Explanation
Specify this if you want keyboard dynamics to
affect the AMP envelope's Time 1. If you want
Time 1 to be speeded up for strongly played
notes, set this parameter to a positive (+)
value. If you want it to be slowed down, set
this to a negative (-) value.
Specify this if you want key release velocity to
affect the AMP envelope's Time 4. If you want
Time 4 to be speeded up for quickly released
notes, set this parameter to a positive (+)
value. If you want it to be slowed down, set
this to a negative (-) value.
If this is ON, the amp envelope is cyclically
retriggered by LFO1.
* This is effective when Envelope Mode is
SUSTAIN.
Specify the AMP envelope times (Time 1–
Time 4). Higher settings lengthen the time
until the next volume level is reached. (For
example, Time 2 is the time over which Level
1 will change to Level 2.)
* If ADSR Envelope Switch is ON, the Time 2 has
no effect.
Specify the AMP envelope levels (Level 1–
Level 3).
These specify the amount of change at
each point relative to the reference volume
(the partial level value specified in the Amp
screen).

* If ADSR Envelope Switch is ON, only Level 3
(Sustain) has an effect.
Specify this if you want keyboard position
to affect the AMP envelope's times (Time 2–
Time 4). Relative to the AMP envelope times
at the C4 key (middle C), positive (+) values
cause the times to shorten as you play higher
on the keyboard, and negative (-) values
cause the times to lengthen. Higher values
will produce greater change.

Explanation

Square wave
Random wave
Trapezoidal wave
Sample & Hold wave (one time per cycle, LFO
value is changed)
Chaos wave
Modified sine wave. The amplitude of a sine
wave is randomly varied once each cycle.
A waveform generated by the data specified
by LFO Step 1–16. This produces stepped
change with a fixed pattern similar to a step
modulator.
Set this ON if you want the LFO rate to
synchronize with the tempo.
This is effective if Rate Sync is ON.
Specifies the LFO rate in terms of a note
value.
This is effective if Rate Sync is OFF.
Specifies the LFO rate without regard to the
tempo. Higher values produce a faster LFO
rate (a shorter cycle).
Raises or lowers the LFO waveform relative to
the central value (pitch or cutoff frequency).
Positive (+) value will move the waveform so
that modulation will occur from the central
value upward. Negative (-) value will move
the waveform so that modulation will occur
from the central value downward.
Subtly changes the LFO cycle speed (Rate
parameter) each time you press a key. Higher
values produce greater change.
This parameter is invalid when Rate is set to
"note. "
Specifies the time elapsed before the LFO
effect is applied (the effect continues) after
the key is pressed (or released).
* After referring to "How to Apply the LFO" (p.
72), change the setting until the desired effect
is achieved.
Adjusts the value for the Delay Time
parameter depending on the key position,
relative to the C4 key (center C). To decrease
the time that elapses before the LFO effect
is applied (the effect is continuous) with
each higher key that is pressed in the upper
registers, select a positive (+) value; to
increase the elapsed time, select a negative
(-) value. Higher values will produce greater
change. If you do not want the elapsed time
before the LFO effect is applied (the effect is
continuous) to change according to the key
pressed, set this to "0. "
