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
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
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
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
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
The A-110-2 Basic VCO is built on the same technical basis as the “standard” VCO A-110-1 that has been available for a long time. Like the A-110-1, it uses circuitry to keep the temperature-sensitive parts of the oscillator at around 50°C. With 8 TE, it is a bit narrower than the 10 TE wide A-110-1, … Read more
Compared to the A-110-4 Quadrature Thru Zero VCO, the A-110-6 has one more thing on top: We are not dealing with a sine core, but with a trapezoid core. This is a unique design that first creates a trapezoidal waveform, as well as a 90 degree phase-shifted trapezoid (the equivalents of the A-110-4‘s sine and … Read more
The A-188-1A module (512 steps) is a discontinued model and will unfortunately no longer be produced in the future. Status: January 2023 BBDs – “Bucket Brigade Devices” are based on (analogue) storage components for voltages that are clocked through quickly by an internal oscillator. The voltage present at the input of the module is picked … Read more
First of all: Wow, what a pompous name! “Quadrature Thru Zero VCO”! That sounds at least like Warp 11, quantum flux compensators and things like that, doesn’t it? The name is actually only topped by the A-110-6 “Trapezoid Thru Zero Quadrature VCO” – we’ll talk about that in a later blog post in this hyperspace … Read more
The A-143-9 Voltage Controlled Quadrature LFO / VCO is a voltage controlled sine wave generator that produces a very clean sine wave signal. With approx. 3 kHz, the LFO reaches into the audio range, with an additional control voltage it can even be used as a VCO up to approx. 20 kHz. Compared to “real” … Read more
