LFO PlsWid When the LFO Shape is set to Pulse, the PlsWid parameter sets the pulse width as a
percentage of the waveform period. The pulse is a square wave when the width is set to
50%. This parameter is active only when the Pulse waveform is selected.
LFO Smooth Smooths the Saw+, Saw-, and Pulse waveforms. For the sawtooth waves, smoothing
makes the waveform more like a triangle wave. For the Pulse wave, smoothing makes the
waveform more like a sine wave.
FilterType The type of resonant filter to be used. May be one of "Lowpass", "Highpass", "Bandpass",
or "Notch".
Min Freq The minimum frequency of the resonant filter. This is the resonant frequency at one of the
extremes of the LFO sweep. The resonant filter frequency will sweep between the Min
Freq and Max Freq.
Max Freq The maximum frequency of the resonant filter. This is resonant frequency at the other
extreme of the LFO sweep. The resonant filter frequency will sweep between the Min Freq
and Max Freq.
Resonance The resonance level of the resonant filter. Resonance sets the level of the resonant peak (or
the amount of cut in the case of the notch filter).
L Phase The phase angle of the left channel LFO relative to the system tempo clock and the right
channel phase.
R Phase The phase angle of the right channel LFO relative to the system tempo clock and the left
channel phase.
