24.1.7 LFOs
Display and Shell Parameters for the two LFOs.
Analog’s two LFOs can be used as modulation sources for the oscillators, filters and amplifiers.
As with the other sections, each LFO has independent parameters.
The LFO 1 and LFO 2 switches in the shell toggle the respective LFO on and off, while the Rate
knob sets the LFO’s speed. The switch next to this knob toggles the Rate between frequency in
Hertz and tempo-synced beat divisions.
The Wave chooser in the display selects the waveform for the LFO. The choices are sine, tri-
angle, rectangle and two types of noise. The first noise type steps between random values while
the second uses smooth ramps. With Tri or Rect selected, the Width slider allows you to adjust
the pulse width of the waveform. With Tri selected, low Width values shift the waveform towards
an upwards sawtooth, while higher values result in a downward saw. At 50%, the waveform is a
perfect triangle. The behavior is similar with the Rect setting. At 50%, the waveform is a perfect
square wave, while lower and higher values result in negative or positive pulses, respectively.
Note that Width is disabled when the LFO’s waveform is set to sine or the noise modes.
The Delay slider sets how long it will take for the LFO to start after the note begins, while Attack
sets how long it takes the LFO to reach its full amplitude.
With Retrig enabled, the LFO restarts at the same position in its phase each time a note is trig-
gered. The Offset slider adjusts the phase of the LFO’s waveform.
