Key Features
The Doepfer A-111-4 Quad Precision VCO comprises of 4 VCOs, each complete with individual controls, inputs, and outputs for shaping sound. Each VCO comes with triangle and sawtooth waveforms, octave switch, frequency modulation, pulse width modulation, and more, providing you with a chunky sounding monophonic VCO, ideal for creating beefy basslines and leads. With the 4 VCOs you can create polyphonic patches as well. With a wide range of controls, plus 4 individual VCOs, the Doepfer A-111-4 allows for more complex patches. Included with the Quad Precision VCO is a master section, complete with octave switch, tune control, frequency modulation, and waveform sum output, allowing you to control all VCOs together.

The 4 VCOs allow you to create a range of patches including chunky basslines, soaring leads, lush chords, and more. The Doepfer A-111-4 provides a beefy, analogue sound, with its core waveforms as triangle, sawtooth, and rectangle. Each VCO comes packed with individual controls, inputs and outputs, allowing you to fine-tune each VCO to produce a wide range of tones and sounds. Featured with each VCO is a 1V/octave CV input, with a +/-1 octave switch, and tune control for managing the pitch. Each contains a switch for the modulation destination, allowing you to choose between exponential frequency modulation and linear frequency modulation(or pulse width modulation of the rectangle via the jumper). Triangle, sawtooth, and rectangle outputs are available for each VCO, allowing you to patch in and create a vast range of sounds.
Whilst there is a master section for controlling all the VCOs together, the Doepfer A-111-4 provides you with individual controls for each of the VCOs. You can choose to use just one of the VCOs to create a bass, or add 2 or 3 more to bring in more harmonics. With a simple design consisting of 2 potentiometers, modulation switch, and inputs and outputs for each VCO, the Doepfer A-111-4 manages to provide you with a wide sound palette, allowing you to create both simple and complex patches.
