Raspberry Pi Pico Multi MIDI Router – Part 3

The obviously missing part of my Raspberry Pi Pico Multi MIDI Router is the use of USB MIDI. The Pico should support both USB host and device functionality, but I think you need to get into the C software development kit to do that properly, something I've not looked at yet. One of the easiest ways … Continue reading Raspberry Pi Pico Multi MIDI Router – Part 3 →

CircuitPython USB to Serial MIDI Router

I've indirectly used USB and Serial MIDI with CircuitPython a few times now, but haven't explicitly shown how to use it as a simple USB (device) to serial MIDI converter. This project shows how to do that. Any CircuitPython device should be usable like this, but I've used this as an excuse to do something … Continue reading CircuitPython USB to Serial MIDI Router →

Raspberry Pi Pico MIDI Pedal Keyboard

Quite a number of years ago, I found an old set of organ pedals and MIDI'd them up by the crude method of wiring the pedal switches onto the connectors for the keys of an old Amstrad MIDI keyboard... It was the technology and expertise I had at the time! I stumbled across them a … Continue reading Raspberry Pi Pico MIDI Pedal Keyboard →

Raspberry Pi Pico I2C MIDI Interface – Part 4

For this final (for now) part of my experimenting with my Raspberry Pi Pico I2C MIDI Interface, I've set it up to talk to multiple Arduino's, each with a speaker to act as an I2C MIDI "tone module". In part 1, I tested the concept of a Pico I2C MIDI interface. In part 2, I … Continue reading Raspberry Pi Pico I2C MIDI Interface – Part 4 →

Raspberry Pi Pico I2C MIDI Interface – Part 3

Continuing my experiments with my Raspberry Pi Pico I2C MIDI Interface, one comment on Twitter asked about latency, so I thought I'd try to see if it was possible to measure how long it took for a complete round trip of a MIDI message from an Arduino through the Pico, back out over I2C to … Continue reading Raspberry Pi Pico I2C MIDI Interface – Part 3 →

Raspberry Pi Pico I2C MIDI Interface – Part 2

Following on from Raspberry Pi Pico I2C MIDI Interface this post looks at how to use the I2C MIDI layer with the Adafruit MIDI library for CircuitPython. 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 … Continue reading Raspberry Pi Pico I2C MIDI Interface – Part 2 →

Raspberry Pi Pico I2C MIDI Interface

I thought it was time to see if I could add a Raspberry Pi Pico to my Arduino I2C MIDI setup. This is the first step to getting them talking MIDI over I2C using Circuitpython. In part 1, I'm testing the concept of a Pico I2C MIDI interface. In part 2, I wrote an I2C MIDI “driver” … Continue reading Raspberry Pi Pico I2C MIDI Interface →

Raspberry Pi Pico MIDI Twitter Followers

After having proved the idea of "music" from Twitter data, I wanted a system that didn't rely on a PC to download the Twitter data, but that could get it "live", so I thought this would be something that I could do with my Raspberry Pi Pico and my Pico Wireless pack. I know there … Continue reading Raspberry Pi Pico MIDI Twitter Followers →

Toy Keyboard USB Matrix Decode with the Pi Pico – Part 2

Having added USB MIDI to my "Toy Keyboard" - I wanted the option to choose either USB or serial MIDI as the output. This returns to the Toy Keyboard USB Matrix Decode with the Pi Pico project to add a serial port option. Warning! I strongly recommend using old or second hand equipment for your experiments. … Continue reading Toy Keyboard USB Matrix Decode with the Pi Pico – Part 2 →

Toy Keyboard USB Matrix Decode with the Pi Pico

I never really got back to looking at my "Toy Keyboard" - I wanted to do the same as the Vintage Phone - create a USB MIDI version with Circuitpython. Well now I have. Here is the result. https://youtu.be/VNmp3-mwysI Warning! I strongly recommend using old or second hand equipment for your experiments. I am not … Continue reading Toy Keyboard USB Matrix Decode with the Pi Pico →
