LFO: LFO1
Sl (Slope Time Swing)
This parameter specifies the direction of the effect that “AMS1”
will have on “Slope”. With positive (+) values of “Intensity”, set-
ting this parameter to + will allow AMS1 to lengthen the time,
and setting it to – will allow AMS1 to shorten the time. With a
setting of 0 there will be no effect.
Rl (Release Time)
This parameter specifies the direction of the effect that “AMS1”
will have on “Release”. With positive (+) values of “Intensity”,
setting this parameter to + will allow AMS1 to lengthen the time,
and setting it to – will allow AMS1 to shorten the time. With a
setting of 0 there will be no effect.
AMS2 (Alternate Modulation Source 2)
This is another alternate modulation source for the Amp EG. See
above “AMS1” parameters.
LFO: LFO1
In this and the next page you can make settings for the LFO that
can be used to cyclically modulate the Pitch, Filter, and Amp of
each oscillator. 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.
Waveform
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.
Offset
This parameter specifies the central value of the LFO waveform.
For example, with a setting of 0 as shown in the following dia-
gram, 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 “Offset” to 0.
Here are offset settings and pitch change produced by vibrato:
-99…+99 Offset value.
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).
Fade
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” affects the LFO (when “Key Sync” is On):
00…99 Fade rate.
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.
Frequency Modulation
You can use two alternate modulation sources to adjust the
speed of the LFO1 for the selected oscillator.

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