Raspberry Pi Pico Reversible MIDI Out

I wanted a quick "just plug in and use it" MIDI out for my Pico, but in a slightly simpler format than my Raspberry Pi Pico MIDI "pack" Interface, so popped this one together as an alternative. Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for any … Continue reading Raspberry Pi Pico Reversible MIDI Out →

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 →

DIY MIDI Interfaces

This page is a mixture of beginner and advanced, DIY options covering MIDI in (receive), MIDI out (send), and USBMIDI to MIDI conversion for non-Arduino like microcontrollers. Here are some other pages of interest: Ready-Made MIDI Modules - a range of modules for "ready to go" MIDI IN and OUT for both 5V and 3V … Continue reading DIY MIDI Interfaces →

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” →

Pi Pico Keypad MIDI Step Sequencer

As soon as the Raspberry Pi Pico came out accompanied by the Pimoroni Keypad, people started making MIDI controllers with it. So far, most of the ones I've seen have used the USB MIDI library from Adafruit for Circuit Python, but I wanted to get some "real MIDI" out of it, so I've hooked one … Continue reading Pi Pico Keypad MIDI Step Sequencer →

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 →

Pi Pico PIO Poly Tone MIDI Keyboard

Following on from the Pi Pico PIO Poly Tone Keyboard here it is combined with one of the DIY MIDI Interfaces to give an eight note polyphonic MIDI tone module based on the Raspberry Pi Pico. In a follow-up post I develop a "pack" MIDI interface. https://youtu.be/uscUlgJ-NBk Warning! I strongly recommend using old or second hand equipment … Continue reading Pi Pico PIO Poly Tone MIDI Keyboard →

Pi Pico PIO Poly Tone Keyboard

One of the obvious use-cases for the Raspberry Pi Pico's Peripheral I/O system (PIO) is in generating simple tones. Ben Everard from Hackspace Magazine did exactly that. You can read the full tutorial here or in Hackspace Magazine Issue 40. All the code for his PIOBeep.py can be found on GitHub here, and he leaves … Continue reading Pi Pico PIO Poly Tone Keyboard →
