjust the piano sound that's used when you press the ONE TOUCH [PIANO] button (p. 26).
This function is called "Piano Designer."
Furthermore, you can save the changed settings.
NOTE
When the ONE TOUCH [PIANO] button is pressed, all settings other than the Piano Designer settings are switched to their status at the time the RD-300GX's power was turned on. Store any arrangements of settings that you want to keep in Setup (p. 51).

Selecting the Piano Sound (Tone)
This chooses the piano Tone to be selected when the ONE TOUCH [PIANO] button is pressed.
You can choose from the Tones of the TONE SELECT [PIANO] button.
Changing the Amount of Reverb Effect (Reverb Depth)
This does the same thing as the setting described in "Changing the Depth of Reverb Effect" (p. 34), but this setting can be easily accessed by pressing the ONE TOUCH [PIANO] button.
| Parameter | Value Description | |
| Reverb Amount | 0–127 | The reverb effect becomes stronger as the value is increased. |
Opening/Closing the Piano Lid (Lid)
Reproduces the way the brightness of a grand piano's sound is affected by how much the piano's lid is opened.
| Parameter | Value Description | |
| Lid | 1-7 | The lid is opened more as the value is increased, creating a brighter sound. |
Adjusting the Damper Noise (Damper Noise)
This adjusts the damper noise (the sound that occurs when the strings of an acoustic piano are released by pressing the damper pedal).
| Parameter | Value Description | |
| Damper Noise | 0–127 | Increasing this value will increase the sound that is heard when the strings are released. |
Adjusting the Resonance of the Aliquot Strings (Duplex Scale)
This adjusts the sound of the sympathetically vibrating aliquot strings on an acoustic piano.
| Parameter | Value Description | |
| Duplex Scale | 0–127 | Higher values will increase the volume of the sympathetic vibration. |
What are Duplex Scale?
The Duplex Scale is a system of sympathetically vibrating strings sometimes included in grand pianos.
These sympathetically vibrating strings are not struck directly with hammers, but sound by vibrating in sympathy with the vibrations of other strings. By resonating with the overtones, these strings add richness and brilliance to the sound. These sympathetic strings are added only to the high register above approximately C4. Since they do not have a damper (a mechanism that stops them from sounding), they will continue sounding even after you play a note and then release it to stop the sound of the string that was actually struck.
Adjusting the Resonant Sounds when the Keys are Pressed (String Resonance)
When the keys are pressed on an acoustic piano, the strings for keys that are already pressed also vibrate sympathetically. The function used to reproduce is called "String Resonance."
| Parameter | Value Description | |
| String Resonance | OFF, 1-127 | Increasing the value will increase the amount of effect. |
Adjusting the String Resonance Produced when a Key is Released (Key Off Reso.)
This adjusts resonances such as the key-off sound of an acoustic piano (subtle sounds that are heard when you release a key).
| Parameter | Value Description | |
| Key Off Reso. (Key Off Resonance) | OFF, 1–127 | Higher values will increase the volume of the resonances. |
Adjusting the Sound of the Hammer Strike (Hammer Noise)
This adjusts the sound of the hammer striking the string of an acoustic piano.
| Parameter | Value Description | |
| Hammer Noise | -2-0-+2 | Higher values will increase the sound of the hammer striking the string. |
Precise Modification of Chord Sonorities (Stretch Tune)
Changes the pitch using the "stretch tune" method typically used on acoustic pianos. This makes high-range sounds slightly higher in pitch, and low-range sounds slightly lower in pitch.
| Parameter | Value Description | |
| Stretch Tune | OFF | No stretch tune. |
| ON This is | the standard tuning curve. | |
Changing the Key Touch (Key Touch/Ofst)
Use "Key Touch" to adjust the touch sensitivity of the keyboard.
You can use the "Key Touch Offset" setting to adjust the sensitivity in greater detail.

