Arduino Mozzi Experimenter Shield PCB

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 →

Raspberry Pi Pico MIDI Channel Muter

This project uses a Pimoroni RGB Keypad with a Raspberry Pi Pico to create 16 "mute" switches for MIDI, one for each MIDI channel. https://youtu.be/8KiXT91sSk8 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 tutorials for the … Continue reading Raspberry Pi Pico MIDI Channel Muter →

Arduino Stackable TRS MIDI Interface

As Arduino MIDI Interfaces are so common in most of my builds, I decided to build a "stackable" module.  This was partly triggered by the release recently of the official Arduino "Make Your Uno" kit which comes with a synth shield you can build.  But it doesn't have MIDI so I thought something like this would … Continue reading Arduino Stackable TRS MIDI Interface →

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 →

Raspberry Pi Pico MIDI Splitter (TTL) – Part 2

This is the build guide for my Raspberry Pi Pico MIDI Splitter (TTL). Tutorials used in this project: Raspberry Pi Pico MIDI Channel Router Raspberry Pi Pico Multi MIDI Router – Part 4 Notes on KiCad for PCB design: Arduino Uno Dual Merge MIDI “Shield” - Part 2 If you are new to microcontrollers, see the Getting Started … Continue reading Raspberry Pi Pico MIDI Splitter (TTL) – Part 2 →

Raspberry Pi Pico Dual MIDI Carrier – Part 2

This is the build guide for my Raspberry Pi Pico Dual MIDI Carrier to support my dual-MIDI interfaces for a Raspberry Pi Pico designed by @VE7FIM from Twitter.  Although designed largely for my own personal use with that specific dual-MIDI module, it could still also be used to link to several off-the-shelf MIDI modules if required. If … Continue reading Raspberry Pi Pico Dual MIDI Carrier – Part 2 →

Zynthian Revisited – Part 4

This is the build guide for my Zynthian IO Board 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 tutorials for the main concepts used in this project: Zynthian Revisited Zynthian Revisited - Part 2 Zynthian … Continue reading Zynthian Revisited – Part 4 →
