Tone Parameters
Parameter Value Explanation
Waveform
Selects the waveform of the LFO.
SIN Sine wave
TRI Triangle wave
SAW-UP Sawtooth wave
SAW-DW Sawtooth wave (negative polarity)
SQR Square wave
RND Random wave
TRP Trapezoidal wave
S&H
Sample & Hold wave (one time per cycle,
LFO value is changed)
CHS Chaos wave
VSIN
Modied sine wave. The amplitude of a
sine wave is randomly varied once each
cycle.
STEP
A waveform generated by the data
specied by LFO Step 1–16.
This produces stepped change with a
xed pattern similar to a step modulator.
Rate Sync
OFF, ON
Set this “ON” if you want the LFO rate to
synchronize with the tempo.
Rate (note)
1/64T–4
Species the LFO rate in terms of a note
value.
* This is valid when the Rate Sync is “ON.”
Rate
0–1023
Species the LFO rate without regard to
the tempo.
Higher values produce a faster LFO rate
(a shorter cycle).
* This is valid when the Rate Sync is “OFF.”
Oset
-100–100
Raises or lowers the LFO waveform
relative to the central value (pitch or
cuto 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.
Rate Detune
0–127
Subtly changes the LFO cycle speed
(Rate parameter) each time you press
a key.
Higher values produce greater change.
* This is invalid when Rate is set to “note.”
Delay Time
0–1023
Species the time elapsed before the LFO
eect is applied (the eect continues)
after the key is pressed (or released).
* After referring to “How to Apply the
LFO,” change the setting until the
desired eect is achieved.
Delay Time KF
-100–+100
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 eect is applied (the eect 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 eect is applied (the eect is
continuous) to change according to the
key pressed, set this to “0.”

Fade Mode
ON-IN
Species how the LFO will be applied.
* After referring to “How to Apply the
LFO,” change the setting until the
desired eect is achieved.

Parameter Value Explanation
Fade Time
0–1023
Species the time over which the LFO
amplitude will reach the maximum
(minimum).
* After referring to “How to Apply the
LFO” (p. 46), change the setting until
the desired eect is achieved.
Key Trigger Switch
OFF, ON
Species whether the LFO cycle will be
synchronized to begin when the key is
pressed (ON) or not (OFF).
Pitch Depth
-100–100
Species how deeply the LFO will aect
pitch.
* If OSC Type (p. 39) is other than VA,
the range is limited to -63–+63.
Filter Depth
-100–100
Species how deeply the LFO will aect
the cuto frequency.
Amp Depth
-100–100
Species how deeply the LFO will aect
the volume.
Pan Depth
-63–+63
Species how deeply the LFO will aect
the pan.
MEMO
Positive (+) and negative (-) value for the
Depth parameter result in diering kinds
of change in pitch and volume.
For example, if you set the Depth
parameter to a positive (+) value for one
partial, and set another partial to the same
numerical value, but make it negative (-),
the modulation phase for the two partials
will be the reverse of each other.
This allows you to shift back and forth
between two dierent partials, or combine
it with the Pan setting to cyclically change
the location of the sound image.
Phase Position
Species the LFO’s starting phase value when Key Trigger is ON.
* This has no eect if Waveform is “RND,” “S&H,” or “CHS.”
0 1 cycle
1 1/4 cycle
2 1/2 cycle
3 3/4 cycle
Step Size 1–16
Species the length of the step change.
* This is eective if Waveform is “STEP.”
Step1–16 -72–+72
Specify the Depth value of each step.
If you want to specify this in pitch scale
degrees (100 cents), the settings are as
follows.
1 Pitch Depth: 51, Step: multiples of 6
up to one octave of change
2 Pitch Depth: 74, Step: multiples of 3
up to two octaves of change
3 Pitch Depth: 89, Step: multiples of 2
up to three octaves of change
* If OSC Type is not VA, the Pitch Depth
setting range is limited to -63–+63, so
only “1” above is possible.
Step Curve1–16 0–36
Species the type of curve at each step.