text_image
#Key Touch MEDIUM Offset. Q Key Touch value Offset value| Parameter | Value Description | |
| Key Touch | SUPER LIGHT | An even lighter setting than LIGHT. |
| LIGHT | This sets the keyboard to a light touch. You can achieve fortissimo (ff) play with a less forceful touch than usual, so the keyboard feels lighter. This setting makes it easy to play, even for children. | |
| MEDIUM | This sets the keyboard to the standard touch. You can play with the most natural touch. This is the closest to the touch of an acoustic piano. | |
| HEAVY | This sets the keyboard to a heavy touch. You have to finger the keyboard more forcefully than usual in order to play fortissimo (ff), so the keyboard touch feels heavier. Dynamic fingering adds even more feeling to what you play. | |
| SUPER HEAVY | An even heavier setting than HEAVY. | |
| Ofst (Offset) | -10-0-+9 | The touch sensitivity becomes heavier as the value increases. |

When you change the Key Touch setting, the Key Touch Offset value will be set to "0."

When "ofst" setting value continues into the positive or negative direction, the Key Touch's five-step value is switched automatically in accordance with that value.
Setting a Constant Volume Level in Response to the Playing Force (Velocity)
This sets the sound to play at a fixed volume, regardless of the strength used to play the keyboard (the velocity).
| Parameter | Value Description | |
| Velocity | REAL | Volume levels and the way sounds are played change in response to the velocity. |
| 1–127 | Values for the volume and the way sounds are played remain constant. | |
Changing the Timing of Sounds in Response to the Velocity (Velo Delay Sens)
This sets the interval from the time the key is played to when the sound is produced.
As the value is decreased, the timing of the sound is delayed more when more force is used to play the keys.
As the value is increased, the timing of the sound is delayed more when less force is used to play the keys.
| Parameter | Value |
| Velo Delay Sens (Velocity Delay Sense) | -63-0-+63 |
Changing How Volume Responds to the Velocity (Key Touch Mode)
If you choose "MODE 2," the volume will change more smoothly in response to your keyboard playing dynamics (velocity).
| Parameter | Value |
| Key Touch Mode | MODE1, MODE2 |
The process of changing Tone parameters to create the tones you like, and changing the settings for various functions is known as "editing." When the [EDIT] button is pressed and the indicator is lit, the RD-300GX switches to "Edit mode."
You can save edited settings to Setups.
Edited settings are discarded when the RD-300GX's power is turned off, so be sure that any settings you want to keep are saved to a Setup (p. 51).
However, the System settings can be saved in the edit screen. Therefore, no changes to the settings are lost, even when the power is turned off.

Making System Settings (System)
Functions that affect the RD-300GX's overall operating environment are called "System functions."
Tuning to Other Instrument's Pitches (Master Tune)
For a cleaner ensemble sound while performing with one or more other instruments, ensure that each instrument's basic pitch is in tune with that of the other instruments. In general, the tuning of an instrument is indicated by the pitch in Hertz (Hz) of the middle "A" note.
| Parameter | Value |
| Master Tune | 415.3–440.0–466.2 |
Adjusting the Volume (Master Volume)
Adjusts the volume of the entire RD-300GX.
| Parameter | Value |
| Master Volume | 0–127 |
Using a Control Pedal to Switch Setups (SETUP Pedal Sft)
You can use a control pedal connected to the CONTROL PEDAL jack to switch between RD-300GX Setups.
| Parameter | Value | Description |
| SETUP Pedal Sft (SETUP Pedal Shift) | OFF | The pedal will perform the function assigned in “Control Pedal Function” (p. 68) of the “COMMON” menu. |
| ON | Each time you press the pedal, the Setup will be switched in ascending order.* If you choose this setting, the function assigned in “Control Pedal Function” of the “COMMON” menu will be disabled. |
Using Program Change Messages to Switch Setups (SETUP Ctrl Ch.)
You can switch the RD-300GX's Setups with MIDI messages from an external MIDI device.
Set the MIDI Receive channel for receiving the MIDI messages (Program Changes) from the external MIDI device to be used for switching Setups.
When not switching Setups from an external MIDI device, set this to OFF.
| Parameter Value | |
| SETUP Ctrl Ch.(SETUP Control Channel) | 1-16, OFF |

