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 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 →

Arduino MIDI R2R Digital Audio – Part 2

My Arduino MIDI R2R Digital Audio has been used, pretty much unchanged, in my Lo-Fi Orchestra performances since my first recording, but I've always had a bit of an irritating "Lo-Fi click" when starting and stopping notes.  But whilst I've tinkered a little, mostly I've just lived with it, but now I'm finally taking a look. … Continue reading Arduino MIDI R2R Digital Audio – Part 2 →
