Raspberry Pi Pico MIDI Module PCB

I've now built several DIY Raspberry Pi Pico MIDI interfaces, and despite several hints via social media, no-one has come forward to make me a simple MIDI interface module, so I've decided to have another go at making a PCB myself. Update: Find the Build Guide here: Raspberry Pi Pico MIDI Module PCB - Part 2 … Continue reading Raspberry Pi Pico MIDI Module PCB →

Zynthian Revisited – Part 2

Having prototyped the idea of a hardware user interface with my Zynthian in Zynthian Revisited this posts develops a DIY IO board for use with a Raspberry Pi to make connecting everything a little neater. If I like it I might see if I can turn it into a custom PCB. Eventually I'd like a … Continue reading Zynthian Revisited – Part 2 →

Arduino Uno Dual Merge MIDI “Shield” – Part 3

Having been sitting and waiting for my Seeedstudio Fusion order from the board designed in part 2, three weeks later - it's here! So this is by way of an assembly guide and review of the design and production. Warning! I strongly recommend using old or second hand equipment for your experiments. I am not … Continue reading Arduino Uno Dual Merge MIDI “Shield” – Part 3 →

Arduino Touchscreen X-Y MIDI Controller

I have a list of other projects I'd like to use my cheap touchscreen MIDI controller for. For details see the original discussion here: Arduino Touchscreen MIDI Controller. In this project I turn it into an "X-Y" controller - essentially a two-dimensional potentiometer. Moving in the Y direction changes one value and moving in the X … Continue reading Arduino Touchscreen X-Y MIDI Controller →

Arduino Uno Dual Merge MIDI “Shield” – Part 2

I've been meaning to have a try at PCB design for a while. I'd like to add it to the list of things I'm amateurly enthusiastically ignorant about. I've not seen anything like my Arduino Uno Dual Merge MIDI “Shield” available anywhere but it is built of individual designs I am very familiar with, so I … Continue reading Arduino Uno Dual Merge MIDI “Shield” – Part 2 →

Arduino Uno Dual Merge MIDI “Shield”

Having spent some time now playing with a range of MIDI merge options, one final thing I wanted to do was have a "merge shield" that could quickly turn an Arduino Uno into a simple two-in, one out MIDI unit. Warning! I strongly recommend using old or second hand equipment for your experiments. I am … Continue reading Arduino Uno Dual Merge MIDI “Shield” →

“Bare Metal” Raspberry Pi MiniDexed DX7 – Part 2

This is a continuation of my exploration of MiniDexed. In part 1 I built a basic breadboard version. In this part, I've built a DIY "MiniDexed HAT" for a 40-way GPIO Raspberry Pi. Update: There is also now a custom PCB too: MiniDexed Raspberry Pi IO Board. https://youtu.be/7gKDfDWLHzw Warning! I strongly recommend using old or second … Continue reading “Bare Metal” Raspberry Pi MiniDexed DX7 – Part 2 →

Arduino MIDI Telephone Ringer – Part 3

The last thing I wanted to do with my (dual) telephone ringer, well, besides trying to find six more phones and get an octave's worth of ringing, was put my dual-ringer into a box. This shows how I managed that. In part 1 I talked about the basic hardware and approach. In part 2 I … Continue reading Arduino MIDI Telephone Ringer – Part 3 →

Arduino Nano MIDI IN “Shield”

This is "yet another" Arduino MIDI Interface, after all I don't think I've built one for a few months now... Actually I need this for another project, but thought it worth of writing up on its own first. A Nano "shield" type MIDI In might be useful elsewhere too! Warning! I strongly recommend using old … Continue reading Arduino Nano MIDI IN “Shield” →

Raspberry Pi Pico Multi MIDI Router – Part 3

The obviously missing part of my Raspberry Pi Pico Multi MIDI Router is the use of USB MIDI. The Pico should support both USB host and device functionality, but I think you need to get into the C software development kit to do that properly, something I've not looked at yet. One of the easiest ways … Continue reading Raspberry Pi Pico Multi MIDI Router – Part 3 →
