determined by the combination of the Waveform, Start
Phase, Shape, and Offset), and then holds that value until
the end of the note.
You can use this in conjunction with the Random waveforms
to create static, random modulation, with the value changing
only at note-on.
Off (unchecked): When Stop is Off, the LFO will function
normally.
Key Sync
On (checked): When Key Sync is On, the LFO starts each
time you press a key, and an independent LFO runs for each
note. This is the normal setting.
Off (unchecked): When Key Sync is Off, the LFO starts
from the phase determined by the first note in the phrase, so
that the LFOs for all notes being held are synchronized
together. The Fade and Delay settings will only apply to the
first note's LFO.
Note that even if Key Sync is Off, each note's LFO speed
may still be different if you modulate the Frequency by note
number, velocity, key scaling, or other note-specific AMS
sources.
Offset
By default, almost all of the LFO waveforms are centered
around 0, and then swing all the way from -99 to +99. This
parameter lets you shift the LFO up and down, so that–for
instance–it's centered on 50, and then swings from -49 to
+149.
For example, let's say that you're using an LFO for vibrato.
If the Offset is 0, the vibrato will be centered on the note's
original pitch, bending it both up and down.
If the Offset is +99, on the other hand, the vibrato will only
raise the pitch above the original note.

O ffset = –9 9 O ffset = 0
Pitch
The one exception to this is the Guitar waveform, which is
designed to emulate bending a string on a guitar–so that the
pitch only goes up, and not down. Because of this, the
waveform is centered on 50, and not on 0. Of course, you
can always use a negative Offset to shift it back down below
0 again!
Since Offset affects the output values of the LFO, it's
important to note that it affects the signal after the Shape
function, as shown below:

Fade
The LFO can fade in gradually, instead of simply starting
immediately at full strength. This parameter specifies the
time from when the LFO begins to play until it reaches its
maximum amplitude.
If the Delay parameter is being used, then the fade will begin
after the delay is complete.
When Key Sync is Off, the fade will apply only to the first
note in the phrase.

Delay
This sets the time from note-on until the LFO starts.
When Key Sync is Off, the delay applies only to the first

note of the phrase.
8–2b: Frequency Modulation
You can use two alternate modulation sources (AMS) to
adjust the speed of the LFO.
AMS1
This selects the first modulation source for the LFO
frequency. For a list of AMS sources, see "Alternate
Modulation Source (AMS) List" on page 1109.
Note that you can use LFO2 to modulate LFO1's frequency.
Intensity
O ffset = + 9 9
This sets the initial amount of AMS1. The Intensity Mod
AMS then adds to this initial amount.
When AMS1 is at its maximum value (for instance, when the
joystick is pushed all the way up), the AMS affects the
frequency as shown below:
