Determines the offset value of the level of each Amplitude Scale Break Point. 1-2-11 LFO (Low-Frequency Oscillator) The Low-Frequency Oscillator (LFO) unit of the tone generator block generates a lowfrequency signal. The signal from the LFO can be used to modulate the pitch, filter, and amplitude. Modulating the pitch produces a vibrato effect, modulating the filter produces a wah effect, and modulating the amplitude produces a tremolo effect. You can set the Common LFO which set the basic LFO parameters common to all Elements of the Voice. Also, you can set the Element LFO which set the LFO parameters for each individual Element. LFO Wave Play Mode Speed Selects the Wave and determines how the LFO waveform modulates the sound. Determines whether the LFO cycles repeatedly (loop) or only once (one shot). Determines the speed of the LFO Wave. The higher the value, the faster the speed. 34
