Arduino and AY-3-8910 – Part 4

After Part 3 I started to go back and add MIDI, and changed the waveform on the touch of a button, and then started to wonder if I could add envelopes and so on. And then it occurred to me, I didn't really need to re-implement my own synthesis library, I could probably write a custom … Continue reading Arduino and AY-3-8910 – Part 4 →

EuroRack 6HP Arduino Mozzi Module – Basic VCO

This is the first project based on my EuroRack 6HP Arduino Mozzi Module. It is loosely based on HAGIWO's Arduino Mozzi VCO Module. https://makertube.net/w/hnocMAhYkajd8nX2vwuR2u 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 some previous posts for the main concepts … Continue reading EuroRack 6HP Arduino Mozzi Module – Basic VCO →

EuroRack 6HP Arduino Mozzi Module

This project uses my EuroRack 6HP MCU Experimenter Module to implement HAGIWO's Arduino Nano based VCO. This post describes how to put it together and test the basic functionality. Future posts will look at some code that can run on the module (see the "Sample Applications" section). Warning! I strongly recommend using old or second hand … Continue reading EuroRack 6HP Arduino Mozzi Module →

ESP32 WROOM Mozzi Experimenter PCB Design

Before building my Educational DIY Synth Thing I was playing with the ESP32 WROOM dev boards I'd found and was thinking about doing some Mozzi experiments. This post started to document some of the things I'd found out about the boards, but never made it to a complete post. I've now gone back and finished off … Continue reading ESP32 WROOM Mozzi Experimenter PCB Design →

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 →
