LFO
Waveform
Waveform
Triangle, Sine, Saw Up, Saw Down, Square, Sample & Hold. This selects the
waveform of the LFO.
Shape
+/-100. This adjusts the shape of the LFO waveform, from logarithmic to linear to
exponential. Positive values shape the waveform so that it spends more time in the
"up" part of the cycle, and negative values make it spend more time in the "down"
part of the cycle, as shown below.
LFO Shape
Smoothing
0-100. This allows you to filter the LFO waveform, so that it becomes more
rounded, less angular. With moderately high amounts of smoothing, the triangle
and square waveforms will start to approximate sine waves, and the discontinuous
peaks of the saw waveforms will become smooth transitions. With very high
amounts of smoothing, the waveform may loose much of its shape, and fall quite
short of its maximum and minimum values.
