Element Edit
From this display you can make all the time and level settings for the Amplitude EG, which determine how the
volume of the sound changes over time. These can be used to control the change in volume from the moment
a note is pressed on the keyboard to the moment the sound stops.
The full names of the available parameters are shown in the chart below, as they appear in the display.
TIME ---
LVL/SW Initial level
When the Half Damper switch is turned on, you can use the Half Damper function with an optional Foot
Controller FC3 connected to the FOOT SWITCH SUSTAIN jack.
Unlike a conventional damper pedal control which simply turns sustain on and off, the Half Damper function
lets you finely control the amount of sustain and natural decay—just as with a real acoustic piano—by using a
continuous pedal controller.
n
Please note that the SusPedal parameter (below) must be set to "FC3 (Half On)."
[UTILITY]
However, if you are controlling the Half Damper function by Control Change messages from an external MIDI device, it
is not necessary to change the SusPedal parameter.
Settings: TIME: 0 ~ 127
LVL/SW (Level/Switch): 0 ~ 127 or on/off

For details on the AEG, see page 114.
From this display you can set the Key Follow effect for Amplitude—in other words, how the volume of the
Element and its Amplitude EG respond to the particular notes (or octave range) you play.
Determines the degree to which the notes (specifically, their position or octave range) affect the volume of the
selected Element. A Center Key setting of C3 is used as the basic setting.
A positive setting will lower the output level for lower notes and raise it for higher notes. A negative setting will
have the opposite effect.
Settings: -200 ~ 0 ~+200
This indicates that the central note for Level Sensitivity above is C3. At C3, the volume (level) remains
unchanged. For other notes played, the volume varies according to the particular note and the Level Sensitivity
setting. Keep in mind that this is for display purposes only; the value cannot be changed.
Determines the degree to which the notes (specifically, their position or octave range) affect the Amplitude EG
times of the selected Element. The Center Key (next parameter) is used as the basic amplitude for this
parameter. A positive setting will cause the amplitude of lower notes to change slower and that of higher notes
to change faster. Negative values will have the opposite effect.
Settings: -64 ~ 0 ~ +63
Determines the central note or pitch for the Key Follow effect on Amplitude EG. Depending on the EG Time
Sensitivity parameter above, the further away from the Center Key the keys are played, the more the time of the
Amplitude EG deviates from the norm.
When the Center Key is played, the AEG behaves according to its actual settings. The amplitude change
characteristics for other notes will vary in proportion to the EGTime settings.
Settings: C -2 ~ G8

You can also set the Center Key directly from the keyboard, by holding down the [INFORMATION] button and pressing
the desired key.

Amplitude Scaling controls the output level (set in the [F4] AMP
positions of the notes on the keyboard. You can divide the entire keyboard by four break points, and assign
different offset values of amplitude to them respectively. Refer to the setting example on page 147.
Settings: BREAK POINT 1 ~ 4: C-2 ~ G8
Settings: OFFSET 1 ~ 4: -128 ~ 0 ~ +127

You can also set the Break Point directly from the Keyboard, by holding down the [INFORMATION] button and pressing
the desired key.
