Making LFO Settings
This section explains the LFO setting screens.
fig.03-27_50
Waveform (LFO Waveform)
Selects the waveform of the LFO.
Value
SIN: Sine wave
TRI: Triangle wave
SAW: Sawtooth wave
SQR: Square wave
RND: Random wave
TRP: Trapezoidal wave
S&H: Sample & Hold wave (one time per cycle, LFO value is
changed)
CHAOS: Chaos wave
“LFO” in the lower right of the screen shows a wave graphic that
corresponds to the current settings.
Offset (LFO Offset)
Raises or lowers the LFO waveform relative to the central value.
Positive (+) settings will move the waveform so that modulation will
occur from the central value upward. Negative (-) settings will move
the waveform so that modulation will occur from the central value
downward.
Value: -100, -50, 0, +50, +100
Key Sync (LFO Key Sync Switch)
This specifies whether the LFO cycle will be synchronized to begin
when the key is pressed (ON) or not (OFF).
Value: OFF, ON
Delay Time (LFO Delay Time)
Delay Time (LFO Delay Time) specifies the time elapsed before the
LFO effect is applied (the effect continues) after the key is pressed (or
released).
Value: 0–127
After referring to “How to Apply the LFO” (p. 49), change the
setting until the desired effect is achieved.
Rate (LFO Rate) ★◆
Adjusts the modulation rate, or speed, of the LFO.
Value: 0–127, Note
LFO Rate sets the beat length for the synchronized tempo when the
tempo that specifies the LFO cycle (Patch Tempo) is synchronized
with the tempo set in a external sequencer.
(Example)
For a tempo of 120 (120 quarter notes occur in 1 minute (60 seconds))
This setting will be ignored if the Waveform parameter is set to
“CHAOS.”
“LFO” in the lower right of the screen shows a diagram of the
wave cycle that corresponds to the current settings.
Fade Mode (LFO Fade Mode)
Specifies how the LFO will be applied.
Value: ON <<, ON >>, OFF <<, OFF >>
After referring to “How to Apply the LFO” (p. 49), change the
setting until the desired effect is achieved.
Fade Time (LFO Fade Time)
Specifies the time over which the LFO amplitude will reach the
maximum (minimum).
Value: 0–127
After referring to “How to Apply the LFO” (p. 49), change the
setting until the desired effect is achieved.
How to Apply the LFO
Apply the LFO gradually after the key is
pressed
fig.LFO-1.e
Fade Mode: ON <
Fade Time: The time over which the LFO amplitude will reach the
maximum after the Delay Time has elapsed.
Delay Time: The time from when the keyboard is played until the
LFO begins to be applied.
Setting Delay time
(half note)
1 second (60 / 60 =1 (second))
(quarter note)
0.5 seconds (60 / 120= 0.5 (seconds))
(eighth note)
0.25 seconds (60 / 240= 0.25 (seconds))
Note on
high (more)
low (less)
