LFO
An LFO (Low Frequency Oscillator) applies cyclic change to the sound.
There are two LFOs for each tone (LFO1/LFO2), and you can use them
to cyclically modulate the pitch, cuto frequency, or volume to produce
modulation eects such as vibrato, wah, or tremolo. Both LFOs have the
same parameters.

LFO waveform
SIN: Sine wave
TRI: Triangle wave
SAW-UP: Sawtooth wave
SAW-DW: Sawtooth wave (negative polarity)
SQR: Square wave
RND: Random wave
BEND-UP: A waveform that rises and then holds at the
reference level when it is reached
BEND-DW: A waveform that falls and then holds at
the reference level when it is reached
TRP: Trapezoidal wave
S&H: Sample and Hold wave (the LFO value changes
once each cycle)
CHS: Chaos wave
VSIN: A modied sine wave. The amplitude of the sine
wave changes randomly once every cycle.
STEP: A waveform that is created by the LFO Step
1–16 settings. It produces stepped change in a xed
pattern.
* For some tones, “BEND-UP” or “BEND-DW” might not
produce an eect.
LFO Rate 0–127
LFO cycle speed
* This setting has no eect if WAVEFORM is set to “CHS.”
LFO Delay
Time
0–127
Time from when you press (release) the key until the
LFO eect applies (continues)
When performing with a sound such as violin or wind
instrument, it is eective to apply vibrato after the
sound has sustained for a while, rather than as soon as
the sound begins.
* Make the settings appropriate to your purpose as described
in “How to Apply the LFO” (below).

* Make the settings appropriate to your purpose as described
in “How to Apply the LFO” (below).
LFO Fade
Time
0–127
Time until the LFO amplitude reaches the maximum
(minimum)
* Make the settings appropriate to your purpose as described
in “How to Apply the LFO” (below).

Value Explanation
How to Apply the LFO
Apply the LFO gradually after the key is pressed
FADE MODE: ON-IN
DELAY TIME: Time from when the
keyboard is played until the LFO
begins to be applied
FADE TIME: Time over which the LFO
amplitude will reach the maximum
after the DELAY TIME has elapsed
Apply the LFO immediately when the key is pressed, and then gradually
begin to decrease the eect
FADE MODE: ON-OUT
DELAY TIME: Time that the LFO will
continue after the keyboard is played
FADE TIME: Time over which the LFO
amplitude will reach the minimum
after the DELAY TIME has elapsed
Apply the LFO gradually after the key is released
FADE MODE: OFF-IN
DELAY TIME: Time from when the
keyboard is released until the LFO
begins to be applied
FADE TIME: Time over which the LFO
amplitude will reach the maximum
after the DELAY TIME has elapsed
Apply the LFO from when the key is pressed until it is released, and gradually
begin to decrease the eect when the key is released
FADE MODE: OFF-OUT
DELAY TIME: Time that the LFO
will continue after the keyboard is
released
FADE TIME: Time over which the LFO
amplitude will reach the minimum
after the DELAY TIME has elapsed
KEY RANGE
These settings let you play dierent partials in dierent regions (note
numbers) of the keyboard.
Keyboard
Range
Lower
C-1–UP-
PER
Species the lowest key of the keyboard range for
each partial
Keyboard
Range
Upper
LOWER–
G9
Species the highest key of the keyboard range for
each partial.
VELOCITY RANGE
These settings let you play dierent partials according to your playing
strength (velocity) on the keyboard.
Velocity
Range
Lower
1–UPPER
Species the lowest playing strength that will sound
the partial.
Set this if you want to play dierent partials according
to your playing strength.
Velocity

Upper
LOW-
ER–127
Species the highest playing strength that will sound
the partial.
Set this if you want to play dierent partials according
to your playing strength.
Deleting a User Tone
1. In the Tone section, press the [User] button.
The User Tone list appears.
2. Use the direct buttons to select the tone that you want
to delete.
3. Press the [Option] button.
The UST Option screen appears.
4. Use the direct buttons to select “Delete.”
A conrmation message appears.
5. Use the function buttons to select “YES.”
