A-111-5 Mini Synthesizer Voice

The A-111-5 is not an oscillator in the traditional sense, but a complete mini synthesizer with VCO, VCF, VCA, ADSR and two LFOs. A “Dark Energy” (first generation) for the modular system! A lot of things here are patchable, but upon closer inspection you’ll see that some signal paths are exclusively internal. For example, there … Read more

A-111-1 High End VCO

The module is no longer in production. The A-111-1 was the high-end model among Doepfer’s oscillators and is only available on the used market. The successor model with some detailed improvements is the A-111-2. Compared to the A-110-1 or A-110-2, the A-111-1 offers expanded synchronization options, an additional input for linear frequency modulation, and a … Read more

A-111-3 Micro Precision VCO / VCLFO

An almost ideal VCO for small, portable module systems: The A-111-3 measures just 4 TE! At its core, it is the same VCO as the A-111-2 High End VCO II, which, however, is much more luxuriously equipped. So, again, we’re dealing with a highly tuning stable oscillator that offers pretty perfect tracking of 1V/octave over … Read more

A-111-6 Miniature Synthesizer Voice

I often used my A-111-5 as a “stopgap” when I quickly needed another simple synthesizer voice and maybe was just too lazy to patch extra VCO, VCF, VCA, ADSR and LFOs for such a secondary voice . I was often plagued by the “guilty conscience of the modularist” when I ignored the far-reaching possibilities of … Read more

A-118-2 Noise / Random / T&H / S&H

The “Slim Line” module is a version of the classic analogue noise generator A-118-1 reduced to half the width (only 4HP). As with the other “Slim Line” modules, slightly smaller buttons and sockets with narrow, round nuts are also used here. The controls are at the top and the sockets are at the bottom, which … Read more

A-112 VC Sampler / Wavetable Osc.

The A-112 is a small digital module that can record, store and play back transposed audio material – a sampler in small format. In addition, the module can also be used for simple wavetable synthesis and as an effects device. The module has two small memory banks (each 64 kbytes in size) to store audio … Read more

A-117 Digital Noise / Random Clock / 808 Sound Source

The A-117 Digital Noise / Random Clock / 808 Sound Source module is a discontinued model and will no longer be produced in the future. Status: February 2024 The Digital Noise Generator A-117 creates random, short impulses. The frequency of these pulses can basically be controlled, namely via the “Rate” controller or alternatively via an … Read more

A-118-1 Noise + Random Voltage

Like the A-117 Digital Noise, the A-118-1 is also a random noise generator. However, it does not work with feedback shift registers, but with the “natural” noise of transistors and thus generates a very typical “synthesizer” noise. Dieter Döpfer once explained to me that due to the component tolerances of these transistors, each A-118-1 sounds … Read more
