5.4 LFO Overview

Typically an LFO or Low Frequency Oscillator operates below audio ranges
and traditionally is used purely as a modulation source. The singular LFO
also is designed as a modulation source with enhanced features including
the ability to operate at audio levels. The LFO can therefore perform as an
additional sound generator.

Manually sets the LFO speed.

2

Mod amount

Knob

Adjusts the amount of CV applied from the MOD
pin for external modulation control.

3

Pin

Connects an external modulation CV to control
the frequency.

4

LFO Rate
indication

LED

Flashes at the LFO frequency rate.

5

Input for
synchronisation

Resets the start of the LFO. This will synchronise
the LFO to the pulse such as drum trigger or
clock divider.

Higher frequencies will generate a waveform in the audio range that can be used as an
audio oscillator and an additional sound generator. Whether the triangle or square wave
output is used in the audio range the LFO (

TRIANGLE

) shape and (AMT) will affect the

audio as well as the (FREQ) control setting.
