1. Introduction
Module A-147 (VCLFO) is a voltage controlled low
frequency oscillator, which can produce cyclical con-
trol voltages over a 0.01Hz to 50Hz frequency range.
The VCLFO can be patched as a modulation source
for a wide range of modules (for instance, modulation
of VCO pulse-width or frequency, VCF cut-off fre-
quency, VCA amplitude modulation) and as a provider
of repetitive or clock voltages (for instance to drive the
A-161 clock sequencer).
Four waveforms are available: triangle, sine, square,
and falling sawtooth waves.
The VCLFO's frequency can be controlled by hand,
but also by voltage control.
You can sync the VCLFO to another waveform by
connecting the other waveform (eg another LFO) to
the VCLFO’s reset input.
