32 Low Frequency Oscillator
Sequential
The Low-Frequency Oscillator
Triangle and Random waves are bipolar. That is, their waveshape is posi-
tive for half of their cycle and negative for the other half. In the case of the
triangle wave, this makes it possible to generate a natural-sounding vibrato
that goes alternately sharp and flat in equal amounts on either side of a center
frequency. Random, also known as “sample and hold,” generates a series
of random values, each held for the duration of one cycle
The square wave, sawtooth, and reverse sawtooth generate only positive
values. In the case of the square wave this makes it possible to generate natural-
sounding trills.

LFO waveshapes
The Trigon-6 has a sixth “hidden” LFO waveshape that you can use as a
modulation source — noise. To access this, choose
random
then turn
frequency
all the
way clockwise. This generates a white noise waveform.
The LFO can be free-running or synced to the arpeggiator, sequencer, or
MIDI clock for tempo-synced effects such as filter sweeps, tremolo, and so on.
Frequency:
Sets the frequency of the LFO waveshape routed to the
destination. See also “LFO Sync” below.
