OSC1 LFO1
This page has all of the controls for the first LFO of Oscilla‐
tor 1. For instance, you can:
tor 1. For instance, you can:
• Control the LFO’s frequency, and assign AMS controllers
to modulate the frequency.
• Use the “Key Sync” parameter to choose whether the
LFO runs separately for each voice, or is synchronized
across all of the voices
across all of the voices
• Use the “Fade” and “Delay” parameters to control how
long the LFO waits to start after note‐on, and whether it
starts abruptly or fades in slowly.

• Set the LFO to sync to MIDI tempo.

Shape AMS Src
[List of AMS Sources]
This selects an AMS source for controlling the LFO’s Shape.
Modulating the shape can dramatically alter the effect of the
LFO–try it out!
For a list of AMS sources, please see “Alternate Modulation
Source (AMS)” on page 121.

Stop
[Off, On]
On: Instead of the LFO functioning normally, it will ignore
the Freq setting. The LFO will maintain the initial value
(determined by the performance of Waveform, Phase,
Shape, and Offset) until the note‐off.
Since the value will change only at note‐on, using a Random
waveform will produce a fixed value that changes randomly
at each note‐on (or at the first note‐on).
Off: The LFO will function normally.

Off: The LFO will function normally.
Key Sync.
[Off, On]
On: 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: When Key Sync is Off, the LFO starts from the phase
thatʹs 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
[–99...+99]
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.

Offset settings and pitch change produced by vibrato
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 wave‐
form 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 impor‐
tant to note that it affects the signal after the Shape function,
as shown below:

Fade
[00...99]
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.

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