● E4: LFO
An acronym for Low Frequency Oscillator, a block that produces a low frequency sig-
nal. The LFO can be used to modulate pitch, filter cutoff frequency, or amplitude to
create a wide range of modulation effects.
• TYPE (LFO wave type)
• DELAY TIME
• DELAY RATE
Vibrato effect based on LFO modulation, with
a variable delay between the time a key is
played and the beginning of the vibrato effect.
See the diagram below.
Selects the LFO wave. Various kinds of modulated sounds
can be created depending on the selected wave.
See the diagram below.
Sets the speed of LFO variation.
Abbreviation for "Amplitude Modulation." This determines
how greatly the LFO will affect the output level. Larger val-
ues widen the range of the volume change.
Abbreviation for "Filter Modulation." This determines how greatly
the LFO will affect the filter cutoff frequency. Larger values widen
the range of change in the cutoff frequency.
Abbreviation for "Pitch Modulation." This determines how greatly the LFO will affect
the pitch. Larger values widen the range of the change in pitch.
