7. Low-Frequency Oscillators (LFOs)
Lurking within Sequencer 1 are three low-frequency oscillators. Like other LFOs, these
oscillators generate periodic voltage signals which can be used to control other modules.
Sequencer 1’s LFOs have a wide variety of wave shapes and are synchronized with the pattern,
regardless of whether you’re using internal or external clocking. At the risk of getting carried
away with ourselves, we’ll mention that you’d pay a substantial fraction of Sequencer 1’s price if
you purchased LFOs this powerful as separate modules.
7.1. Selecting LFOs
Press and hold ALT then press to access the LFO edit pages. Pressing Mod again while
holding ALT advances the LCD from one LFO’s parameters to the next. The LCD indicates
which LFO is currently selected. Each LFO has two pages of parameters.
7.2. LFO Parameters
Shape
The Shape parameter lets you choose one of many different
shapes for the LFO. The shape describes how the LFO's output
changes over time. Usually we speak of the LFO's shape in
terms of what its output does in one cycle; most shapes operate
in a predictable manner, generating an output signal which repeats over and over, once per
cycle. (The randomly generated shapes are the exception.)
The available shapes are shown in the following illustration. Each drawing represents one cycle
of the LFO. The actual output voltages from the LFO depend upon the settings of its Amplitude
and Range parameters, which we’ll describe shortly. In the drawings we’ve labeled the scale
with arbitrary values of MIN and MAX representing the LFO’s minimum and maximum output
voltages.
