to an AC outlet?
Check the AC cord connections.
No Sound/Volume is low
Is the power of the connected devices turned on?
Make sure that the power of your amp or mixer system 
is turned on.
Is the volume turned down?
Check the volume of the V-Synth and of the connected 
amp or mixer.
Is there sound in the headphones?
If there is sound in the headphones, it is possible that 
the connection cables are broken, or that the amp or 
mixer is malfunctioning. Check the connection cables 
and your other equipment once again.
Is the Demo Song playback selected?
Press [EXIT] to exit Demo Song playback mode (Quick 
Start; p. 8).
Is the Local Switch turned OFF?
Is the Patch level set too low?
Are the Effect settings correct?
Check the Effect settings ON or OFF, in the Effect Bal-
ance or Level (p. 50).
Are the settings for the output destination correct?
Have volume messages been received from an external 
MIDI device to lower the volume?
Check the volume.
Could the oscillator be off?
Press [OSC1] or [OSC2] to turn on the oscillator.
Could the V-Synth be set to USB communication in 
Storage mode?
The volume level of the instru-
ment connected to INPUT 
Jacks is too low.
Could you be using a connection cable that contains a 
resistor?
Use a connection cable that does not contain a resistor.
Pitch is wrong
Are the Pitch settings of the Oscillator section correct? Check the Coarse Tune/Fine Tune parameter settings 
Is the Master Tune setting correct?
Has a Pitch Bend message been received from an exter-
nal device, leaving the pitch “hanging?”
Try moving the pitch bend lever of the connected MIDI 
keyboard.
When you play the keyboard, 
notes do not stop
Is the pedal polarity of the Hold Pedal reversed?
Sound is distorted
Is an effect which distorts the sound being applied?
Has the Patch level been turned up?
Effects do not apply
[MFX], [CHO], or [REV] effect switches may have been 
turned off.
Turn them on.
Are the various effect settings correct?
If the send level of each effect is set to 0, the effect will 
not be applied. Check the settings (p. 50).
Even with send levels to each effect set at 0, effects are 
not applied if the MFX Master Level, the Chorus Mas-
ter Level, or the Reverb Master Level is set to 0. Check 
each setting (p. 50).
If Output Assign is set to other than “MULTI,” the 
MFX sound will not be output (p. 50).
Oscillator Type has been to 
“EXT IN,” but no sound is 
heard when audio is input 
through the INPUT jacks
If the oscillator is set to external input (EXT IN), you 
will not hear sound unless you play the keyboard.
Try playing the keyboard.
No sound from connected 
MIDI device
Is the instrument set to transmit MIDI messages?
Does the MIDI transmit channel for the V-Synth match 
the MIDI receive channel for the connected MIDI de-
vice?
