A-100 analog modular Website
Andreas Krebs 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-150-1 Dual Voltage Controlled Switch has two identical submodules. Each of the submodules is a bidirectional 2:1 switch, i.e. inputs and outputs can be swapped in this module. This gives us two possible uses: The choice of which input is connected to the output or which output is connected to the input is made … Read more
The A-154 Sequencer Controller can control one or two A-155 Sequencers and greatly expands their functionality. The connection between A-154 and A-155 is made directly on the circuit boards via ribbon cables. The clock signals of the A-154 and all control functions are transmitted here. A clock that can be synchronized and support for “16 … Read more
The A-160-2 actually does exactly what I always wanted from a clock divider. It splits an incoming clock signal in a “musical” way. What does that mean? A simple clock divider like the old A-160-1 counts the input triggers, so to speak, and always divides them into two equal halves, depending on the division factor. … Read more
The A-160-1 Clock Divider can generate slower variants (e.g. half as fast, 1/4 as fast, etc.) from a periodic trigger signal (a “clock signal”). The A-160-1 is often supplemented with the A-161 Clock Sequencer, which requires the A-160-1 as a necessary basic module. But the A-160-1 can of course also be used as an audio … Read more
The A-152 Voltage Addressed Track & Hold / Switch module is by far the most flexible switching module presented here. It offers a bidirectional 8:1 or 1:8 switch that can be addressed via control voltage as well as switched sequentially via trigger signals (or switched back to the first level with a reset trigger). In … Read more
The A-157 Trigger Sequencer is a sequencer with 8 tracks, which, however, does not output adjustable control voltages like the A-155, but only trigger signals – comparable to the two trigger tracks on the A-155. To program when a trigger is to be sent and when not, there are no longer toggle switches like the … 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
(Almost) everyone has an A-140 ADSR Envelope Generator. For a good reason: the envelopes can be extremely “snappy” if necessary, but due to a three-stage “Time Range” switch very slow times are possible as well. The features of the module are solid and well thought-out standard: a gate and a retrigger input, three outputs for … Read more
