Modular

An analog, semi-modular, patchable synthesizer you can build yourself The Polykit X1 is a DIY semi-modular synthesizer that pairs a single Polykit-X voice card with a dedicated …

This Arduino based module let’s you quantize and hold a given control voltage. There are controls for selecting different scales and transposing a note. The module can either …

This clock divider is built around the CD4024 CMOS 7-stage binary counter. It divides an incoming clock signal by powers of two, providing six simultaneous outputs. It’s a compact …

The Eurorack Sequencer is a straightforward, flexible 8-step sequencer designed around the Arduino Nano. It offers a hands-on approach to pattern creation with plenty of CV control …

This spring reverb module is part of my Eurorack series. It drives a reverb tank and has two inputs, control for dry/wet to blend between original and processed signal, and a …

This Eurorack ring modulator allows the multiplication/amplitude modulation of two signals. There are two center-tapped mini transformers and a ring of four diodes, which form this …

The Eurorack output module gives you a versatile option to either connect your modular to a mixer or amplifier, or to drive some headphones with it. There are controls to attenuate …

This module lets you safely and neatly bring 12V AC power into your modular case. It features a barrel jack connector, an on/off switch, and a power status LED, making it easy to …

This voltage controlled oscillator is part of my Eurorack series. It outputs a saw and square signal, and its frequency is controlled by a 1V/Octave control voltage. There are CV …

This filter is part of my Eurorack series. The design is based on the Steiner-Parker diode filter, and I stripped it down to a minimal set of components while keeping its …
