Check/Solution
Is the V-Piano Grand's power cord properly plugged into a power outlet as well as connected to the V-Piano Grand?
Could panel lock be active?
• Disengage the panel lock.
Is the volume turned all the way down?
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.
Could headphones be connected?
Could headphones or a headphone plug adaptor have been left inserted in the Phones jack?
• No sound will be produced from the speakers if headphones or an adaptor plug is inserted in the Phones
jack.
Is the Local Switch set to OFF?
• Set the Local Switch to ON.
Could the volume have been lowered by pedal operations or by MIDI messages (volume messages and expression
messages) received from an external MIDI device or from song data?
• Raise the Master Volume.
• Try switching Tones.
Is Visual Control switched on?
• If you set the Visual Control setting Local ON/OFF to the Local On setting, you'll be able to play sounds from
the keyboard even if Visual Control is on.
Does the V-Piano Grand's MIDI transmit channel match the MIDI receive channel of the connected MIDI device?
• Set the MIDI transmit channel.
Did you call up a Setup?
• When a Setup is called up, the current Tone and other settings are disabled, and the selected Setup goes
into effect. Resave required settings to a Setup.
If you're using a monaural connection, the tonal character may change depending on the Tone or the register.
• In order to enjoy the V-Piano Grand's sound to its fullest potential, we recommend a stereo connection.
• If you're using a monaural connection, set Line Out Mode to MONO.
Some equalizer settings may cause the sound to distort. Try adjusting the equalizer's Input Gain.
Depending on the Tone selected, pitches played in certain registers will be changed and played at other pitches.
Have settings for Stretch Tune been made?
Has the V-Piano Grand gone out of tune? Check the following settings.
• Master Tune settings
• Temperament settings
Have you set Transpose?
Could you be using a connection cable that contains a resistor?
Use a connection cable that does not contain a resistor.
The V-Piano Grand uses a hammer action keyboard in order to simulate an acoustic piano's playing touch as
realistically as possible. The thump of the hammers will be heard when you play the keyboard; this is not a
malfunction.
If vibration transmitted to the floor or walls is a concern, you may be able to minimize the vibration by moving the
piano away from the wall, or by laying down a commercially available anti-vibration mat designed for use with
pianos.
Is the audio data playable?
• Make sure that the audio data can be played by the V-Piano Grand.
Since the V-Piano Grand uses a liquid crystal screen, it may happen that no text or graphics appear in the screen if
the temperature is below zero degrees Celsius (32 degrees Fahrenheit).
These occur due to the nature of a liquid crystal display, and do not indicate a malfunction. They can be minimized
by adjusting the contrast of the screen.
Is the pedal connected correctly?
• Plug the cord firmly into the Pedal connector.