When the SETUP Control Channel settings are transmitted along with the part's MIDI receive channel, switching of Setups takes priority over the switching of Tones.
For more information about switching Setups, refer to "Switching Setups" (p. 80).
Making the Settings for the USB Driver (USB Driver)
If you intend to connect to a computer using the USB connector, you need to make the following setting before you make the connection.
After changing this setting, turn the power off and then on again.
| Parameter | Value Description | |
| USB Driver | ORIGINAL | Select this if you're using the USB driver on the included CD-ROM (Audio Key Utility 2), or a USB driver you downloaded from the Roland website. |
| GENERIC | Choose this if you want to use the standard USB driver that was included with your computer. | |

Select the "ORIGINAL" setting if transmission and reception of MIDI data using the standard USB driver included with your computer is too slow.
Changing the USB Memory Setting (USB Memory Mode)
In some cases, when USB memory is connected to the USB MEMORY connector, it may take longer for data to be loaded, or data may fail to be loaded successfully. If this occurs, you may be able to solve the problem by changing the USB memory setting.
After changing this setting, turn the power off and then on again.
| Parameter | Value |
| USB Memory Mode | MODE1, MODE2 |
Switching the Pedal's Polarity (Damper Polarity/Control Polarity)
Switch the polarity of pedals connected to the RD-300GX.
This can be set individually for each of the Pedal jacks on the rear panel (DAMPER, CONTROL).
On some pedals, the electrical signal output by the pedal when it is pressed or released is the opposite of other pedals. If your pedal has an effect opposite of what you expect, set this parameter to REVERSE.
If you are using a Roland pedal (that has no polarity switch), set this parameter to STANDARD.
| Parameter | Value |
| Damper Polarity | STANDARD, REVERSE |
| Control Polarity |
Selecting the Indicator Mode (Indicator Mode)
This specifies how the indicators will appear when off.
| Parameter | Value Description | |
| Indicator Mode | NORMAL | The indicator will be lit if a function is on, and will be extinguished if it is off. |
| DIMLY | The indicator will be dimly lit when the function is off. This will help you find the location of the buttons even on a dimly lit stage. | |
Selecting the Number of Parts (Part Mode)
This selects the number of parts for the RD-300GX.
When set to "16PART+PERF," the performance on the keyboard is not affected by MIDI messages from the MIDI IN connector or song data played by the RD-300GX. This is useful when you want to perform on the keyboard while playing song data with the RD-300GX.
If you select "16PART," the keyboard part you yourself play can use the same part as the song data, meaning that you can specify program changes or bank selections within the song data so that the tone of the keyboard part will be switched automatically.
| Parameter | Value |
| Part Mode | 16PART, 16PART+PERF (Performance) |
Setting the Tuning Method (Temperament)
This sets the tuning.
Most modern songs are composed and played with the assumption that equal temperament will be used, but when classical music was composed, there were a wide variety of other tuning systems in existence. Playing a composition with its original tuning lets you enjoy the sonorities of the chords that the composer originally intended.
| Parameter | Value Description | |
| Tempera-ment | EQUAL | This tuning divides an octave into 12 equal parts. Every interval produces about the same amount of slight dissonance. |
| JUST(MAJOR) | This scale eliminates dissonance in fifths and thirds. It is unsuited to playing melodies and cannot be transposed, but is capable of beautiful sonorities. | |
| JUST(MINOR) | The scales of the major and minor just intonations are different. You can get the same effect with the minor scale as with the major scale. | |
| Parameter | Value Description | |
| Tempera-ment | PYTHAGOREAN | This scale devised by the philosopher Pythagoras eliminates dissonance in fourths and fifths. Dissonance is produced by third-interval chords, but melodies are euphonious. |
| KIRNBERGER | This scale is a modification of the meantone and just intonations that permits greater freedom in transposition to other keys. Performances are possible in all keys (III). | |
| MEAN TONE | This scale makes some compromises in just intonation, enabling transposition to other keys. | |
| WERCKMEISTER | This is a combination of the mean tone and Pythagorean scales. Performances are possible in all keys (first technique, III). | |
| ARABIC | This scale is suitable for Arabic music. | |
Selecting the Keynote (Temperament Key)
When playing with tuning other than equal temperament, you need to specify the keynote for tuning the song to be performed (that is, the note that corresponds to C for a major key or to A for a minor key). If you choose an equal temperament, there's no need to select a keynote.
| Parameter | Value |
| Temperament Key | C, C#, D, Eb, E, F, F#, G, G#, A, Bb, B |

