A-160-5 Voltage Controlled Clock Multiplier / Ratcheting Controller

Ratcheting controllers are still somewhat unusual tools in the modular world. Tangerine Dream already used them to create exciting sequences almost 50 years ago. What does a ratcheting controller do? Basically we have the opposite of a clock divider (such as the A-160-2): An incoming clock signal is multiplied, if possible in such a way … Read more

A-110-6 Trapezoid Quadrature Thru Zero VCO

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

A-147-2 Voltage Controlled Delayed Low Frequency Oscillator

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

A-168-1 PWM Generator

The A-168-1 is a small auxiliary module that generates a square or pulse oscillation that can be modulated in width for LFOs or VCOs without a square/pulse. This is an interesting feature for LFOs in particular, since almost all LFOs can generate a fixed, symmetrical square wave (at least the A-146 is capable of manually … Read more

A-110-4 Quadrature Thru Zero VCO

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

A-160-2 Clock/Trigger Divider II

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

A-133-2 Dual VC Polarizer

The A-133-2 is a dual voltage controlled polarizer, meaning its input signals (audio or control voltages) can be amplified like a traditional VCA. With a negative control voltage or a corresponding manual setting, the input signals are amplified in inverted form. An input, a control voltage input, an output, as well as a manual controller … Read more
