LFO MODULE
The Low Frequency Oscillator (LFO) module is a modulation source for
animating your delay time and for varying of the pitch and time. Unlike
traditional delays, our LFO uses exponential modulation for musical and
balanced movement in a musical frequency domain, the way the ear and
brain want to hear it. In the synthesizer world this is the familiar
Volt/Octave tracking used for pitch and amplitude. Our modulation is
symmetrical around the TIME setting, changing above and below it. This
means that as you reduce the LFO amount the pitch and time will stay
centered, where you have it, and not shift offset with the AMOUNT setting
(requiring TIME to be adjusted) as with traditional modulation.
RATE:
The RATE knob adjusts the speed
or rate of modulation from about 0.08Hz
to 40Hz (wider range via control voltages).
Lower settings provide a slow whoosh or a
rhythmic pitch shift. Medium speeds are a
chorus like effect while faster rates
provide a gargle, bubble or vibrato sounds.
AMOUNT:
The AMOUNT knob controls
the range of pitch movement at the speed
of the LFO, or the amount of effect. Use low amounts for subtle shimmer
and larger amounts for octave or greater pitch shifts or spaceship warbles.
LFO SHAPE SWITCH:
Selects a slewed square wave(up), a rounded
triangle wave (down) or off (center). At higher speeds the shape becomes
more and more rounded or slewed. Use triangle wave for traditional
gradual ramped modulation and square waves for rapid pitch jumps above
and below the note played.
Be sure to read the control voltage section for information on this module
with expression pedals or control voltages.