When performing in ensemble with other instruments, be aware that depending on the key, there may be some shifting of the pitch. Tune the RD-300GX to the fundamental pitch of the other instruments.
Switching Between Reception of GM/GM2 System On and GS Reset (Rx GM Sys ON, Rx GS Reset)
Specifies whether General MIDI System On, General MIDI 2 System On, or GS Reset messages from external MIDI devices will be received (ON) or not (OFF).
| Parameter | Value |
| Rx. GM Sys ON(Rx GM/GM2 System ON) | ON, OFF |
| Rx. GS Reset |
Adjusting the Volume of Audio File Playback (Audio Volume)
This adjusts the volume of audio file playback (p. 40) and of the Audio Key function (p. 42).
| Parameter Value | |
| Audio Volume | 0–127 |
Having Song Playback Stop when You Press a ONE TOUCH Button (Song Stop Mode)
This specifies whether the song will stop when you press the ONE TOUCH [PIANO] button while a song is playing.
| Parameter | Value Description | |
| Song Stop Mode | ON | If you press a ONE TOUCH button while a song is playing, the song will stop playing. |
| OFF | Even if you press a ONE TOUCH button while a song is playing, the song will not stop playing. | |
Setting the Keyboard Touch (Key Touch)
You can make advanced settings for the touch used for the keys.

Setup-Related Settings (Common)
Setting the Zone to which Multi Effects are Added (MFX Zone)
This specifies the Zone to which the multi-effect will be applied when you're playing in Dual mode (p. 28) or Split mode (p. 29).
| Parameter | Value Description | |
| MFX Zone | UPPER 1 | The effect will be applied to the UPPER 1 Zone. |
| UPPER 2 | The effect will be applied to the UPPER 2 Zone. | |
| LOWER | The effect will be applied to the LOWER Zone. | |

The effect will be applied to Zones that use the same effect as this Zone.
Changing the Pedal Function (Ctrl Pedal Func)
This sets the function of the pedal switch or expression pedal (such as the optional EV-5/7) connected to the CONTROL jack on the rear panel.

Tone Settings (Tone Parameter)
You can make more detailed settings to the Tones assigned to each of the Zones.

Press the ZONE SELECT button to select the Zone to be set.
Changing Tone Elements (Attack Time/Release Time/Cutoff Freq/Resonance/Decay Time)
You can make changes in tones by adjusting the settings of the following five elements.
Attack Time: The time it takes after the key is pressed for a sound to reach full volume.
Release Time: The time it takes after the key is released for a sound to become inaudible.
Cutoff Freq: Adjusts how much the filter is opened.
Resonance: This boosts the portions in the region around the cutoff frequency, lending a particular quality to the sound. Excessively high settings can produce oscillation, causing the sound to distort.
Decay Time: The time it is to take following the attack for the volume to decrease.

Making abrupt changes in the settings values may cause the sound to become distorted or overly loud. Carefully monitor volume levels while making the settings.
| Parameter | Value Description |
| Attack Time | Higher values produce a milder attack; lower values produce a sharper attack. |
| Release Time | Higher values produce longer decay; set lower values for a clear-cut sound. |
| Cutoff Freq | Higher values brighten the sound; lower values make the sound seem darker. |
| Resonance | Higher value makes the special quality of the sound stronger; lower value reduce these characteristics. |
| Decay Time | The time it takes for the volume to fall increases as the value is raised; lowering the value decreases the decay time. |

The effect may not be apparent with some Tones, even when the value is changed.

