Doepfer A-111-6 Miniature Synthesizer Slim Line

The Doepfer A-111-6 is a complete analog synthesizer voice condensed into just 10HP, combining a triangle-core VCO, -24dB low-pass filter, VCA, and voltage-controllable envelope. Designed for efficient patching, the internal normalisations allow it to be played with just a CV and gate input. 

In our opinion this is the best analogue voice module in eurorack. Can't be beaten on price or sound. 

The oscillator provides saw, triangle, and pulse waveforms, with manual pulse width control and switchable FM or PWM modulation. A sub-oscillator or external signal can be blended in via the balance control. The filter offers two FM inputs and self-oscillation, enabling use as a sine oscillator when the VCO is bypassed.

The envelope supports AD, AR, and full ADSR modes, and its timing can be voltage controlled via a dedicated CV input. The VCA offers a mix of exponential and linear response and can be switched between gate, envelope, or manual control. This compact voice is ideal for minimal systems or performance-focused racks.
