1. Introduction
Module A-145 (LFO) is a low frequency oscillator,
which produces cyclical control voltages in a very wide
range of frequencies.
Five waveforms are available: sawtooth, inverted
sawtooth, triangle, sine and square wave.
The LFO can be used as a modulation source for
any number of modules - for instance modulating the
pulse width or frequency of a VCO, modulation of the
cut-off frequency of a VCF, or amplitude modulation
with a VCA.
A three-way switch lets you select three frequency
ranges, spanning from one cycle every several minu-
tes at the lowest, to audio frequency at the highest.
The LFO signal can also be synchronised, via the
reset input.
