Wave
This parameter selects the LFO waveform. The numbers that
appear at the right of some of the LFO waveforms indicate
the phase at which the waveform will begin.
Frequency
Set the LFO frequency. A setting of 99 is the fastest.
00…99 Frequency rate.
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 operate 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 wave-
form. For example, with a setting of 0 as shown in the follow-
ing 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
-99…+99 Offset value.
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 amplitude. 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):
00…99 Fade rate.
Frequency MIDI/Tempo Sync
MIDI/Tempo Sync
This parameter enables/disables the LFO synchronization
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 “Frequency”
(see page 14-17) and “Frequency modulation”
(see page 14-17) 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 (quar-
ter 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 Modulation
Source) list” on page 14-19). 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 frequency 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 (+) val-
ues 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.

Random1 (S/H):
Conventional sample & hold (S/H) in which the
level changes randomly at fixed intervals of
time
Random2 (S/H):
Both the levels and the time intervals will
change randomly.
Random3 (S/H):
The maximum level and minimum level will
alternate at random intervals of time (i.e., a
square wave with random period).
Random4 (Vector)
Random5 (Vector)

These types cause Random 1–3 to change

instability of acoustic instruments etc.
