Custom Voice Creating G E4: LFO An acronym for Low Frequency Oscillator, a block that produces a low frequency signal. The LFO can be used to modulate pitch, filter cutoff frequency, or amplitude to create a wide range of modulation effects. 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 values 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. • TYPE (LFO wave type) Saw Triangle • DELAY TIME Short Delay Key on • DELAY RATE Rate Key on Delay Long Delay Key on Time 98 Reference 96
