Pi Pico PIO Poly Tone Step Sequencer – Part 2

In this project I've added some basic IO to the Pi Pico PIO Poly Tone Step Sequencer. https://youtu.be/a5Mkd0wnbzs 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 tutorials for the main concepts used in this project: MIDI, MicroPython … Continue reading Pi Pico PIO Poly Tone Step Sequencer – Part 2

Arduino Top Octave Generator

My previous experiments with Arduino tone() polyphony have led to a curious tangent, following some comments on a hackaday post featuring my original project that compared my project to Top Octave Generators.  This describes how I used the same principle to create a simplified (and not very accurate or useful) Arduino Top Octave Generator as … Continue reading Arduino Top Octave Generator

Arduino Tone Polyphony – Part 5

Ok, I thought I’d done with Arduino Polyphony for the time being, but something else came up today that I wanted to try. My post got a mention on the Hackaday blog and one of the comments has led me to a tweak that helps the tuning a little. https://youtu.be/lEaZhnjikfs Warning! I strongly recommend using old or … Continue reading Arduino Tone Polyphony – Part 5

Arduino Tone Polyphony – Part 4

In this final (for now) part of my Arduino Tone Polyphony project I'm returning to part 2 which was creating a stand-alone, full 12-note polyphonic tone keyboard with an Arduino Uno and committing it to an Arduino Shield using a proto-shield. Warning! I strongly recommend using old or second hand equipment for your experiments.  I am … Continue reading Arduino Tone Polyphony – Part 4

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

Arduino MIDI 7 Segment Controller – Part 2

As mentioned in my previous post,  the Arduino MIDI 7 Segment Controller is ripe for turning into a self-contained module.  To keep it all relatively small, I opted to build an add-on board for an Arduino Nano. Warning! I strongly recommend using old or second hand equipment for your experiments.  I am not responsible for any … Continue reading Arduino MIDI 7 Segment Controller – Part 2
