WAVE (WAVE SWITCH)
This switch allows you to select the Waveform of the LFO.
SQUARE: WhentheSquarewaveisselected,theLFOwillalternatebetween
two distinct values representing the upper and lower limits of the wave.

TRIANGLE: The Triangle wave creates a continuously changing value that
sweeps between the upper and lower limits of the wave. Vibrato is a good
example of Triangle wave modulation.
The Low Frequency Oscillator creates a consistent modulation source that can
be used to add a repeating, cyclical change to any of the modulation sources.
It can be used to modulate the Filter Cutoff Frequency, the Pitch of the Oscil-
lator, or the Width of a Pulse wave. Using the Patchable Header, you can also
use the LFO to modulate other parameters, such as the VCA output level. The
WerkstattLFOhasanupperfrequencyofaround600Hz—wellwithinthe
audio range. This ability allows the LFO to create rich and unusual sounds when
modulating the Oscillator pitch or other destinations.
