[F1] Custom Voice Edit
4 EG RATE
l
Attack
Sets the speed of attack — i.e. how fast the sound
reaches maximum level after a key is pressed.
“0” sets the normal attack for the selected voice, minus
settings produce a slower attack, and plus settings produce
a faster attack.
l l
Decay
Sets the speed of decay portion of the envelope — i.e.
how fast the sound decays from the maximum attack level
to its normal level.
“0” sets the normal decay for the selected voice, minus
settings produce a slower decay, and plus settings produce
a faster decay.
l l
Release
Sets the speed of release — i.e. how fast the sound de-
cays after a key is released when the panel [SUSTAIN]
button is off and the sustain pedal is not pressed.
“0” sets the normal release for the selected voice, minus
settings produce a slower release decay, and plus settings
produce a faster release decay.
The attack, decay, sustain, and release parameters provided here let you
shape the volume envelope of the voice.
Use the and buttons to switch between the two display screens,
and the [-] and [+] buttons below each parameter to set the required values.
l l
Sustain
Sets the speed of sustain decay — i.e. how fast the
sound decays after a key is released when the panel [SUS-
TAIN] button is on or the sustain pedal is pressed.
“0” sets the normal sustain for the selected voice, minus
settings produce a longer sustain decay, and plus settings
produce a faster sustain decay.
Notes:
The maximum range for all parameters is from -50
through 0 to +50, although this range is more limited with
some voices. An exclamation mark (!) will appear next to the
parameter when the maximum or minimum allowable setting
for the selected voice has been reached.
The default values for the selected voice are produced by
settings of “0”. Pressing both the [-] and [+] buttons below a
parameter immediately recalls the default value (“0”).
With voices like 21 STRINGS, in which key velocity (keyboard
dynamics) controls the speed of attack, attack speed changes
in the same way even if the attack parameter is set to a minus
value.
Since PIANO 1 (00) and some other voices already have
the fastest possible attack, no sound will be produced if the
Decay parameter for such voices is set to “+50.”
The Decay parameter will have no effect on some sustain-
type voices which have no inherent decay.
Changing the EG rate parameter may have no effect on the
sound with some voices.
