Offset
With a setting of 0, vibrato will be applied while keeping the original frequency (at Note-on) at the
center of the vibrato. With a setting of +99, vibrato will be applied only in the upward direction,
similar to the way in which vibrato occurs on a guitar.
For the Guitar waveform, the modulation will be only in the positive direction even if the Offset is
set to 0.

2–2b: Start/KeySync/Delay/Fade
Start
This specifies the time at which the LFO will take effect. This setting is closely dependent on the
Fade setting, so refer to the explanation for Fade as well.
If Key On is selected, the LFO will begin taking effect at note-on. Normally you will set this to Key
On.
If Key Off is selected, the LFO will begin taking effect at note-off.
If Both is selected, the LFO will begin taking effect at note-on, and will stop taking effect at note-
off.
KeySync (Keyboard Sync)
If this is checked it will be On; the LFO will start each time you play a note, and an independent
LFO for each key will be used.
If this is un-checked it will be Off; the LFO effect begun by the first-played note will continue to
apply to subsequently played notes. (In this case, Delay and Fade will apply only to the first-
started LFO.)
Delay
This determines the time from the Note-on (or Note-off) until the LFO begins to take effect. If Key-
Sync is Off, the Delay setting will affect only the first-started LFO.
Fade
With positive (+) settings, this will set the LFO Fade In Time; i.e., the time from when the LFO
begins to take effect until it reaches maximum amplitude.
With negative (–) settings, this will set the LFO Fade Out Time; i.e., the time over which the LFO
amplitude decreases from maximum down to 0.
If KeySync is Off, this will affect only the first-started LFO.
