LinPlug Spectral - Manual (Page 41)

LFOs
The Spectral’s LFO (“Low Frequency Oscillator”) modules are located on
the right of the instrument’s user interface, below the filter, sharing the area
with the Filter envelopes.
An LFO is an oscillator that generates (rather) low frequency signals which
can be used to modulate one of Spectral parameters, for example the Filter
frequency or an Oscillators volume. Spectral contains 5 separate LFOs
which are identical but fully independent.
The Spectral's LFOs are much more powerful than it seems at first, so in
case you are not consider yourself a power user you might maybe skip the
in depth descriptions and just go with the “LFOs made easy” summary:
Each of the LFOs can be used to modulate a range of destinations which
are to be set using the Spectral’s Mod Matrix (see the next chapter for more
information about the Mod Matrix). There exists no predefined modulation
of any kind, when an LFO not appears in the Mod Matrix, it does not affect
the sound, you can also see this on the slightly dimmed LFO button on the
very right.
On the top right you find the Tool Menu as described in the Tool Menu info
box on page 15.
LFOs made easy-to-use
In case you don't need to fancy features and possibilities you may
work with much less of the LFO's options:
Select the Poly (oo) or Mono (M) mode depending on whether or
not you want to have each voice its own LFO.
Select your desired waveform below (most of the time Triangle
serves well) and keep the menu below at its “Normal” setting.
You can adjust the tempos with the Tempo dial and switch between
Hz and a synced tempo in the display above the Tempo dial.
Forget about Sym and Smooth, Phase, Delay and Attack (Ctrl-Click
on PC and Command-Click on Mac resets them to a useful default)
until you are ready to explore the LFO's deeper.
