Doepfer A-143-4 Quad LFO.jpg

The Doepfer A-143-4 is a Quad LFO and VCO module with external CV control.


A143-4 is a powerful modulation source that can also function as a four voice oscillator. Each section includes frequency controls, square and triangle outputs, reset switch and a range control for determining either LFO or VCO frequency ranges.


Channel D is unique in this module as it includes dedicated reset and direction inputs with direction control, whereas the other channels use a combi input.


CV input 1 allows for 1 v/oct key tracking when the channel is used as a VCO, CV input 2 also controls frequency but features a dedicated attenuator.


Common inputs and control section provide control across all four channels at once, especially handy when using this module as a four voice VCO, as all key tracking takes place at the same time.

Four channel LFO or VCO


1 v/oct tracking


LFO and VCO frequency selection
