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 →

Arduino I2C MIDI Interface – Part 3

This project builds on part 2 and takes the generic I2C MIDI interface and turns an Arduino into an I2C MIDI to serial MIDI relay. Note, in part 4, I show how one I2C MIDI controller can send to two I2C MIDI peripherals. https://youtu.be/ppDWNh1-FkY Warning! I strongly recommend using old or second hand equipment for … Continue reading Arduino I2C MIDI Interface – Part 3 →

Arduino I2C MIDI Interface – Part 2

Following on from my Arduino I2C MIDI Interface, this project looks at what is required to get "raw I2C MIDI" working between two Arduinos. In part 1, I used a I2C/IIC to serial module to develop an I2C MIDI interface. In this part, I've developed a "raw" I2C to MIDI transport layer. In part 3, I … Continue reading Arduino I2C MIDI Interface – Part 2 →

Arduino I2C MIDI Interface

This is one of those "I wonder if..." projects. There is little reason for anyone to really do this, but I have a board that only has I2C for IO and naturally I got wondering if it was possible to do MIDI over the I2C interface. This is starting simply, trying it with a standard … Continue reading Arduino I2C MIDI Interface →

Arduino MIDI Slider OLED R2R Waveform Generator

This project moves on a step from my Arduino MIDI Slider R2R Waveform Generator and adds a small 0.96" OLED I2C display. https://youtu.be/MGwdu017e00 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 projects for the main concepts used … Continue reading Arduino MIDI Slider OLED R2R Waveform Generator →

Arduino MPR121 MIDI Touch Piano

A comment on the Arduino MPR121 Touch Piano pointed out that I never went as far as building a 48-note MIDI touch piano. In principle all the bits are there between that post and the Arduino MIDI Touch Piano so this post brings the two together to do just that. https://youtu.be/fdxiHUlXFbY These are the key Arduino … Continue reading Arduino MPR121 MIDI Touch Piano →

MCP4725 and Mozzi – Part 2

So, ignoring the delirium that turned out to be MCP4725 and Mozzi this is using the built-in I2C "TwoWire" support in the Mozzi library to talk to the MCP4725 and generate audio. https://youtu.be/xtVi1blvt1c Warning! I strongly recommend using an old or second hand keyboard for your MIDI experiments. I am not responsible for any damage to expensive … Continue reading MCP4725 and Mozzi – Part 2 →

MCP4725 and Mozzi

I'm going to start this project with at disclaimer - don't bother doing it this way! It was really more of a learning exercise for me - the result of a bit of a "I'm going to push it about as far as I can" obsession this past weekend just to see how far it … Continue reading MCP4725 and Mozzi →

Arduino MPR121 Touch Piano

This project uses on off-the-shelf capacitive touch shield or module to provide touch-sensitive pads for a 12 (recommended for beginners) to 48 (advanced) note "piano". https://youtu.be/rq7UWVNde8M These are the key Arduino tutorials for the main concepts used in this project: Adafruit MPR121 12-Key Capacitive Touch Sensor Breakout Tutorial Sparkfun MPR121 Hookup Guide Arduino Tone … Continue reading Arduino MPR121 Touch Piano →