You can perform with each Zone transposed to a different pitch.
When multiple Tones are playing, you can create a richer sound by setting the two Tones to different octaves. Also, if the keyboard mode is set to Split and you are playing a bass Tone in the lower Zone, you can use the Transpose function to play the bass at a lower pitch.
| Parameter | Value |
| Transpose | -48-0-+48 |

You can also set the same degree of transposition for all parts with the [TRANSPOSE] button. For details, refer to "Transposing the Key of the Keyboard ([TRANSPOSE] Button)" (p. 32).
Setting the Pan (Pan)
Sets the panning (localizes sound image) for each of the Zones.
The Pan setting localizes the sound image of each Zone when the output is in stereo. With an increase in the value for L, more of the sound will be heard as coming from the left side. Similarly, more of the sound will originate at the right if the value of R is increased. When set to 0, the sound is heard as coming from the center.
| Parameter | Value |
| Pan | L64-0-R63 |

Use the following procedure when recording to an external sequencer.
1. Turn on the external sequencer's Thru function.
For details, refer to the following section "About Local Switch."
Refer to your sequencer owner's manual for instructions on how to carry out this procedure.
2. Select the Setup for the performance to be recorded.
For instructions on selecting the Setup, refer to p. 50.
3. Set the Rec Mode and the Local Control.
Use the procedure described in the previous section "Settings for Recording" to make the following settings.
Rec Mode: ON
Local Control: OFF
4. Begin recording with the external sequencer.
5. Bulk Dump the Setup.
Using the Utility "Bulk Dump" in Edit mode, transmit the contents of the selected Setup to the external sequencer. For instructions on carrying out this operation, refer to "Transferring the RD-300GX's Settings to an External MIDI Device (Bulk Dump)" (p. 77).
6. Perform on the RD-300GX.
7. When the performance is finished, stop recording with the external sequencer.
Recording is now complete.
You can then listen to the recorded performance by playing it back on the external sequencer.
NOTE
Set "Part Mode" to "16PART" in Edit mode when you use the Multi-Effect settings. (p. 66)
Exiting Rec Mode
When Rec Mode is set to ON, you cannot change the External settings. When you have finished recording the performance, use the procedure described in the previous section "Settings for Recording" to set Rec Mode to OFF.
NOTE
The Rec Mode and Local Control settings cannot be saved. The settings automatically switch to "Rec Mode: OFF, Local Control: ON" when the power is turned on.
About the Local Switch
The switch that connects and disconnects the MIDI connection between the keyboard controller section and the sound generator section (p. 22) is called the Local switch. Since essential information describing what is being played on the keyboard won't reach the sound generator if the Local switch is set to OFF, the Local switch should normally be left ON. However, if while performing you want to send that performance data to an external sequencer as MIDI messages to be recorded, you then perform with the externally connected MIDI sequencer set to MIDI Thru (whereby data received from MIDI IN is then output from the MIDI OUT with no changes made to the data).

style F fill:#ffc,stroke:#333
In this case, the data sent over two paths, i.e., the data sent directly from the keyboard controller section and the data sent from the keyboard controller section via the external sequencer, ends up being sent to the sound generator section simultaneously. Thus, for example, even when you play a "C" key only once, the note "C" cannot be sounded correctly, as the sound is played by the sound generator section twice.

| Is the power to all devices turned on? — | ||
| Is the MIDI cable connected and plugged in correctly? — | ||
| No Sound From the Left Side | Is V-LINK switched on?When V-LINK is switched on, the twelve keys at the left end of the keyboard are used to control images, and no sounds are played with these keys. | p. 82 |
| No Sound in a Specific Range | With certain Tones, for example Rhythm Sets, bass Tones, Timpani, and other Tones will not sound if a portion of the Tone falls outside the recommended range. | — |
| Not All Sounds Are Played | The RD-300GX has a maximum polyphony of 128 voices. When playing together with a song or Rhythm along with heavy use of the damper pedal, the performance data may exceed the number of available voices, and as a result, some notes or sounds played on the keyboard may not sound. | — |
| Not all keyboard performance data could be processed | Could you be playing back an MP3 file, or changing the playback tempo of an audio file?The following measures may solve the problem.Use WAV/AIFF format data rather than MP3 format dataReturn the song tempo to its original setting (to 0%) | p. 41 |

