4.13 The LFO Module
The LFO module is used as a modulation source for the Filter mod-
ule. On the LFO module, one can adjust the waveform, rate and fade-in
behavior.
4.13.1 Wave Shape
The waveform of the LFO is selected with the Shape drop-down menu.
The possible values are Sine for sinus, Tri for triangular, Rect for rec-
tangular and Rdm1 and Rdm2 for the two random modes. When the
Shape control is set to Rdm1, the LFO outputs random values at the rate determined by the Sync
control or the Rate knob. In this case, the output value from the LFO remains constant until a new
random value is introduced. The Rdm2 mode reacts almost like the preceding mode except that the
LFO module ramps up or down between successive random values instead of switching instantly
to the new value.
