Power Not Coming On
 
Is the power cord properly connected?
 
No Sound
 
Is the volume level of the RD-300GX or connected device turned all the way down?
Are all connections properly made?
•  When using the RD-300GX 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?
Is the Part setting set to OFF?
If the sound for a pressed key is not being played, is the Local Control set to OFF? 
•  Set the Local Control to ON.
Are the effect settings correct?
 
•  Check the ON/OFF settings for the [MULTI EFFECTS] button, MFX Zone and level settings.
 
Has the volume been lowered by pedal operations or by MIDI messages (volume messages 
or expression messages) received from an external MIDI device?
 
No Sound for Specific 
Zone
 
Is the Zone’s volume level turned down? 
•  Check the ZONE LEVEL sliders.
 
No Sound From the 
Connected MIDI Device
 
Is the device enabled to transmit MIDI messages? 
•  Set the [EXTERNAL/INTERNAL] button to “EXTERNAL.” MIDI messages cannot be 
transmitted if the [EXTERNAL/INTERNAL] button is set to “INTERNAL.”
Is the RD-300GX’s keyboard controller section MIDI Transmit channel matched to the 
connected MIDI device’s MIDI Receive channel? 
•  Make the Ch settings.
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.
 
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 data
•  Return the song tempo to its original setting (to 0%)
