A-100 analog modular Website
The module is small and interesting. A stripped down to two parameters but still flexible envelope generator with voltage control, hardwired to a linear VCA, plus a ducking function. The whole thing is also designed twice on only 8 HP. This is made possible by the new “Slim Line” format with slightly smaller buttons and … Read more
The A-177-2 Foot Controller module is a connection module for a foot controller and a double foot switch. This is not simply a large-to-small multiple, but the module actively generates control voltages or gate signals that are controlled by electrically passive foot switches / foot controllers. A large-to-small multiple, on the other hand, would be … Read more
The module is no longer in production. The A-144 Morphing Controller generates control voltages that are used, for example, to regulate four linear VCAs of a voltage-controlled mixer in such a way that the four input signals of the mixer are morphed one after the other. The A-135-1 or A-135-2 Voltage Controlled Mixer and the … Read more
The A-198 Trautonium / Ribbon Controller originates from Doepfer’s Trautonium project, which attempted to recreate the components of a Trautonium using modern A-100 modules. Compared to the console of the original, the ribbon controller is playable with significantly less nuance: the original was a fine metal string with several centimeters of pressure travel. Of course, … Read more
The A-170 Dual Slew Limiter smooths control voltages – abrupt changes are “smeared” in the process. Switched before the frequency control of an oscillator, this function causes the well-known “portamento”, which transforms a jump on the keyboard into a slurred note. The two sub-modules differ, the upper slew limiter only allows a simple adjustment of … Read more
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
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
The A-149-1 Quantized / Stored Random Voltages is a lavishly equipped random generator that is based on the Buchla modules 265 and 266. There are two different sub-modules: Quantized Random Voltages provides random voltages whose level is within a “grid”, a quantization. These are then distances of 1 V at output “n+1” and distances of … Read more
Compared to the rather unpretentious predecessor A-147, the new VCDLFO (Voltage Controlled Delayed LFO) is a monster. No fewer than 12 connection sockets on a module that is only 8 HP wide are already an announcement in terms of complexity in a confined space. In fact, Doepfer added a delay function to the voltage-controlled LFO … Read more
The module is no longer in production. The A-167 Analog Comparator can compare voltages with each other and generate a gate signal. There are many possibilities: comparison of two external voltages, comparison of a voltage (normal or inverted) with a positive or negative threshold value, comparison of the difference between two external voltages with a … Read more
