Build an MinEQ Module!

Hosted by Żłob Modular
Sunday, Sept 7 @ 2pm
Difficulty: Beginner

The MinEq is a 2hp 3 Band Equalizer Eurorack Module with a rectified clipping feedback circuit which produces a wide range of harmonic distortion, interactive self-oscillating, pseudo ring modulation, and richer filter-esque timbres based on the input and knob positions.

This hybrid Baxandall circuit provides +/- 20dB~ of boost or cut control over the Low, Mid and High frequency bands of an audio input. The frequency bands are centered near 30Hz(Low), 1kHz(Mid), and 10kHz(High). With all the potentiometers at noon, the MinEq passes the signal relatively unaltered.

The Panel is reversible, one side with graphics and soulless side with less graphics (not pictured).

Learn to solder! Żłob Modular will teach you basic soldering techniques and lead you through building the Attenumixer module.

Builder's Choice:
Etch or Easy Ei8ht Sequencer!

Hosted by Modular for the Masses
Saturday, Sept 7 @ 11am
Difficulty: Easy

Build Etch, a Bit Crusher and More!

Etch is a low fidelity digital signal processing Eurorack module that selectively removes signal quality vertically (bit crushing) or horizontally (sample rate reduction). This creates vertical or horizontal lines in the signal, like an Etch-a-Sketch! The results are displayed on a simplified oscilloscope.

Both parameters can be controlled with a control voltage, as well as a third parameter, a low-pass resonant filter.

In addition to being an effects module, there is a quantizer mode, featuring many scales and options the designer of the hardware and workshop host (Juanito, I'm the one writing this) doesn't even understand. For a better explanation of the CV mode, visit the project's Github: https://github.com/TylerK07/Etch

A feature Juanito understands and loves is the "loop" mode. It can be an unusual form of granular synthesis, which takes a section of the incoming signal and loops it quickly, up to audio rate. It has the ability to accept portions of the still-incoming audio signal to morph the waveform of the loop. Tweaking the knobs in this mode is very engaging.

The microchip is an AVR128DA28, which is common, easy to code for, and the analog electronics are versatile, allowing for both audio signal processing and control voltage processing.

The surface mount components are all pre-assembled, so no advanced soldering skills will be necessary.

Easy Ei8ht Sequencer Module Build

The EasyEi8ht trigger performance sequencer returns with an updated panel and simplified construction.

This module is designed from the ground up to be extremely simple to use. It features eight channels, ludicrously long pattern lengths, and Cherry MX style mechanical key switches (three different types will be available to choose from). It can be self-clocked or accept an external clock. It features downbeat-agnostic swing, even if the external clock doesn't have swing. The project is open-source, the code was developed in the Arduino IDE, so the module is ready for DIY firmware.

The build has all the surface-mount components pre-assembled. Some care with order-of-assembly will need to be taken, but advanced soldering skills won't be necessary. The module is 14HP

Build a Voltage Controlled Slope Generator Module!

Hosted by Modular for the Masses
Saturday, Sept 6 @ 2pm
Difficulty: Easy

VCSlopeBuild

Build your own voltage controlled slope generator module with guidance from Juanito!

Here's yet another slope generator! This 8hp Eurorack module started with a faithful copy of a Serge voltage-controlled slope generator with a few tweaks and two added features. The slope generator is the modular world's most versatile device, it can be a VCO, an LFO, an envelope generator, envelope follower, a transient detector, a pulse delay, an audio filter, and more! These guys work best in multiples which is why they so often appear as DualUSGs or Maths etc. This particular slope generator gives the user voltage control over the rise and fall shape, exponential voltage control over the rate (labelled V/Oct, but it's not calibrated or temperature compensated), it has an attenuverter at the end of the signal chain, and a gate output that goes high when the signal is falling. The shape controls have been made more sensitive than Serge's design, and tweaked to make it easy to get a nice linear slope at the 12 o'clock position.

Build an Attenumixer Module!

Hosted by Żłob Modular
Saturday, Sept 6 @ 11am
Difficulty: Beginner

The Attenumixer is a 4hp 3 channel Passive Attenuator and Mixer for eurorack format modular synthesizers.

Each channel is normalled to the sum(VI) so it can be used as a 2 channel mixer and 1 channel attenuator, or a 3 channel mixer, or as 3 separate attenuators. Normalization to the sum is broken by inserting a jack into the outs of channels I-III. The Attenumixer works well with both cv and audio, although the potentiometers have a linear response. Since the module is passive there will be signal loss at the sum out.

The module comes with a double sided panel one side is classic with the traditional graphics and the reverse side is soulless with no graphics, only text(not pictured).

Learn to solder! Żłob Modular will teach you basic soldering techniques and lead you through building the Attenumixer module.
