LFO: Low Frequency Oscillator
L.F.O. stands for Low Frequency
Oscillator. Such oscillators are used to modulate a property in a synthesizer
or effect. It can be used to simulate natural instrument effects, such as
vibrato (by applying LFO to pitch) and tremolo (LFO applied to volume), or can
be used to change gradually a setting to create special effects, such as
applying a LFO to the cutoff value, thus creating phaser-like effect
Ø Rate:
This knob controls the frequency. Turn clockwise for a faster
modulation rate.
Ø Depth:
This knob controls the amplitude. With a lower setting, the
resulting modulation is subtle, while a higher depth will result
in a much more extreme effect.
The following combo
boxes settings adds motion or variability to sounds:
Ø WaveForm: Switches between
‘Triangle’, ‘Sine’, ‘Saw’, ‘Square’ and ‘Exponential’ waveforms.
Ø Source: Switches between ‘Modulation
Wheel’, ‘Aftertouch’ and ‘Velocity’.
Ø Destination: Switches between
‘Pitch’, ‘Expression’ and ‘Pan’ modulation.
