Arduino Multi MIDI Merge – Part 2

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 MIDI Button Voice Select

Having got as far as an Arduino MIDI Button Bank Selector I went off an ordered some cheap 8-way button pcbs so I can start to experiment with a voice selector too. As I think I mentioned before, I'd really like a set of buttons like you'd find on a real synth 🙂 This is the … Continue reading Arduino MIDI Button Voice Select →

Arduino MIDI Button Bank Select

Having tried this with a Raspberry Pi Pico (and had some odd issues with a RPi V4) I wanted to give it a go with an Arduino too. The basics have already been covered before, so this is relatively quick to set up. Warning! I strongly recommend using old or second hand equipment for your … Continue reading Arduino MIDI Button Bank Select →

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 →
