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 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

Pi Pico PIO Poly Tone Step Sequencer

In the next part of my messing around with the Raspberry Pi Pico PIO polyphonic tones, I've paired it up with my Pi Pico Keypad MIDI Step Sequencer using my Pimoroni RGB Keypad. In part 2 I add some MIDI controllers. https://youtu.be/JJSOUhSP038 Warning! I strongly recommend using old or second hand equipment for your experiments.  I … Continue reading Pi Pico PIO Poly Tone Step Sequencer

Pi Pico PIO Poly Tone MIDI “Pack”

This is a simple "pack" design for the Pi Pico PIO Poly Tone Keyboard providing 8-note tone-style polyphony with MIDI in functionality. 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 Arduino tutorials for the main concepts used … Continue reading Pi Pico PIO Poly Tone MIDI “Pack”

Raspberry Pi Pico MIDI “pack” Interface

Having now done both MIDI In and MIDI Out for the Raspberry Pi Pico, and having seen the Adafruit MIDI Feather Wing and the design for "packs" ("shields" in Arduino speak or "wings" in Adafruit Feather speak) from Pimoroni, I wanted a convenient equivalent for my MIDI In and Out and this is the result. … Continue reading Raspberry Pi Pico MIDI “pack” Interface
