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
Zynthian Revisited
After having a quick play with Zynthian just over a year ago, I've always had it in the back of my mind to make a "proper" Zynthian box with its own interface and controls. This is the first part of that project, hooking it up to a touchscreen and some rotary encoders. In Part 2 … Continue reading Zynthian Revisited
Arduino Touchscreen X-Y MIDI Controller – Part 2
Whilst being able to use a cheap touchscreen with a DIY shield gets me so far, there are a number of cheap touchscreen shields around and I've had one for a while, but not managed to really get it going. I thought it was perhaps about time to see what I could do, so I … Continue reading Arduino Touchscreen X-Y MIDI Controller – Part 2
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
An Even Tempered Pico
I was having a bit of a discussion about tuning and temperament in music with Midi_in_out on Twitter, after they posted the latest update to their MIDISID project and we got on to talking about polyphony. I know the general theory behind natural harmonics vs the compromise that is the even tempered scale we use … Continue reading An Even Tempered Pico
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”
Arduino Multi MIDI Merge – Part 2
I've built a number of MIDI merge projects so far (for Arduino and Pico), but they've always taken a relatively simple approach to the merge. They had all ensured that MIDI messages won't be corrupted as they are merged - i.e. only complete messages will be passed on - but they've done nothing to interpret the … Continue reading Arduino Multi MIDI Merge – Part 2
Raspberry Pi Pico SysEx “Librarian”
I've seen a few dedicated units for sending and managing patches for older synths and whilst they look really neat, I thought it would be worth me having a go and seeing what I could do myself. This is my first attempt at pretty much the simplest hardware "patch librarian" I could imagine - it … Continue reading Raspberry Pi Pico SysEx “Librarian”
