Inroduction Greetings, from the southern hemisphere! Today we continue our exploration of microcontrollers in the eurorack environment, focusing on the critical aspect of receiving external signals. Why is this important? Well, these signals, whether from potentiometers, buttons, or other modules, serve as our bridge to interact with the programs running on the microcontroller. There is plenty of material out there on hooking up potentiometers and buttons out there. Trust me you don’t have to look far.

Introduction Hey, what’s up? Juan here, and we’re diving into the second part of our Dual ADSR/VCA combo module. If you missed the first part, check this link for a recap. Today, we’re not just wrapping up the project; we’re reflecting on the journey. Build Highlights Alright, let’s kick things off with a speedy recap. As you recall we combined an ADSR circuit together with a VCA circuit so that we can run audio and a gate signal in order to shape the audio signal coming out of the module.

Introduction Hello again! As we gear up for 2024, I’ve got some exciting projects in the pipeline. While I’m waiting for parts to arrive, I thought it would be a great time to help you set up your microcontroller development environment. Having a robust Integrated Development Environment (IDE) is crucial for efficient software development. An IDE, much like our homes, provides us with essential tools and features that streamline our workflow.

Dual ADSR / VCA Combo! (Part 1) Introduction Hey Kittehs! I’ve been knee-deep in home improvement tasks, but today, we’re starting another analog circuit for eurorack. My system is missing some very important pieces. Can you guess? Yup, I’m missing an ADSR and you know what they say you can’t ever have enough VCAs. And since the VCAs I have are mostly passive I figured our module will be a combination of a VCA and ADSR with additional inputs and outputs to use them independently.

Why I use ferrite beads in my modular synth circuits. Eurorack modules rely on intricate circuitry and electrical components to eventually create something audible. Sometimes we use those modules to create pleasing sounds and other times for perhaps the complete opposite. Regardless, the result is a translation of what we can think of and how we may recreate them with our tools. Audio artifacts which are introduced either by environmental noise or radio frequencies, is rarely something we want in our mixes so, we engineer to reduce nose as much as possible.

Introduction For this latest entry I’m going to keep it short and sweet since most that could be said about this project already has been said. That being said, let’s go over what’s in the video. Changes to the schematic…. It’s not uncommon to build something and then discover that tweaking it yields better results. And that’s what happened. Here is quick list. Modified the inverted envelope so it receives signal from env2 instead.
