3. a little the philosophy of this control method which might seem odd to those used to chorus flange effects where you set the delay time in ms directly Depth LFO The Depth LFO modulates the Depth value set above It has simple speed and depth controls This is most useful when bias see below is set to 1 0 though you can of course use it whenever you like and it will always do some thing to the sound Shape The Shape knob changes the shape of the LFO waveform There are 5 key shapes and the control blends between them smoothly The shapes are e 0 Sine an ordinary sinusoidal waveform useful for regular vi brato effects e 1 Saw Up The pitch rises from a minimum to a maximum value then suddenly falls back to the minimum e 2 Saw Down The pitch falls from a maximum to a minimum value then suddenly rises back to the maximum e 3 Tri a triangle wave Similar to Sine but sounds slightly different e 4 Square a square wave The pitch simply alternates between two values The Spread knob introduces an offset in the LFO phase for each channel that the plug in is processing In the common case of a stereo plug in this amounts to altering the LFO phase of the right channel Since the pitch of the vibrato at any point in time depends on the LFO phase the spread control effectively introduces a pitch difference between the channels This results in a wider soun
