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.
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.
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).
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).
LFO effect is applied (the effect continues) after the key is pressed (or
released).
Value:
0–127
After referring to
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.
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.”
“CHAOS.”
“LFO” in the lower right of the screen shows a diagram of the
wave cycle that corresponds to the current settings.
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
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).
maximum (minimum).
Value:
0–127
After referring to
setting until the desired effect is achieved.
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))
