Microcontrollers: G8R!

Hey, everyone! I promised you a project utilizing what we’ve learned so far in our microcontroller series. So today, I’m thrilled to introduce you to my latest DIY Eurorack module creation: G8R. In this video, we’ll dive into the hardware and circuitry behind G8R, explore its features, and discuss the possibilities it offers for your modular synth setup. Overview of G8R G8R is a versatile Eurorack module focusing on gate and trigger events and designed to add MIDI integration to your modular synth rig.

Introduction to MIDI with Arduino

Today’s video covers an essential topic we haven’t addressed yet: MIDI with microcontrollers. We’ll explore a high-level overview of MIDI, how to wire up circuits for MIDI input and output, and configuring the Arduino MIDI.h library for use with an STM32 BluePill microcontroller. Let’s dive in! 2. What is MIDI? MIDI, or Musical Instrument Digital Interface, is a technical standard that facilitates communication between electronic musical instruments, computers, and other devices.

KiCAD 7 custom footprints

Sometimes we find ourselves working on a schematic and find that we don’t have a footprint for the part or component we are using. So we think, OK someone elese probably ran into this issue so why not check the internet? Why not? If someone else has done it why re-invent the wheel right? So, you find your part, place your component and then ship your files for manufacturing. A week later you get your boards only to find that the footprint is off.

Microcontrollers: Gate and trigger output signals

Introduction Hey, friends! Welcome back to our microcontroller adventure. In this episode, we’re diving into the world of output signals. We’ve already explored input considerations, and now it is time to start looking at output signals. Today we will cover gates, triggers and some simple LEDs. If you are wondering what these are: Gates and triggers are control signals used in electronic music to initiate and control events such as note playback, envelope shaping, and rhythmic patterns.


UMIDI A couple of years ago, I made a module for my eurorack that allowed me to use my Korg ES2 sampler to trigger drum modules. The idea was that it could have a TRS MIDI input and gate outputs. The module has been incredibly useful, but I want more! The Teensys are not cheap, and this project used a Teensy 2.0++ so I thought why not use an STM32 Blue Pill instead and do it at a fraction of the cost.

Microcontrollers: Input Signals

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.
