I've built a number of MIDI merge projects so far (for Arduino and Pico), but they've always taken a relatively simple approach to the merge. They had all ensured that MIDI messages won't be corrupted as they are merged - i.e. only complete messages will be passed on - but they've done nothing to interpret the … Continue reading Arduino Multi MIDI Merge – Part 2

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
Arduino Four-tone Multi-tones
I had reason recently to take a look at the ATmega32U4 microcontroller again. This is used on the Arduino Leonardo and the Sparkfun Pro Micro and includes built-in USB functionality. But it also has four hardware timers, so I thought I'd try to get them working with the three-timer Tone library. https://youtu.be/N0GdLr4a9hM Warning! I strongly … Continue reading Arduino Four-tone Multi-tones
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
PC USB to Arduino Serial MIDI – Part 2
Having built a stand-alone PC USB to Arduino Serial MIDI link, I thought it might also be useful to have a shield that allows a direct PC USB link to the Arduino too. Warning! I strongly recommend using an old or second hand keyboard for your MIDI experiments. I am not responsible for any damage to … Continue reading PC USB to Arduino Serial MIDI – Part 2
PC USB to Arduino Serial MIDI
Whenever I've needed to get a computer to drive my MIDI setup I've wheeled out my Roland UM-ONE PC USB MIDI interface which gives my laptop a MIDI IN and OUT DIN plug. But if I want to get my PC to drive the Arduinos I need to then plug the UM-ONE into one of … Continue reading PC USB to Arduino Serial MIDI
