ESP32 DAC Envelope Generator

I'm continuing my series of experiments with the ESP32 by considering how I might use the twin DACs onboard the WROOM module as a Lo-Fi, 8-bit envelope generator. I've not looked at envelope generation before, so this is a good excuse to see what it is all about. Important Note: This is NOT an envelope … Continue reading ESP32 DAC Envelope Generator →

ESP32 and Mozzi

I've been meaning to do something with the ESP32 for some time. I have some general ESP32-C3 devices, and a range of XIAO ESP32 (S2 and C3) devices too, but what I was particularly interested in was the original ESP32 as it includes two 8-bit DACs. This is my first set of experiments using a … Continue reading ESP32 and Mozzi →

Arduino Audio and MIDI Frameworks

I've been collecting bookmarks for interesting Arduino audio projects for a while now, and having now played with the XIAO SAMD21 I started looking back over my list for other things to try. One thing that occurred to me is that there are a now a number of more powerful audio frameworks available for a … Continue reading Arduino Audio and MIDI Frameworks →

XIAO SAMD21, Arduino and MIDI – Part 3

In this post I wire up the DAC and start up Mozzi using my Arduino Multi-pot Mozzi FM Synthesis on the Seeedstudio XIAO SAMD21 board (previously known as the Seeeduino XIAO). Previous parts in this series: Part 1 - Introduction to the XIAO SAMD21 and some projects to get started. Part 2 - Looking at accessing … Continue reading XIAO SAMD21, Arduino and MIDI – Part 3 →

Arduino “Make Your Uno” Synth – 6 – MIDI Mozzi FM Synth

Putting together everything I have so far, this presents a basic MIDI controlled Mozzi FM synth. The full index of projects and my personal build notes can be found here: Arduino “Make Your Uno” Synth. This post contains the following experiments: MIDI Mozzi FM Synth Further Mozzi MIDI Experiments https://youtu.be/clG0iOgls-Q Warning! I strongly recommend using old … Continue reading Arduino “Make Your Uno” Synth – 6 – MIDI Mozzi FM Synth →

Arduino “Make Your Uno” Synth – 2 – Mozzi Experiments

Tones was the obvious first choice for some experiments, but I've now jumped straight to Mozzi experiments as the second suggested sketch on the Arduino tutorial is a Mozzi sketch. Otherwise I'd have probably saved this for a little later, but here are some Mozzi experiments you can do with your board right away. Of … Continue reading Arduino “Make Your Uno” Synth – 2 – Mozzi Experiments →

This is the build guide for my Arduino Nano Mozzi Experimenter Shield PCB. Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for any damage to expensive instruments! These are the key Arduino tutorials for the main concepts used in this project: Arduino Multi-pot Mozzi FM Synthesis Mozzi … Continue reading Arduino Nano Mozzi Experimenter Shield PCB – Part 2 →

Arduino Multi-pot Mozzi FM Synthesis – Revisited

I've been watching how people have been getting on with the Arduino "Make Your Uno" kit in which you build up your own Arduino Uno and a five-pot synth shield. I've love to get one, but I really can't justify the cost as I don't need the soldering practice (well, I might, but not on … Continue reading Arduino Multi-pot Mozzi FM Synthesis – Revisited →
