4.2.10 The LFO Module

The LFO module is used as a modulation source for the Filter module. On the LFO module, one

can adjust the waveform, rate and fade-in behavior.

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 rectangular 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 de-

termined by the Sync Rate 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.
