Key Sync
This parameter specifies if the LFO is synchronized to
key strokes.
On The LFO will start each time you play a
note, and an independent LFO will oper‐
ate for each note.
Off The LFO effect that was started by the
first‐played note will continue to be
applied to each newly‐played note. (In
this case, Delay and Fade will be applied
only to the LFO when it is first started).
Offset
This parameter specifies the central value of the LFO
waveform. For example, with a setting of 0 as shown in
the following diagram, the vibrato that is applied will
be centered on the note‐on pitch. With a setting of +99,
the vibrato will only raise the pitch above the note‐on
pitch, in the way in which vibrato is applied on a guitar.
When "Wave" is set to Guitar, the modulation will
occur only in the positive (+) direction even if you set
"Offset" to 0.
Here are offset settings and pitch change produced by
vibrato

Delay
This parameter specifies the time from note‐on until
the LFO effect begins to apply. When "Key Sync" is Off,
the delay will apply only when the LFO is first started.
0...99 Delay time.
Fade In
This parameter specifies the time from when the LFO
begins to apply until it reaches the maximum ampli‐
tude. When "Key Sync." is Off, the fade will apply only
when the LFO is first started.
Here is how "Fade In" affects the LFO (when "Key
Sync" is On):

Frequency MIDI/Tempo Sync
MIDI/Tempo Sync
This parameter enables/disables the LFO synchroniza‐
tion with Sequencer 1 Tempo.
On The LFO frequency will synchronize to
the tempo (MIDI Clock) of Sequencer 1. In
this case, the values you specified for "Fre‐
quency" (see page 120) and "Frequency
modulation" (see page 121) will be
ignored.

Base Note/Times
When "MIDI/Tempo Sync" is On, these parameters set
a note length relative to " (Tempo)" and the multiple
("Times") that will be applied to it. These parameters
will determine the frequency of the LFO1. For example
if "Base Note" is (quarter note) and "Times" is 04, the
LFO will perform one cycle every four beats.
Even if you change the " (Tempo)" setting of
Sequencer 1, the LFO will always perform one cycle
every four beats.

01...16 Beats before restarting the cycle.
Frequency modulation
You can use two alternate modulation sources to adjust
the speed of the LFO1 for the selected oscillator.
AMS1(F) (Alternate Modulation Source1)
Selects the source that will adjust the frequency of the
selected oscillator LFO1 (see "AMS (Alternate Modula‐
tion Source) list" on page 123). LFO1 can be modulated
by LFO2.
Intensity (AMS1 Intensity)
This parameter specifies the depth and direction of the
effect that "AMS1(F)" will have. When this parameter is
set to a value of 16, 33, 49, 66, 82, or 99, the LFO fre‐
quency being can be increased by a maximum of 2, 4, 8,
16, 32, or 64 times respectively (or decreased by 1/2, 1/4,
1/8, 1/16, 1/32, or 1/64 respectively).
For example, if "AMS1(F)" is Note Number, positive (+)
values of this parameter will cause the oscillator LFO to
speed up as you play higher notes. Negative (–) values
will cause the oscillator LFO to slow down as you play
higher notes. This change will be centered on the C4
note.
If "AMS1(F)" is set to JS +Y, raising the value of this
parameter will cause the oscillator LFO1 speed to
increase as the joystick is moved away from yourself.
With a setting of +99, moving the joystick all the way
away from yourself will increase the LFO speed by
approximately 64 times.
‐99...+99 Intensity value.
AMS2(F) (Alternate Modulation Source2)
Intensity (AMS2 Intensity)
Make settings for a second alternate modulation source
that will adjust the frequency of the oscillator LFO1
(see above "AMS1(F) (Alternate Modulation Source1)"
and "Intensity (AMS1 Intensity)").
