Low Frequency Oscillators
Triangle and Sample & Hold waves are bipolar. That is, their waveshape is
positive 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 vibrato that goes alter-
nately sharp and at 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 LFOs can be free-running or synced to the Arpeggiator, Sequencer, or
MIDI clock for tempo-synced effects such as lter sweeps, tremolo, and so on.
LFO Parameters (Front Panel)
Frequency: 0...150—Sets the frequency of the selected LFO from a
slow .022Hz to a fast 500Hz. This is affected by the clk sync (clock
sync) parameter as explained below.
Amount: 0...127—Sets the amount of LFO modulation routed to the
selected destination. Setting an amount here applies the selected modula-
tion continuously. You can also use the modulation matrix to route an
LFO to additional destinations and use a different modulation amount if
you want.
Shape: Triangle, Sawtooth, Reverse Sawtooth, Square, S&H—This
button sets the waveshape of the selected LFO.
Destination: Various—Routes the selected LFO to one of the many
modulation destinations within the synthesizer. These appear in the
display. You can also use the modulation matrix to route an LFO to addi-
tional destinations.
