Vintage Phone MIDI Controller

I happened across a pretty dirty Doro x20 push-button phone in some very 70s colours in my garage as part of a clear out and thought it might make a fun MIDI controller.  My first experiment uses a Raspberry Pi Pico (in "sawn-off" mode - see later!). In this follow-up post, I turn the phone … Continue reading Vintage Phone MIDI Controller

Pi Pico MIDI Matrix Decode – Part 4

I'd left the Pi Pico MIDI Matrix Decode project essentially working but with a ghosting multiple keypresses problem.  I was just going to let it go, but then I decided I just couldn't leave it there, so I had to take another look. Warning! I strongly recommend using old or second hand equipment for your experiments.  … Continue reading Pi Pico MIDI Matrix Decode – Part 4

Pi Pico MIDI Matrix Decode – Part 3

Expanding on the Pi Pico MIDI Matrix Decode project to create a basic four octave keyboard.  There are some limitations with this approach though, so be sure to read on before trying to build one yourself (or skip over to Part 4 to read about the solution). https://youtu.be/Wc3dhsPsm0w Warning! I strongly recommend using old or … Continue reading Pi Pico MIDI Matrix Decode – Part 3

Pi Pico MIDI Matrix Decode – Part 2

This is taking the solderless breadboard "keyboard" from my Pi Pico MIDI Matrix Decode project and committing it to stripboard. In part 3 I expand it to four octaves. 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 … Continue reading Pi Pico MIDI Matrix Decode – Part 2

MIDI, CircuitPython, CPX and Pi Pico

Inspired by my initial play with the Raspberry Pi Pico and MicroPython, I wanted to also see what I could do with both the Micro:bit and my Adafruit Circuit Playground Express MIDI-wise too.  Both are 3.3V boards and both can run a variant of MicroPython - either native or using the Adafruit version - CircuitPython. … Continue reading MIDI, CircuitPython, CPX and Pi Pico

MIDI, MicroPython and the Raspberry Pi Pico

It was an exciting day on Thursday this week on Twitter.  I was able to watch the release of the Raspberry Pi Foundation's new microcontroller board, the Raspberry Pi Pico and it looks like it will have lots of features that will be of interest for Simple DIY Electronic Music Projects. And the best bit?  … Continue reading MIDI, MicroPython and the Raspberry Pi Pico
