THE LFO PAGE
LFO 2
The controls in this section are used to affect the characteristics of
LFO 2, and determine which parameters it will modulate. Many of the
parameters are identical in function to their counterparts in LFO 1.
> RATE
This determines how fast LFO 2 will oscillate. The higher the value,
the faster it will oscillate.
> CLOCK
This overrides Rate and forces LFO 2 to sync its wave cycle to the
clock control. The fractions are relative to a whole note, or semi-
breve, which in turn are equivalent to a whole bar/measure in 4/4
time. So, by choosing a clock rate of 1/4, LFO 2 will sync to a quarter
note (crotchet) cycle, whereas a setting of 4/1 will cause it to sync to
cycle of 4 bars.
> SHAPE
This determines the waveform of LFO 2 - different waves can result in very different modula-
tion effects. Choose between the following options:
>Sine:
A smooth up/down cyclic wave.
>Triangle:
Similar to sine wave, but with sharper peaks and a linear curve.
>Sawtooth :
This will cause the sound to rise/fall, then jump back suddenly to rise/
fall again.
>Square:
Use this to jump back and forth between two values.
>Sample and Hold (Random):
This isn’t a waveform as such – instead LFO1 will
generate random values, causing the affected parameter(s) to jump around unpre-
dictably.
>Sample and Glide :
Like Sample and Hold, this generates random values
between which the LFO will interpolate smoothly, causing the affected parameter(s)
to slide up and down unpredictably.
