LFO
LFO is an acronym for Low Frequency Oscillator. The frequency of the modulation source changes so slowly
that if functions as an influence over volume, filter frequency, and other non audio rate aspects of voltage
control. The SE-02 offers LFO control over the filter, the pitch and the volume of its output. Here you can
create cyclic change (modulation) in the sound by applying vibrato (pitch modulation) or tremolo (volume
modulation).
RATE
Adjusts the LFO frequency. This is how slow or how fast the LFO changes.
Experiment: Choose a sound you like. Now turn the FILTER knob of the LFO section up to 12 o’clock. Adjust the
RATE of the LFO and listen to the changes. Adjust the main FILTER frequency and see how the LFO effects the
relationship between the filter and low frequency oscillator.
WAVE
These are the wave shapes which the LFO is able to take.
SAMPLE & HOLD
SINE
TRIANGLE
SAWTOOTH
REVERSE SAWTOOTH
SQUARE 1
SQUARE 2 (pulse Wide)
SQUARE 3 (pulse Narrow)
RANDOM
OSC
Adjusts the depth to which the LFO affects the oscillator. This will apply an LFO to the pitch of the Oscillator
section. Full counter clockwise will turn this effect completely off. As you rotate the knob clockwise the effect of the
LFO on the oscillator section increases.
FILTER
Adjusts the depth to which the LFO affects the filter. As demonstrated in the RATE experiment, this is where you
set the amount which the LFO will apply to the filter frequency. Counter clockwise will turn the LFO filter relationship off
completely. Rotating the LFO FILTER knob clockwise will increase the effect.
