Here you can make settings for the LFO that can be used to
cyclically modulate the Pitch, Filter, and Amp of oscillators 1
and 2. There are two LFO units for each oscillator. By setting
the LFO1 or LFO2 Intensity to a negative (–) value for Pitch,
Filter, or Amp, you can invert the LFO waveform.
5–1: OSC1 LFO1
Make settings for the “OSC1 LFO1,” which is the first LFO
that can be used for oscillator 1.
5–1a: OSC1 LFO1
Waveform [Triangle 0…Random6 (Vector)]
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 [00…99]
Sets the LFO frequency. A setting of 99 is the fastest.
Offset [–99…+99]
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 “Waveform” is set to Guitar, the modulation will
occur only in the positive (+) direction even if you set “Off-
set
” to 0.
Offset settings and pitch change produced by vibrato
Key Sync. [Off, On]
On (checked): The LFO will start each time you press a key,
and an independent LFO will run for each note.
Off (unchecked):
The LFO effect that started when the first
key was pressed will also apply to subsequently-played
notes. (In this case, the delay and fade effects will apply only
to the first-started LFO.)
Fade [00…99]
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.
How “Fade” affects the LFO (when “Key Sync.” is On)
Delay [0…99]
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.
5–1b: Frequency Modulation
You can use two alternate modulation sources to adjust the
speed of the OSC1 LFO1.
AMS1 (Freq. AMS1)
[Off, (PEG, FEG, AEG, LFO2, KT, EXT)]
Selects the source that will adjust the frequency of the oscil-
lator 1 LFO1 (“AMS List”
☞p.242). OSC1 LFO1 can be mod-
ulated by OSC1 LFO2.
Intensity (AMS1 Intensity) [–99…+99]
Specifies the depth and direction of the effect that “AMS1
(Freq. AMS1)” 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 maxi-
mum 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 (Freq. AMS1)” is Note Number, pos-
itive (+) values
of this parameter will cause the oscillator 1
LFO to speed up as you play higher notes. Negative (–) val-
ues
will cause the oscillator 1 LFO to slow down as you play
higher notes. This change will be centered on the C4 note.
If “AMS1 (Freq. AMS1)” is set to JS +Y: CC#01, higher set-
tings for this parameter will cause the OSC1 LFO speed to
become proportionately faster when you move the joystick.
With a setting of +99, the LFO speed will be approximately
64 times faster when the joystick is pushed all the way away
from yourself.
AMS2 (Freq. AMS2)
[Off, (PEG, FEG, AEG, LFO2, KT, EXT)]
Intensity (AMS2 Intensity) [–99…+99]
Make settings for a second alternate modulation source that
will adjust the frequency of the oscillator 1 LFO1. (
☞“AMS1
(Freq. AMS1),” “Intensity (AMS1 Intensity)”)

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 (Vect.)
Random5 (Vect.)
Random6 (Vect.)
These types cause Random 1–3 to change
smoothly. They can be used to simulate the
instability of acoustic instruments etc.
