Having played with MiniDexed a little now, I really wanted something that could select the different banks of voices for me. This is how I've used a Raspberry Pi Pico as a set of "bank select" switches, but the switches could be used to send any MIDI change control messages. https://youtu.be/if0iKuHCkE4 Warning! I strongly recommend … Continue reading Pi Pico MIDI Button Controller

“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
“Bare Metal” Raspberry Pi MiniDexed DX7
One project I've had my eye on for some time is Dexed: "Dexed is a multi platform, multi format plugin synth that is closely modeled on the Yamaha DX7". More specifically I noticed there was a version for the Teensy called microDexed that I really wanted to try; that it is also one of the synth … Continue reading “Bare Metal” Raspberry Pi MiniDexed DX7
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
CircuitPython USB to Serial MIDI Router
I've indirectly used USB and Serial MIDI with CircuitPython a few times now, but haven't explicitly shown how to use it as a simple USB (device) to serial MIDI converter. This project shows how to do that. Any CircuitPython device should be usable like this, but I've used this as an excuse to do something … Continue reading CircuitPython USB to Serial MIDI Router
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 Serial MIDI Program and Control Messenger
I believe I have all the components of both sending and receiving MIDI Program and Control messages over the full range of serial interfaces from previous projects, but I'm not sure I've ever written it down in those terms. So this project aims to put that right! Warning! I strongly recommend using old or second … Continue reading Arduino Serial MIDI Program and Control Messenger
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
