Doepfer A-145 Low Frequency Oscillator LFO

Doepfer A-145 Low Frequency Oscillator LFO

Module A-145 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 minutes at the lowest, to moderate audio frequency at the highest (about 4-5 kHz).

The LFO signal can also be synchronised, via the reset input.
