LFO
LFO: Low Frequency Oscillator
The Low Frequency Oscillator creates a repeat-
ing cyclical signal. You can choose one of three
LFO waveforms.
Depending on its target, the LFO can provide
vibrato (PITCH); Tonal changes to the Oscillators (SHAPE); or Wah-Wah (CUTOFF)
effects.
WAVE switch
The LFO can be set to a square wave ( ), a triangle wave ( ), or a sawtooth wave
( ).
MODE switch
Specifies the range of change and action for the LFO frequency.
BPM: The LFO frequency synchronizes with the BPM of the arpeggiator.
SLOW: The range of change for the LFO frequency will be from 0.05 Hz–28 Hz.
FAST: The range of change for the LFO frequency will be from 0.5 Hz–2.8 kHz.
RATE knob
The rate knob adjusts the speed of the LFO.
Turning the knob to the right will increase the LFO speed.
INT knob
The INT knob adjusts the intensity of the LFO.
Turning the knob to the right will increase the LFO intensity.
When turning the INT knob while holding down the SHIFT button, the
TIP
LFO waveform will be inverted. The setting range is 0– -511.
TARGET switch
Selects where the LFO modulation will be applied.
CUTOFF: Modulation is applied according to the VCF CUTOFF knob setting.
SHAPE: Modulation is applied according to the SHAPE knob setting for the oscilla-
tor, which is set in "LFO Target OSC" (p.48) of PROGRAM EDIT mode.
PITCH: Modulation is applied according to the PITCH knob setting for the oscilla-
tor, which is set in "LFO Target OSC" (p.48) of PROGRAM EDIT mode.
