The LFO section
Circuit Mono Station has a Low Frequency Oscillator (LFO) whose output may be routed to
various parts of the synth using the Modulation Matrix (see page 82). With fairly slow settings
of Rate, it can typically be used to modulate oscillator frequency to give a vibrato effect or
amplitude for a tremolo effect. It can also be used to great effect to modulate lter frequency

LFO Waveforms
The Wave button
21
select one of four wave shapes - Triangle, (falling) Sawtooth, Square or
Sample and Hold. The LEDs next to the switch conrm the waveform currently selected.
LFO Rate
The speed (or frequency) of the LFO is set by the Rate control
20
. The frequency range is from
zero to about 200 Hz.
LFO Sync
The LFO frequency may be synchronised to the master tempo clock to produce LFO effects
that are musically related to the Pattern timing. Selecting Sync
22
reassigns the function of the
Rate control, and allows the frequency of the LFO to be locked to subdivision of the internal
or external MIDI clock, based on a Sync Rate value selected by the Rate control. See Sync
Values table on page page 48 for a list of available Sync Rates.
