Introduction So, I was messing around with a project using those endless pots that everyone loves (you know, the ones that turn and turn and turn and never stop turning). The goal was to use the Raspberry Pi Pico and the MCP3204 ADC to read the pots’ values. Simple enough, right? Well, turns out the universe had other plans. While everything worked perfectly fine on my trusty Bluepill using the Arduino framework, when I moved the code over to the Pico, things went… not so smoothly.

Howdy, folks! Today’s post might not be the most thrilling, but after spending days wrestling with this, I figured it deserved a little attention… Why This Exists I’ve mentioned before how I like the Arduino framework but dislike the IDE. PlatformIO has been a game-changer for the hardware I’ve used so far, including Teensy, Arduino, and BluePill boards (for the most part). Recently, I decided to dive into the DaisySeed because it seems like the best option for audio developers tackling DIY projects.

In this post, we will discuss how to get an analog signal out of our microcontroller. To produce a control voltage for our modular synth, we need a circuit that can convert a digital value—like an audio sample, MIDI CC, or mapped value—into an analog signal. This type of circuit is called a digital-to-analog converter, or DAC. There are many types of DACs, and choosing the right one can be a bit intimidating.

Hey, everyone! This video is long overdue, and I apologize for the delay. I’ve been away tending to family obligations abroad and unfortunately, I managed to kill my laptop while away. My laptop has now been fixed but all the material I had already prepared was lost so I am re-recording this for you all. I’m going to do things a little bit differently since the first time around it was more than I could chew.

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.

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.
