The Doepfer A-111-3 uPVCO Micro Precision VCO / VCLFO is a compact yet versatile module, perfect for your Eurorack setup. Switchable between VCO and LFO modes, it offers a broad range of sonic possibilities, from deep bass lines to animated modulations. This module stands out with its four simultaneous waveform outputs: sine, triangle, saw, and rectangle. The rectangle wave's pulse width can be modulated via CV or manual control, giving you flexibility in sound design.

The core sawtooth oscillator is the heart of the A-111-3, generating waveforms with a distinctive character that synth enthusiasts love. With the ability to adjust the tuning range via jumper settings, you can tailor the frequency response to suit your needs, whether you're aiming for precise pitches or experimental soundscapes. Its compact 4HP width makes it an efficient addition to any rack, while the voltage-controlled frequency modulation adds another layer of creative potential.

Ideal for both beginners and seasoned modular users, the Doepfer A-111-3 offers a blend of precision and character, making it a staple in any modular synthesizer system.
