Following on from my Arduino Audio Experimenter Shield PCB here is another shield, this time more optimised for experiments with the Mozzi synthesis library for Arduino. Update: Build notes are now available here: Arduino Mozzi Experimenter Shield PCB – Part 2 Warning! I strongly recommend using old or second hand equipment for your experiments. I am not … Continue reading Arduino Mozzi Experimenter Shield PCB

Arduino Nano Multi-tone or PWM PCB
My latest Lo-Fi Orchestra piece is calling out for more brass and woodwind, so I'm thinking about ways to expand the setup. One thing I always wanted to improve on is the banks of Arduino Nanos I'm currently using for brass and strings. This PCB design will hopefully provide a much neater solution to my … Continue reading Arduino Nano Multi-tone or PWM PCB
Arduino Audio Experimenter Shield PCB
I have a number of Arduino projects that allow for some kind of synthesis to be output via a digital to analog conversion process. This PCB brings three of those methods together into a single shield to support a range of experiments. Warning! I strongly recommend using old or second hand equipment for your experiments. … Continue reading Arduino Audio Experimenter Shield PCB
Yet Another Toy Keyboard USB MIDI Controller – Part 2
So this follows on from the first part and adds MIDI, some buttons to control the keyboard and gives it a voice of its own. https://youtu.be/NUaCPR0LRTM Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for any damage to expensive instruments! If you are new to microcontrollers, … Continue reading Yet Another Toy Keyboard USB MIDI Controller – Part 2
Raspberry Pi Zero PWM Audio Interface
The Raspberry Pi Zero (I'm talking about V1 here, with no wireless. At the time of writing, V2 has just been released and I've yet to have a play with that!) has capabilities on par with the first generation "full" Raspberry Pi, so I was keen to try my “Bare Metal” Raspberry Pi Synth on one. … Continue reading Raspberry Pi Zero PWM Audio Interface
“Bare Metal” Raspberry Pi Synth – Part 3
This project uses an off-the-shelf analog IO board for the Raspberry Pi for my "bare metal" Raspberry Pi v1 (model B) synth. Full index of posts in this series: Part 1: The basics of setting up an environment to build a “bare metal” Raspberry Pi synth application. Part 2: Adding potentiometer controls via an MCP3008 … Continue reading “Bare Metal” Raspberry Pi Synth – Part 3
“Bare Metal” Raspberry Pi Synth – Part 2
This post builds on part 1 and starts to add some IO handling code and simple synthesis code to the bare metal Raspberry Pi experiments. Full index of posts in this series: Part 1: The basics of setting up an environment to build a “bare metal” Raspberry Pi synth application. Part 2: Adding potentiometer controls … Continue reading “Bare Metal” Raspberry Pi Synth – Part 2
The Complete Lo-Fi Planets
Inspired by the legendary Tomita, the Lo-Fi Orchestra presentation of Gustav Holst's Planets Suite is now complete. The original Lo-Fi Orchestra project started off as an attempt to bring a range of my "Simple DIY Electronic Music Projects" together to "perform" a single piece. After a number of initial performances, I decided to take the … Continue reading The Complete Lo-Fi Planets
Lo-Fi Orchestra – Neptune from The Planets
Inspired by the legendary Tomita, the Lo-Fi Orchestra presents the final piece, Neptune, from Gustav Holst's Planets Suite. This features the Adafruit Feather MIDI, Music and LEDs on the celesta, the Arduino MIDI VS1053 Synth as the 'harp', and the Raspberry Pi, Clumsy MIDI and MT32-Pi using the Fluidsynth soundscape as the voices. This has been programmed … Continue reading Lo-Fi Orchestra – Neptune from The Planets
Auduino Slider Waveform Granular Synthesis
Now I have a version of the Auduino that will use a wavetable as the grain for the granular synthesis, I can start some alternative experiments, so first of all I thought I would try to use my slider potentiometers to build the wavetable. https://youtu.be/HABkDbIHvO8 Warning! I strongly recommend using old or second hand equipment … Continue reading Auduino Slider Waveform Granular Synthesis
