LOW FREQ OSCILLATOR (LFO)
LFO (Low Frequency Oscillator) is an oscillator that
creates an oscillation below the threshold of audibility.
This can be used to continuously control different
parameters (e.g. to control the WAVES, the FILTER or the
pitch of the oscillator).
The PPG Wave 3.V’s LFO offers four different oscillator
waveforms as modulation signal. Modulation intensity can
be controlled with the modulation wheel (MODWHEEL).
If it is fully turned down, no modulation takes place. Same
as on the original PPG Wave synth, the Modulation wheel
setting is saved with each Program. Make sure that the
TOUCH
parameter in the MODULATION panel is set to
OFF, otherwise the LFO will only modulate the signal if
Aftertouch data is generated at the same time.
The LFO can also be synchronized to the Song tempo of
your host application by clicking the red LED next to the
RATE knob.
w
The original PPG LFOs were calculated with a very
low update rate, as back then the available processor
power had to be carefully distributed to the various
tasks. In the PPG Wave 3.V you can get the same low
update rate if you activate TRUE PPG.
DELAY
This parameter enables a time delayed LFO modulation.
w
If TRUE PPG is deactivated, DELAY doesn’t have an
impact when set to zero. If TRUE PPG is active, the
LFO is faded in with any new key that you press,
irrespective of the DELAY parameter setting
.
WAVESHAPE
The LFO can create the following four waveforms:
Triangle, falling saw tooth, rising saw tooth and Square.
You can use this control to select one of these waveforms.
