Editing a program LFO
11
LFO
These are the parameters for the LFOs (Low Frequency
Oscillators). An LFO can apply cyclic change to the sound.
LFO1 is internally connected as the modulation source for
oscillator 1 waveform.
LFO2 is internally connected as the modulation source for
the oscillator pitch modulation controlled by the joy-stick.
You can also use a virtual patch to assign an LFO as a
modulation source for other parameters. For more
information, please see “Virtual Patch” on page 11.
Waveform, speed (frequency), and tempo synchronization
can be edited in the PROG P5-4: LFO1 or P5-5: LFO2 pages.
LFO waveform
1. Use “Waveform” to select the basic waveform of the
LFO.
The change produced by the LFO depends on the
waveform. Select various waveforms and notice the
difference in how they affect the sound.
2. Use “Phase” to specify the starting position of the
waveform.
Notice that this setting moves the waveform to left or right.
You can create interesting effects by offsetting the phase of
one LFO relative to the other LFO.
This parameter is available when Key Sync is 1st Note or
Each Note.
3. Use “Shape” to modify the basic waveform of the LFO.
The change produced by this parameter will depend on the
Waveform you’ve selected.
4. Use “Frequency [Hz]” to specify the frequency of the
formant motion.
This parameter is valid if MIDI/Tempo Sync. is Off
(unchecked).
MIDI/Tempo Sync
1. Use “MIDI/Tempo Sync.” to specify how the LFO will
synchronize.
If this is On (checked), the LFO will synchronize to the
system tempo specified by the TEMPO knob or TAP
TEMPO switch, or to the MIDI Clock from an external
device.
2. Use “Base Note” to specify the LFO cycle.
This specifies the ratio of the LFO cycle relative to the
system tempo or external MIDI clock. This parameter is
valid if MIDI/Tempo Sync. is On (checked).
Virtual Patch
These are the parameters for the Virtual Patch function.
Virtual Patch is a function that lets you assign modulation
sources such as EG or LFO to a variety of parameters. For
each timbre you can create up to eight of these
combinations.
Make these settings in the PROG P1-2: Virtual Patch page.
Virtual Patch settings
1. Use “Src (Source)” to select a modulation source.
You can select EG, LFO, or various controllers as a
modulation source.
For more information, please see “Src (Source)” on page 28.
2. Use “Dst (Destination)” to select the parameter that
will be modulated.
For more information, please see “Dst (Destination)” on
page 28.
3. Use “Int (Intensity)” to specify the depth of
modulation.
Controlling volume
If you set Src (Source) to LFO2, Dst (Destination) to Amp
Level, and adjust Int (Intensity) as desired, LFO2 will
produce a tremolo effect.
Controlling pan
If you set Src (Source) to LFO2, Dst (Destination) to Pan,
and adjust Int (Intensity) as desired, LFO2 will move the
sound between left and right to produce an auto pan effect.
Controlling filter
If you set Src (Source) to LFO2, Dst (Destination) to Filter
A Frequency, and adjust Int (Intensity) as desired, LFO2
will vary the filter cutoff frequency to produce an auto wah
effect.
You can use an LFO to modulate a wide range of parameters
in addition to those listed above.
