way down?

Are all connections properly made?

•  When using the RD-300SX as a stand-

alone instrument, be sure to connect 

with audio cables or use headphones 

Are sounds audible with headphones 

connected? 

•  If sounds are audible through 

headphones, it may indicate that there 

is a short in an audio cable or some sort 

of amp or mixer problem. Check the 

cables and equipment once again.

Is a zone level turned off with the ZONE 

LEVEL sliders? (p. 24)

If the sound for a pressed key is not being 

played, is the Local Switch set to OFF? 

•   Set the Local Control to ON (p. 46).

Are the effect settings correct?

Has the volume been lowered by pedal 

operations or by MIDI messages (volume 

messages or expression messages) 

received from an external MIDI device?

Specific Zone

 

Is the zone’s volume level turned down? 

•  Check the ZONE LEVEL sliders (p. 24).

 

No Sound From the 

Connected MIDI 

Device

 

Is the device enabled to transmit MIDI 

messages? 

•  Set [MIDI TX] to ON (p. 47). MIDI 

messages cannot be transmitted if 

[MIDI TX] is set to OFF.

 

No Sound From the 

Connected MIDI

Is the RD-300SX’s keyboard controller 

section MIDI Transmit channel matched 

to the connected MIDI device’s MIDI 

Receive channel? 

•  Make the Ch settings screen (p. 47).

 

No Sound (With a 

MIDI Device 

Connected)

 

Is the power to all devices turned on?

Is the MIDI cable connected and plugged 

in correctly?

Does the MIDI channel match the 

connected instrument? (p. 47)

 

No Sound From the 

Left Side

 

Is V-LINK switched on (p. 51)? 

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.

 

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-300SX 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.

 

Tones Are Altered

 

Did you call up a Setup? 

•  When a Setup is called up, the current 

Tone, effect, and other settings are 

disabled, and the selected Setup goes 

into effect (p. 34). Save the required 

Did you press ONE TOUCH [PIANO]? 

•  When ONE TOUCH [PIANO] is 

pressed, the current Tone, effect, and 

other settings are disabled, and settings 

for use in piano performances go into 

effect (p. 18). Save the required settings 

When a mono connection is used, the 

tone quality of some sounds may change, 

depending on the type of sound and the 

register in which it is used.

To enjoy the best quality when listening 

to such sounds, we recommend 

connecting in stereo.
