The AMPLITUDE ENVELOPE LCD [▲/▼]
controls are used to set the amplitude envelope
RATE and LEVEL parameters. Use the RATE or
LEVEL LCD button to select the corresponding
group of parameters.
RATE
These parameters set the rate of output level
variation. Higher values produce faster variation.
A
TTACK : Sets the speed of variation from key-on to
the maximum attack level.
D ECAY 1, D ECAY 2, D ECAY 3: Set the speed of varia-
tion between the maximum attack level and the
levels set by the
LEVEL D ECAY 1, D ECAY 2, and
D ECAY 3 parameters, respectively.
R ELEASE 1: Sets the rate of variation from the level at
key-release to level 0 when SUSTAIN is off.
S USTAIN : Sets the rate of variation from the level at
key-release to level 0 when SUSTAIN is on.
LEVEL
These parameters sets the envelope output level.
Higher values produce higher output.
The
A TTACK level is fixed at maximum and cannot be
changed.
D
ECAY 1, D ECAY 2, D ECAY 3: Set the levels after
D ECAY 1, D ECAY 2, and D ECAY 3 variation.
