Korg Electric Keyboard ユーザーズマニュアル

  Key Sync. will be On. The LFO will start 

each time you play a note, and an independent LFO will 
operate for each note.
Off (unchecked): 

Key Sync. will be Off, and 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.)

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)

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.

You can use two alternate modulation sources to adjust the 
speed of the OSC1 LFO1.

Indicates the source that will adjust the frequency of the 
oscillator 1 LFO1 (☞p.212 “AMS List”). OSC1 LFO1 can be 
modulated by OSC1 LFO2.

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 No., positive 
(+) values

 of this parameter will cause the oscillator 1 LFO 

to speed up as you play higher notes. Negative (–) values 
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 #01, raising the value 
of this parameter will cause the oscillator 1 LFO1 speed to 
increase as the joystick is moved away from yourself. With a 
setting of +99, moving the joystick all the way away from 
yourself will increase the LFO speed by approximately 64 
times.

Indicates settings for a second alternate modulation source 
that will adjust the frequency of the oscillator 1 LFO1. 

☞ “AMS1 (Freq. AMS1),” “Int. (AMS1 Intensity)”

  The LFO frequency will synchronize to the 

tempo (MIDI Clock). In this case, the values you specified 
for “Frequency” (5.3–1a) and “Freq.Mod” (5.3–1b) will be 
ignored.

When “Sync. (MIDI/Tempo Sync.).” is checked, these When 
“Sync. (MIDI/Tempo Sync.)” is checked, these parameters 
specify a note length “Base Note (Sync. Base Note)” relative 
to “

 (Tempo)” and the multiple “Times (Sync. Times)” that 

will be applied to it. These parameters will determine the 
frequency of the OSC1 LFO1. For example if “Base Note 
(Sync. Base Note)” is 

 (quarter note) and “Times (Sync. 

Times)” is 04, the LFO will perform one cycle every four 
beats.
Even if you change the “

 (Tempo)” setting of the arpeggia-

tor or sequencer, the LFO will always perform one cycle 
every four beats.

☞ “Write Program” (1.1–1c)

This exchanges the settings of LFO 1 and 2. If LFO2 is 
selected in AMS1 (Freq. AMS1) or AMS2 (Freq. AMS2) of 
LFO1 Freq.Mod (5.3–1b), then these settings will be invalid 
for LFO2 after LFO1 and 2 have been exchanged. If you 
select this from the OSC1 LFO1 or OSC1 LFO2 page, LFO1 
and LFO2 of OSC1 will be exchanged.

To execute, press the [F8] (“OK”) key. To cancel without 
executing, press the [F7] (“Cancel”) key.

Here you can make settings for the OSC1 LFO2, which is the 
second LFO that can be applied to oscillator 1. (☞“5.3–1: 
OS1LFO1 (OSC1 LFO1)”) However, it is not possible to use 
the LFO to apply modulation in “AMS1 (Freq. AMS1)” or 
“AMS2 (Freq. AMS2)” of Freq. Mod.

This can be used when “Mode (Oscillator Mode)” (2.1–1a) is 
set to Double. Here you can make settings for the OSC2 
LFO1, which is the first LFO that can be applied to oscillator 
2 (☞“5.3–1: OS1LFO1 (OSC1 LFO1)”).