| Could the Effect Level be set to 0? p. 47 | ||
| On the RD-300GX, only one type of multi-effect can be used at a time. For this reason, there’s a “MFX Zone” setting that lets you choose the Zone to which the multi-effect is to be applied. Be aware that if you’re playing more than one Zone simultaneously, there will be a Zone to which the multi-effect is not applied. | p. 68 | |
| Reverb Remains Even After Reverb is Lifted | As the RD-300GX piano sounds faithfully reproduce the depth and reverberation of actual acoustic pianos, reverberation may still be audible even after the reverb effect is removed from sounds. | — |
| Sound Suddenly Changes at Key in Upper Octaves | With the acoustic piano settings, sounds in the upper 1 1/2-octave range are extended to the end regardless of the damper pedal actions. The tone is also different in this range. Roland’s pianos faithfully reproduce the sonic qualities of acoustic pianos. Furthermore, you can use the instrument’s Key Transpose setting to change that range over which the damper pedal has no effect. | — |
| Sounds Come From Left or Right Each Time Key is Pressed (Panned) | In some Tones, the settings are such that sounds randomly play from the left or right side (are panned) each time the keys are pressed. These settings cannot be changed. | — |
| Sound is Distorted | Sounds can be distorted due to master volume, equalizer, multi-effect, and Part volume settings.Adjust the ZONE LEVEL sliders or “Master Volume” setting in the Edit mode. | p. 31, p. 57,p. 64 |
| Is a distortion-type effect being applied to the sound? p. 48 | ||
| Pitch is Odd | Depending on the Tone selected, pitches played in certain registers will be changed and played at other pitches. | — |

| Sound Keeps Playing When Key is Pressed | Is the hold pedal polarity reversed?Check the System Damper Pedal Polarity settings in Edit mode. | p. 65 |
| Song Data Not Played Back Correctly | Is the Receive GM/GM2 System On Switch set to ON?Set the System Rx GM System On or System Rx GM2 System On to ON in Edit mode. | p. 67 |
| Are you playing back GS Format song data?Once the RD-300GX receives a GS Reset message, it then is enabled for GS Format. This permits playback of music files bearing the GS logo (GS music files). However, data created exclusively for the Sound Canvas Series may not play back properly on the RD-300GX. | — | |
| Is the audio file in a format supported by the RD-300GX?Audio file of the following format be played back.WAV/AIFFSampling Rate: 44.1 kHzBit rate: 16 bitMP3Format: MPEG-1 audio layer 3Sampling Rate: 44.1 kHzBit rate: 32/40/48/56/64/80/96/112/128/160/192/224/256/320 kbps, VBR (Variable Bit Rate) | — | |
| Pedal Has No Effect, or Effect "Sticks" | Is the pedal connected correctly?Connect the pedal securely to the PEDAL jack. | p. 18 |
| Are you using a pedal made by another manufacturer?Use the pedal included with the RD-300GX or an optional DP Series or similar pedal. | — | |
| Unplugging a pedal cord from the unit while the power is on may cause the pedal's effect to be applied nonstop.Be sure to switch off the power to the unit before attempting to disconnect or connect a pedal cord. | p. 19 | |
| When Setup Pedal Shift is set to ON and the pedal is being used as a dedicated Setup switch, the control pedal function cannot be used. | p. 64, p. 68 | |
| High-Pitched Whine is Produced | When listening through headphones:Certain piano tones that feature vibrant, sparking sounds contain a large high-frequency component, which may make it appear that a metallic reverberation has been applied. This faithfully reproduces the characteristics of acoustic pianos, and does not indicate any malfunction. Since this reverberation becomes particularly audible when supplemented by heavy reverb, you may be able to diminish the problem by reducing the amount of reverb applied to the sound.When listening through speakers:Here, a different cause (such as resonance produced by the RD-300GX) would be suspect. Consult your Roland dealer or nearest Roland Service Center. | — |
