5-8: Common Lfo - Korg M3 Parameter Manual

5–8: Common LFO
5–8a
5–8b
5–8c
This is a single, Common LFO, global for all voices in the
Program–like the modulation LFOs in some vintage analog
synths.
Differences from LFO1/2
The Common LFO starts running as soon as you select the
Program, and only resets when you tell it to do so explicitly
via the Reset Source control, below. This is different from
LFO1/2's Key Sync parameter, which resets whenever all
notes are released.
The Common LFO's persistence can be handy if you want to
create a constant rhythm with an LFO, and then play
"underneath" that rhythm without re-triggering it. For
instance, you can use a MIDI controller in your sequencer to
reset the Common LFO every few bars, regardless of what
notes are being played.
The Common LFO has most of the same controls as LFO1/2.
However, it does not include the Delay, Fade, and Key Sync
settings, since these only make sense for per-voice LFOs.
5–8a: Common LFO
Waveform [Triangle...Random6 (Continuous)]
This selects the basic LFO waveform. For a complete list of
the waveforms and more details, please see the entry under
LFO1 "Waveform," on page 66.
Phase
The Reset AMS, described above, lets you reset the
Common LFO. This is the phase from which the LFO will
start when it is reset.
Freq (Frequency)
This controls the speed of the LFO, before any modulation.
Higher values mean faster speeds. For a complete
description, please see the entry under LFO1 "Freq
(Frequency)," on page 66.
Stop
On (checked): Instead of the LFO operating normally, it will
ignore the Freq setting. Instead, the LFO simply generate a
single value when the Program is selected, and then holds
that value until you select another Program, or until you
reset the LFO via AMS.
Note: This is different from LFO1/2, in which the value is
reset with every note-on.
You can use this in conjunction with the Random
waveforms to create static, random modulation, with the
value changing only when you first select the Program.
Off (unchecked): When Stop is Off, the LFO will function
normally.

Shape
Shape adds curvature to the basic waveform. For more
details, please see the entry under LFO1 "Shape," on
page 66.
Note: Shape does not affect the Square and Random3
waveforms, since their values are always either +99 or –99.
AMS (Shape)
This selects a 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 "AMS (Alternate
Modulation Source) List" on page 588.
AMS Int (AMS Intensity)
This controls the depth and direction of the AMS (Shape)
modulation.
Reset AMS
This selects an AMS source to reset the LFO to the Start
Phase. The LFO resets when the AMS value passes the
halfway mark: +50 for most AMS sources, or 64 for MIDI
controllers.
To create an effect similar to the per-voice LFO's Key Sync.
setting, set this to Gate 2+ Damper.
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 a complete description, please see the entry under LFO1
"Offset," on page 67.
5–8b: Frequency Modulation
These parameters are identical to the Frequency Modulation
settings for LFO1, as described under "5–1b: Frequency
Modulation," on page 67.
5–8c: Frequency MIDI/Tempo Sync
These parameters are identical to the Frequency MIDI/
Tempo Sync for LFO1, as described under "5–1c: Frequency
MIDI/Tempo Sync.," on page 68.
