Arduino RF24 MIDI Interface – Part 2

Having got the basics of "wireless MIDI" working with my nRF24L01 radios, I wanted to take advantage of the inherent "broadcast" nature of radio and see if I could transmit to a number of receivers at the same time. It turned out to be quite a bit more involved than I was expecting! But I … Continue reading Arduino RF24 MIDI Interface – Part 2 →

Raspberry Pi Pico Multi MIDI Router – Part 2

One thing I've wanted to do since building my Raspberry Pi Pico Multi MIDI Router is build a board a bit like ones DeftAudio produces for the Teensy. This posts describes a DIY version of a 4+2 IN, 4+2 OUT MIDI board for the Raspberry Pi Pico. Warning! I strongly recommend using old or second hand … Continue reading Raspberry Pi Pico Multi MIDI Router – Part 2 →

Arduino RF24 MIDI Interface

One thing I've wanted to try is wireless MIDI. I know you can get MIDI over Bluetooth (there are some rather neat commercial "wireless 5-pin MIDI" adaptors you can buy) and I believe people have used MIDI over Wi-Fi by using ipMIDI ("MIDI over Internet Protocol"). But I've had some cheap nrf24L01 radios for a … Continue reading Arduino RF24 MIDI Interface →

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 →

Arduino MIDI Channelizer

This project kicked off from a comment in the "Audio/Midi/DMX using Arduino" Facebook group, where someone wanted to know if an Arduino could receive messages on one channel and change the channel number and send them back out. The answer is yes and this is how it could be done. I've based it on my Arduino … Continue reading Arduino MIDI Channelizer →

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 →

Arduino I2C MIDI Interface – Part 4

This project takes the I2C MIDI relay from part 3 a little further and uses a serial to I2C MIDI relay to drive two different I2C MIDI peripherals. https://youtu.be/7rtbMMmw1Tk 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 … Continue reading Arduino I2C MIDI Interface – Part 4 →
