Low Frequency Oscillators
LFOs are special-purpose oscillators that produce a frequency that is
typically below the range of human hearing (although these can actu-
ally extend into the audio range if set to their maximum frequency). The
LFOs are used for periodic modulation such as vibrato (periodic pitch
modulation) and tremolo (periodic amplitude modulation). They can also
be used as modulation sources for any of the many modulatable param-
eters in the Take 5.
The LFOs produce a variety of waveshapes, including triangle, sawtooth,
reverse sawtooth, square, and

h
(sample & hold/random). Though
most often used for low-frequency modulation, the Take 5 LFOs can actu-
ally function at speeds that extend into the audible range for extreme effects.

The Low Frequency Oscillators
The triangle wave is bipolar. That is, its waveshape is positive for half of its
cycle and negative for the other half. This makes it possible to generate a
vibrato that goes alternately sharp and flat in equal amounts on either side of
a center frequency.
The square, sawtooth, reverse sawtooth, and sample & hold (random)
waves generate only positive values. In the case of the square wave, this
makes it possible to generate trills.
