[TEMPO SYNC] button
This button lets you specify the LFO speed as a note value
relative to the arpeggio or phrase recorder tempo.
If you press the [TEMPO SYNC] button so it's lit, and then
turn the [RATE] knob, the LFO speed (cycle) will change in
steps of note lengths "RATE" (p. 47).
If you press the [TEMPO SYNC] button once again to
turn off its illumination, the [RATE] knob will return to its
original operation.
* The [TAP TEMPO] button (p. 23) blinks at quarter-note
intervals to indicate the tempo of the arpeggio or phrase
recorder.
[RATE] knob
This determines the speed of the LFO.
Turning the knob toward the right will make the modula-
tion faster, and turning it toward the left will make the
modulation slower.
* The indicator above the [RATE] knob blinks in synchroni-
zation with the LFO speed (cycle).
[FADE TIME] slider
This specifies the time from when the tone sounds until
the LFO reaches its maximum amplitude.
FADE TIME
[PITCH DEPTH] slider
This allows the LFO to modulate the pitch, producing a
vibrato effect.
• Moving the slider upward ("+" settings) will deepen the
modulation.
• If the slider is in the center position (0), the pitch will not
be modulated by the LFO.
• Moving the slider downward ("-" settings) will apply
modulation with an inverted LFO waveform.
[FILTER DEPTH] slider
This allows the LFO to modulate the FILTER CUTOFF (cutoff
frequency), producing a wah effect.
• Moving the slider upward ("+" settings) will deepen the
modulation.
• If the slider is in the center position (0), the cutoff
frequency will not be modulated by the LFO.
• Moving the slider downward ("-" settings) will apply
modulation with an inverted LFO waveform.
[AMP DEPTH] slider
This allows the LFO to modulate the AMP LEVEL (volume),
producing a tremolo effect.
• Moving the slider upward ("+" settings) will deepen the
modulation.
• If the slider is in the center position (0), the amp level will
not be modulated by the LFO.
• Moving the slider downward ("-" settings) will apply
modulation with an inverted LFO waveform.
PAN DEPTH
Here's how to make the PAN (stereo position) vary (Auto
Panning).
1. While holding down the [CANCEL/SHIFT] button,
move the [AMP DEPTH] slider.
• Moving the slider upward ("+" direction) will deepen the
modulation.
• If the slider is in the center position (0), there will be no
modulation.
• Moving the slider downward ("-" direction) will apply
modulation with the LFO waveform in reversed phase.
MODULATION LFO
Each tone has two LFOs: an LFO that is always applied to
the tone, and a MODULATION LFO that is used to apply
modulation when the pitch bend/modulation lever is
moved away from yourself.
1. Hold down the [CANCEL/SHIFT] button and move
the pitch bend/modulation lever away from
yourself.
The LFO SHAPE indicator will blink.
2. Edit the following parameters.
• SHAPE (p. 47)
• TEMPO SYNC (p. 47)
• RATE (p. 48)
• PITCH DEPTH (p. 48)
• FILTER DEPTH (p. 48)
• AMP DEPTH (p. 48)
• PAN DEPTH (p. 48)
LFO KEY TRIGGER and FADE TIME cannot be specified for
the MODULATION LFO.
Speed and waveform of vibrato applied by the modulation
lever
The speed and waveform of the vibrato applied when
you move the modulation lever (p. 19) away from yourself is
determined by the MODULATION LFO's SHAPE and RATE
settings.
