The A-145 is a low frequency oscillator which produces cyclic 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 (vibrato), modulation of a VCF or amplitude modulation of the VCA (tremolo). A three way switch selects three frequency ranges ranging form one cycle every several minutes at the lowest to audio frequency at the highest. The LFO signal can also be synchronised via the reset input.
