VRM (Virtual Resonance Modeling)
On an actual acoustic piano, if you press the damper pedal and play a key, not only does the string of the pressed key vibrate, it
also causes other strings and the soundboard to vibrate, with each influencing the rest, creating a rich and brilliant resonance that
sustains and expands. The VRM technology featured in this instrument reproduces the complicated interaction between both
string and soundboard resonance, and make the sound more like that of a real acoustic piano. Since resonance instantaneously
occurs depending on the action of the keys and pedal, you can expressively vary the sound by changing the timing of your
pressing the keys, and the timing and depth of your pressing the pedal.
Grand Expression Modeling
On an actual acoustic piano, subtle changes in the sound can be produced by changing your playing touch from when you press
a key to when you release it. For example, when you press a key all the way to its bottom, the key hits the keybed underneath and
the noise reaches the strings, changing the sound slightly. Furthermore, the tone when the damper is lowered onto strings to mute
the sound is changed by how quickly you release the key. The Grand Expression Modeling technology recreates these subtle
changes in the sound that respond to your touch. This allows you to add accents by playing strongly or add resonance by playing
softly to produce superbly expressive sound. A crisp tone can be heard when playing staccato as well as a lingering sound
produced when releasing the keys slowly.
Problem
Possible Cause and Solution
Power suddenly and unexpectedly
turns off.
This is normal and the Auto Power Off function may have been activated (page 12).
If desired, disable the Auto Power Off function.
The instrument does not turn on.
The plugs are not properly connected. Make sure that the DC plug is securely inserted
into the DC IN jack on the instrument, and that the AC plug is securely inserted to the AC
outlet (page 12).
A click or pop is heard when the
power is turned on or off.
This is normal when electrical current is being applied to the instrument.
Noise is heard from the speakers
or headphones.
The noise may be due to interference caused by the use of a mobile phone in close
proximity to this instrument. Turn off the mobile phone, or move it further away from this
instrument.
Metronome or Song goes out of
tempo slightly when you play the
keyboard.
This occurs infrequently when Grand Expression Modeling is set to “Dynamic.” If this
happens, set Grand Expression Modeling to “Static” (page 15).
The overall volume is low, or no
sound is heard.
The Master Volume is set too low. Set it to an appropriate level using the [MASTER
VOLUME] knob (page 10).
Make sure a pair of headphones or conversion adaptor is not connected to the
[PHONES] jack (page 13).
The Speaker setting is “Off.” Set the Speaker to “Normal” or “On” (page 13).
Make sure that Local Control is On. For details, refer to the “MIDI Reference” (page 9).
Pedals do not function.
The pedal cord may not be securely connected to the [TO PEDAL] jack. Be sure to
insert the pedal cord all the way until the metal part of the cord plug disappears from
view (page 32).
The damper pedal does not
function as expected.
The damper pedal was pressed when the power was turned on. This is not a
malfunction; release the pedal and press it again to reset the function.
