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
Arduino MIDI Telephone Ringer – Part 2
Following on from part 1, I've added BT style sockets and upgraded the ringer to ring two phones. Polytelephony if you will. In part 3, I switch to an Arduino Nano and put all the circuitry into a box. https://youtu.be/IBBd9z4hKYw Warning! I strongly recommend using old or second hand equipment for your experiments. I am … Continue reading Arduino MIDI Telephone Ringer – Part 2
Arduino MIDI Telephone Ringer
One thing I love about those vintage rotary telephones is the characteristic ring. But making them do that outside of being plugged into the PSTN isn't easy. But I wanted to see if I could make it work over MIDI, so this is my approach. In part 2 I add some BT style sockets and … Continue reading Arduino MIDI Telephone Ringer
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
Yet Another Toy Keyboard USB MIDI Controller
Ok, I admit, there is a bit of a theme to some of my projects, but this keyboard that I found in a charity shop was such a dinky thing that I had to do Just One More (TM). Warning! I strongly recommend using old or second hand equipment for your experiments. I am not … Continue reading Yet Another Toy Keyboard USB MIDI Controller
Vintage Rotary Phone MIDI Controller – Part 7
Having built my adaptor into a small box, I've gone back to add a mode button so I can include all the different applications into a single sketch. This builds on the previous parts in this series. Part 1 - Understanding the telephone hardware and interfacing to an Arduino. Part 2 - Decoding the rotary … Continue reading Vintage Rotary Phone MIDI Controller – Part 7
