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 →

MIDI IN for the Raspberry Pi Pico

I was in need of another MIDI IN device, so I thought it would be useful to have another "pack" style interface that supported MIDI IN for new MIDI monitoring type projects. You can see all the other DIY options for Pico MIDI interfaces here: DIY MIDI Interfaces. Warning! I strongly recommend using old or second … Continue reading MIDI IN for the Raspberry Pi Pico →

Arduino Multi MIDI Merge

I've already had a basic MIDI merge project, combining USB MIDI and serial MIDI into a single serial MIDI out (see Arduino USB MIDI Merge). This project takes that forward to provide the options for a whole range of MIDI IN interfaces merging to a single MIDI OUT. In Part 2 I develop the code … Continue reading Arduino Multi MIDI Merge →

Raspberry Pi v1 Model B Synth Board

If you've been following along, you'll know I've been playing around with an original Raspberry Pi v1 model B as the engine for some digital sound synthesis. This is a slight project tangent to build an analog IO and MIDI add-on board. Note that this does not conform to any standard for Raspberry Pi add-ons … Continue reading Raspberry Pi v1 Model B Synth Board →

PC USB-MIDI to MIDI Revisited

This is another take on the PC USB to Arduino Serial MIDI once again taking the Pro Micro I used in part 2. Recall that the Pro Micro board (not to be confused with the Arduino Micro or the Pro Mini) is an Arduino Leonardo compatible smaller board, using the ATmega32U4, which means it has a … Continue reading PC USB-MIDI to MIDI Revisited →

Arduino USB MIDI Merge

This project uses two off-the-shelf Arduino shields to provide a USB and Serial MIDI merge to a single Serial MIDI OUT. https://youtu.be/AB49UNDIrcM 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 … Continue reading Arduino USB MIDI Merge →

MIDI Connections Cheat Sheet

It seems that every time I start to wire-up a MIDI socket or plug I'm looking up, yet again, both what goes to pin 4 and pin 5, and also which pins on a MIDI socket are pins 4 and 5! So I thought I'd hunt around once and for all for everything I can … Continue reading MIDI Connections Cheat Sheet →

Universal Microcontroller MIDI Module

It's been a while since I built a MIDI module... actually, I need the "raw electronics" from a MIDI In/Out interface for a project I'm planning, and wanted it to support either 3.3V or 5V microcontrollers, so this little project was the result. While I was at it, I thought I'd add in a low-pass … Continue reading Universal Microcontroller MIDI Module →
