Toy Keyboard Matrix Decode with the Pi Pico

I'm always on the look out for discarded music keyboards that I might be able to do something with, so when I came across this thrown out in the street I claimed it to take a look. This shows how I used a Raspberry Pi Pico to decode the keyboard part and turn it into … Continue reading Toy Keyboard Matrix Decode with the Pi Pico

Vintage Phone USB MIDI Controller

This is the USB MIDI controller version of the Vintage Phone MIDI Controller.  As the USB MIDI support is much easier in CircuitPython than MicroPython, this is also a version of the keypad controller code for CircuitPython too. Warning! I strongly recommend using old or second hand equipment for your experiments.  I am not responsible for … Continue reading Vintage Phone USB 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

Keyboard MIDI Matrix Decode

Following on from my Keyboard Matrix Decode I've now added MIDI out!  So I have a full sized MIDI controller keyboard for the cost of a cheap Arduino Nano clone and a couple of passive components! https://youtu.be/kqcfxiKIzi4 Warning! I strongly recommend using an old or second hand keyboard for your MIDI experiments.  I am not responsible for … Continue reading Keyboard MIDI Matrix Decode
